用C语言的for循环,打印九九乘法表

用C语言的for循环,打印九九乘法表

C语言:

#include <stdio.h>

 

int main(void)

{

    int row, col;

    for (row = 1; row <= 9; row++)

    {

         for (col = 1; col <= row; col++)

         {

             printf("%d * %d = %-2d ", col, row, row * col);         

         }

         putchar(' ');

        

    }

    return 0;

}

 

运行结果:

1 * 1 = 1

1 * 2 = 2       2 * 2 = 4

1 * 3 = 3       2 * 3 = 6       3 * 3 = 9

1 * 4 = 4       2 * 4 = 8       3 * 4 = 12      4 * 4 = 16

1 * 5 = 5       2 * 5 = 10      3 * 5 = 15      4 * 5 = 20      5 * 5 = 25

1 * 6 = 6       2 * 6 = 12      3 * 6 = 18      4 * 6 = 24      5 * 6 = 30      6 * 6 = 36

1 * 7 = 7       2 * 7 = 14      3 * 7 = 21      4 * 7 = 28      5 * 7 = 35      6 * 7 = 42      7 * 7 = 49

1 * 8 = 8       2 * 8 = 16      3 * 8 = 24      4 * 8 = 32      5 * 8 = 40      6 * 8 = 48      7 * 8 = 56      8 * 8 = 64

1 * 9 = 9       2 * 9 = 18      3 * 9 = 27      4 * 9 = 36      5 * 9 = 45      6 * 9 = 54      7 * 9 = 63      8 * 9 = 72      9 * 9 = 81
