Example:
#include <stdio.h>
int mul(int, int); /* Function prototype */
int main()
{
int a = 0, b = 3, c;
c = mul(a, b);
printf("c = %d\n", c);
return 0;
}
/* Two return statements in the mul() function */
int mul(int a, int b)
{
if(a == 0 || b == 0)
{
return 0;
}
else
{
return (a * b);
}
}
Output:
c = 0
#include<stdio.h> #include<stdlib.h> int main() { union test { int i; float f; char c; }; union test *t; t = (union test *)malloc(sizeof(union test)); t->f = 10.10f; printf("%f", t->f); return 0; }
