    printf("Enter Side of  length-2:");
    scanf("%d",&side2);
    printf("Enter Side of  length-3:");
    scanf("%d",&side3);
    if(side1==side2 && side1==side3|| side2==side3 && side2==side1)
        printf("Equilateral");
    else if(side1==side2 && side1!=side3 || side1==side3 && side1!=side2)
        printf("Isoceles");
    else
