What is the difference between an argument and a return value?  How many arguments can a function call have?

 

There are 3 main differences:

Arguments:

• Arguments or parameter is what is input to a function.
• There can be many arguments to a function.
• There can be 0 arguments to invoke a function

Return value:

• It is the value which the function returns.
• There is only a single return value.
• All functions have a return type ( even void is a return type)

The maximum number of arguments is 253 for a single function.
