    printf("Enter three sides of triangle: \n");
    scanf("%d%d%d", &side1, &side2, &side3);
  
    if((side1 + side2) > side3)
    {
        if((side2 + side3) > side1)
        {
            if((side1 + side3) > side2)
            {
                printf("Triangle is valid.");
            }
            else
            {
                printf("Triangle is not valid.");
            }
