Arrow operator (->) usage in C and C++ howto
//Arrow operator in unions:
// C program to show Arrow operator
// used in structure
#include <stdio.h>
#include <stdlib.h>
// Creating the union
union student {
char name[80];
int age;
float percentage;
};
// Creating the union object
union student* emp = NULL;
// Driver code
int main()
{
// Assigning memory to struct variable emp
emp = (union student*)
malloc(sizeof(union student));
// Assigning value to age variable
// of emp using arrow operator
emp->age = 18;
// DIsplaying the assigned value to the variable
printf("%d", emp->age);
}
