<u>Example-</u> C Program
#include<stdio.h>

// function declaration
float exitexample ( float x );
// Driver program
int main( )

printf ( "\nEnter some number for finding square \n");
scanf ( "%f", &a ) ;
// function call
b = exitexample ( a ) ;
printf ( "\nSquare of the given number %f is %f",a,b );
/*This will not printed as exit function is in exitexample() function*/
}
float exitexample ( float x ) // function definition
{
exit(0); //exit function
float p ;
p = x * x ;
return ( p ) ;
}
