Operations on struct variables in C
Last Updated :

In C, the only operation that can be applied to struct variables is assignment. Any other operation (e.g. equality check) is not allowed on struct variables.
For example, program 1 works without any error and program 2 fails in compilation.
Program 1
#include <stdio.h>
struct Point {
int x;
int y;
};
int main()
{
struct Point p1 = {10, 20};
struct Point p2 = p1;
printf ( " p2.x = %d, p2.y = %d" , p2.x, p2.y);
getchar ();
return 0;
}

Program 2
#include <stdio.h>
struct Point {
int x;
int y;
};
int main()
{
struct Point p1 = {10, 20};
struct Point p2 = p1;
if (p1 == p2)
{
printf ( "p1 and p2 are same " );
}
getchar ();
return 0;
}
