    int size = 2;
    int level = 3;
    for (int i = 0; i < level; i++)
    {

        {
            for (int j = 0; j < (level - i) * size - k - 1; j++)
                printf(" ");
            if (k != size - 1)
            {
                for (int j = 0; j <= i; j++)
                {
                    printf("/");
                    for (int l = 0; l < k * 2; l++)
                        printf(" ");
                    printf("\\");
                    for (int l = 0; l < (size - k - 1) * 2; l++)
                        printf(" ");
                }
            }
            else
            {
                for (int j = 0; j <= i; j++)
                {
                    printf("/");
                    for (int l = 0; l < (size - 1) * 2; l++)
                        printf("_");
                    printf("\\");
                }
            }
