C++ function arguments doubt?

[rajeshs]

I have one doubt with C++ function arguments declaration;

Normally if want to declare more than one variables with same type,C++ have option to declare with in same declaration ; ( int a,b ; this will declare a and b same int type);

Why this option is disabled when come to function arguments ? (We can't specify function arguments as void display(int a,b) ; we should specify type for both argumrnts seperatly)

Is there any reason to do this?
Why language designers disabled this option in function argunments?

Hi,

Maybe then the compiler needs to know if "b" is a defined type.

When defining variables the compiler reads the first word and know wich type are the varaibles that will follow separated by ",".

Then, in a function you can do this: "foo(int a,b,double c)", and then the compiler will search for type "b" that don't exists.

A coder writes a lot of code lines, so, are you complaining to write some words?

In regular code semicolon is used as statement separator. Inside function declaration the comma character is used as a separator. Thus you can associate variable names with the type in regular code but not in function arguments. Consider this example:


void function(int, int);
The above statement is valid (you can skip variable names in function prototypes). Now what about this:

void function(int a, b);
is "b" a variable name or a data type?
