c语言把1～100之间能被7整除的数，以每行5个的形式在屏幕上输出

Sure, here's the C code to output all numbers between 1 and 100 that are divisible by 7, in rows of 5:

#include <stdio.h>

int main()
{
    int i;

    for (i = 1; i <= 100; i++)
    {
        if (i % 7 == 0)
        {
            printf("%d ", i);
            if (i % 35 == 0)
                printf("\n");
        }
    }

    return 0;
}

I hope that helps!
