Function in C

Functions allow the programmer to modularize a program. The format of function definition is :

Return-value-type function-name (parameter-list)
{
declarations…..

statements…..
}

/*Function*/
/*Example -- A programmer-defined square function*/
/*Fig 5.13 -- page 147*/

#include stdio.h /* I’m not typing <> symbol cause its illegal in this blog*/

int square (int); /*Funtion prototype*/

int main ()
{
int x;

for ( x = 1; x <= 10; x++)
printf ("%d ", square (x)); /*calling a function*/
printf ("\n");
return 0;
}

int square (int y) /*Function*/
{
return y*y;
}
