C Programming - Variable Number of Arguments - Discussion

Argument: An argument represents the value that you pass to a procedure parameter when you call the procedure. The calling code supplies the arguments when it calls the procedure.

Parameter: A parameter represents a value that the procedure expects you to pass when you call it. The procedure's declaration defines its parameters.

What is the difference between fixed arguments and variable arguments?

I agree with you. Vasu. But it necessary to know about some possibilities and Good programmer characteristics are to KISS (Keep In Source Simple) that's creativity generate if we know some possibilities so learn more and be effective, simple, give user friendly output that's learn from here.

Bye the way I thankful of indiabix to give me many cases to learn and grow of my skills.

Why is software questions so complicated when in real world programming even person with basic or sufficient knowledge can become a very efficient programmer with minimal program concepts.

//eg...
void fun(char *msg, ...);

int main()
{
fun("IndiaBIX", 1, 4, 7, 11, 0);
return 0;
}
void fun(char *msg, ...)
{
va_list ptr;
int num;
va_start(ptr, msg);
num = va_arg(ptr, int);
num = va_arg(ptr, int);
printf("%d", num);
}

One example please.

Default arg are passed from right to left or from end of argument list while fixed arguments passed to the function from beginning of argument list.
