用C语言的while循环，打印九九乘法表

用C语言的while循环：

#include

int main(void)

{

int row = 1;

while (row <= 9)

{

int col = 1;

while (col <= row)

{

printf("%d * %d = %d\t", col, row, col * row);

col += 1;

}

printf("\n");

row += 1;

}

printf("\n");

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
