Function standards in C programming

There are two types of function parameter standard:

1. ANSI standard

In this standard function definition is written as

int calculate(int a, int b){

    int c;

    c=a+b;

    return c;

}

This standerd is also called as modern style.

2. K and K standard

int calculate(a, b)

int a,b;

{

    int c;

    c=a+b;

    return c;

}

This standard is also called as old style.You should also known this style if you want to read old c code.

Examples:

void main(){

    int i=kkstandard(5,5,5.0f,'5');

    printf("%d",i);

    getch();

}

int kkstandard (a,b,f,c)

int a,b;

char c;

float f;{

    int x=a+b+c+f;

    return x;

}

Output: 68
