Create check triangle is equilateral, isosceles ot scalene

#include <stdio.h>

int main()
{
    int side1,side2,side3;

    printf("Enter value of side 1 = ");
    scanf("%d",&side1);

    printf("Enter value of side 2 = ");
    scanf("%d",&side2);

    printf("Enter value of side 3 = ");
    scanf("%d",&side3);

    if (side1 == side2 && side2 == side3 && side3 == side1) {
        printf("Its a Equilateral Triangle");
    } else if (side1 != side2 && side2 != side3 && side3 != side1) {
        printf("Its a Scalene Triangle");
    } else {
        printf("It's an Isosceles Tirangle");
    }
}
