    1计算零件数

    #include<stdio.h>
     
    int main()
    {
        int total;
        for (int i = 11; i < 23; i++)
        {
            total = i * 9 + 5;
            if (total % 4 == 2 && total % 7 == 3)
            {
                printf("%d\n", total);
                return 0;
            }
        }
        return 0;
    }
    

    2走台阶

    #include<stdio.h>
     
    int step(int n);
    
    int main()
    {
        int a;
        a = step(10);
        printf("Result=%d", a);
        return 0;
    }
    
    int step(int n)
    {
        if (n == 1)
            return 1;
        if (n == 2)
            return 2;
        else
            return step(n - 1) + step(n - 2);
    }
    

    3将数据按照奇偶排序

    #include<stdio.h>
     
    
    int main()
    {
        int old[10];
        int new[10];
        int temp;
        int count = 0;
        printf("Input 10 numbers:\n");
        for (int i = 0; i < 10; i++)
        {
            scanf("%d", &old[i]);
        }
        for (int i = 0; i < 9; i++)
        {
            for (int j = 0; j < 10-i-1; j++)
            {
                if (old[j] > old[j + 1])
                {
                    temp = old[j]; old[j] = old[j + 1]; old[j + 1] = temp;
                }
            }
        }
        for (int i = 0; i < 10; i++)
        {
            if (old[i] % 2 != 0)
            {
                new[count] = old[i];
                count++;
            }
        }
        for (int i = 0; i < 10; i++)
        {
            if (old[i] % 2 == 0)
            {
                new[count] = old[i];
                count++;
            }
        }
        printf("Output: ");
        for (int i = 0; i < 9; i++)
            printf("%d,", new[i]);
        printf("%d\n", new[9]);
        return 0;
    }
    

    4三色球分组

    #include<stdio.h>
     
    
    int main()
    {
        int red = 0;
        int white = 0;
        int black = 0;
        int count = 0;
        printf("The result:\n");
        for (red = 1; red < 4; red++)
            for (white = 1; white < 6; white++)
                for (black = 0; black < 7; black++)
                    if (red + white + black == 8)
                    {
                        printf("red:%4d white:%4d black:%4d\n", red, white, black);
                        count++;
                    }
        printf("sum=%4d\n", count);
                        
        return 0;
    }
    

    5同构数

    #include<stdio.h>
     
    
    int main()
    {
        int i;
        for (i = 1; i < 100; i++)
        {
            if (i < 10)
            {
                if (i == (i * i) % 10)
                    printf("m=%3d\t\tm*m=%6d\n", i, i * i);
            }
            else
            {
                if (i == (i*i)%100)
                    printf("m=%3d\t\tm*m=%6d\n", i, i * i);
            }
        }
        return 0;
    }
