Parameter vs argument vs attribute

Lionel Badiou CodeFutures Software. Originally posted by Roger Chung-Wee: I think of a parameter as being part of a method's API, it's what you declare in the parameter list of the method signature. To me, the argument is the value passed into the method at runtime, so the arg has to comply with the type of parameter.

parameter vs argument vs attribute

Difference between attribute and parameter. Optional 'thank-you' note:. HiI want to the difference between attribut and parameter and difference between argument and parameter regards Jayant. Henrik Engert. It is just a definition for what the method takes. You can call them whatever you like. You can say for example a method uses arguments and a user passes parameters. Lionel Badiou. Hope that helps.

David Harkness. To me, attribute is more akin to a field, though mostly when talking about JavaBeans. My view comes from the dictionary definition of attribute: "A quality or characteristic inherent in or ascribed to someone or something. In that sense, I view the complete list of parameter types as a single attribute of a method. That list combined with the name and return type make up a method's signature, which really could also be viewed as an attribute itself.

Roger Chung-Wee. I think of a parameter as being part of a method's API, it's what you declare in the parameter list of the method signature. Layne Lund. I think Roger has given what is typically accepted as the formal definitions of argument and parameter. As other's have posted, the two terms are often used interchangeably, too, unfortunately. I'm not sure what the word "attribute" has to do with this discussion.

As far as I know, this is not a commonly used term in the Java programming language. Junilu Lacar. I like As for "parameter" vs. An "argument" would probably be an actual parameter in most cases that they are referred to as such. At the same time, s becomes the actual parameter argument in the call to setProp.

I got parameter and argument kind of mixed up and did not really pay attention to when to use one and when to use the other.

An argument is an expression used when calling the method. Here i and f are the parameters, and anInt and 2. Learn more.

We use this convention italian as well. I like this quote from MSDN : " You can think of the p arameter as a p arking space and the a rgument as an a utomobile.

You get access to the list of argument values passed to the function. Consequently you don't get a list of the parameter names of the function, javascript doesn't give you a way to get that info.

Drop me a light on it. Thank you in advance. Seema Ahuja. This atrribut can be an onject and that object has properties. Hope that explains.

Thank you, Seema, But I don't think i really catch the difference between argument and parameter. What if the term 'argument' or 'parameter' is used both by the method or by someone that invokes the method?

Everything is OK. Isn't it?

Bachi Taurean. Hi william, Arguments tell us what is the value that you are giving. Parameters tell us which type data type of value is expected from the caller. Seema am i right? Hi Bachi, I get something, but i'm not sure. The difference is subtle, I think. Argument is a variable that you pass to the method, it should be decided by compile time, though it may have different values in runtime.

Parameter is just used as a local variable in a method.

Celinio Fernandes. I like Siddharth Purandare. Hey William, Let me know if this helps!!! Hi Siddharth, I agree with you, but i really want to know the difference between argument and parameter.While I was playing with the functions, I was wondering what is the difference between arguments and parameters. You might also have the same doubt, right?

I thought both are the same. But they are not. Sometimes you will hear the two terms used interchangeably and most people will know what you mean, but there are some actual differences. So, I have done some research and I thought I should share this with you. By the end of this article, you will have a clear idea about both of these programming terms. If you have come for the quick answer, here is the main difference between arguments and parameters. A parameter is a variable in a method definition or function definition.

They are also called formal parameters. When we call a method, arguments are the real data that we pass into the parameters of the method.

At the end of this article, I will tell you one cool trick to help you distinguish easily between arguments and parameters. Here is a simple Python program to show you the differences between arguments and parameters.

This program has a method or function that takes two numbers as input and outputs the sum of those numbers. Take a look at this simple Python program to add two numbers. We have a function called addNumbers which contains two values inside the parenthesis, para1and para2. These two values are called parameters. I named it para1 and para2 so that you can understand quickly. These are two local variables, having a lifetime only inside the function. They can take any values that are passed when we call the method.

So, these are the parameters.Join Stack Overflow to learn, share knowledge, and build your career. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. What is the difference between attribute and parameter and argument? And how does this works? And if i pass a argument dynamically then whether it will be called parameter or argument.

A Parameter is what appears in the definition of the method. An Argument is the instance or primitives passed to the method during runtime.

The second line of your code wouldn't even compile. The first line is unclear in terms of whether you're declaring an instance field or a local variable - both of which are more standard Java terminology than "attribute".

Attribute is what you put on top, argument is what you pass from a caller viewpoint, parameter is what's passed from a callee viewpoint. That, and java calls it annotations rather than attributes. And attributeyou can call, a piece of information about containing entity. AlokMishra: You may use parameter and argument interchangably, but they're quite distinct terms, and I think it's worth trying to use them properly.

Active Oldest Votes. JimmyB JimmyB I believe this is also how it's used in the JLS and other reliable documents. Do you have any source that calls them "attributes" in widespread usage? You can't assume specific terminology from such a general document. It specifies "Properties" and "Attributes" as synonyms of fields. In Cfor example, these are 3 very distinct class members.

Stack Overflow works best with JavaScript enabled.A function is an organized set of statements to perform a specific task. Functions are useful in repeating a piece of code, so they provide code reusability.

Programming languages such as C language consist of built-in functions like printf. It is also possible to write functions by the programmer.

Those are called user-defined functions. Argument and Parameter are terms associated with functions. The key difference between argument and parameter is that an argument is the data passed at the time of calling a function while a parameter is a variable defined by a function that receives a value when the function is called. An argument is an actual value while a parameter is a placeholder.

Overview and Key Difference 2. What is an Argument 3. What is a Parameter 4. Similarities Between Argument and Parameter 5. In C programming language, the main is a function. It indicates the starting point of the execution. Writing every statement in the main function can make the program very complex.

It can be hard to test and debug. To overcome this problem, the main program can be divided into several functions or methods.

Those functions can be called by the main program. The return type is the data type returned by the function. The function name can be named to identify what the function is about. It is the actual name of the function. Content to execute is inside a pair of curly braces. A simple example of a function is as follows. To call this method, there should be a statement as add ; in the main program. That will invoke the function.

Functions can be made more adaptable using arguments and parameters. Refer bellow piece of code. In main, there is a statement add 4,6. They are values that are passed to a function when it is invoked. In the main program, again there can be a statement as add 5,2. Now the arguments passed to the add function are 5 and 2.

An argument is also called as an actual argument or actual parameter. A parameter is a variable defined by a function, that receives a value when a function is called.

The parameter can also be known as a Formal parameter or formal argument. This concept can be easily understood by an example.

Refer the bellow piece of code. According to the above code, no1 and no2 in void multiply int no1,int no2 are the parameters.The key difference between attribute and parameter is that an attribute is a variable of any type that is declared directly in a class while a parameter is a variable defined by the function that receives a value when it is called.

In programming languages such as Java, there are concepts like objects, classes and functions. When coding, the programmer should follow the specific syntax related to the programming language. An attribute is used with classes and objects while a parameter is used with functions or methods.

This article discusses the difference between attribute and parameter. Overview and Key Difference 2. What is Attribute 3. What is Parameter 4. Programming languages such as Java supports Object Oriented programming. This programming paradigm is based on objects. An object has a state and behaviour. The state is represented by the data values.

They are also called as fields or attributes. The behaviour or the functionality is represented by methods. A class is a blueprint to create an object. Therefore, an object is an instance of a class. A student object can hav e attributes such as student id and name. An Employee can have attributes such as employee ID, name, salary and department. An Animal object can have attributes such as name, favourite food etc. According to the above program, the Rhombus class has two attributes that are diagonal1 and diagonal2.

It also has the constructor and a method to calculate the area. In the main program, an object of Rhombus is created. Two values are passed to the constructor, and those will assign to the diagonal1 and diagonal2 attributes. When calling the calArea method, the area of the Rhombus is calculated, and it will return the answer, which is a double value. Finally, the calculated area will print on the screen. The two diagonal values are the attributes of the class and of the object r1.

A Function is a major concept in programming. It is a set of statements to perform a specific task. Functions increase code reusability. There can be predefined functions provided by the programming language. The programmer can also write his own functions. They are called as user-defined functions. The term parameter is associated with the function.
