好的,以下是用 C 语言输出九九乘法表并且输出三列的代码:
```c
#include <stdio.h>
int main() {
int i, j;
for(i = 1; i <= 9; i++) {
for(j = 1; j <= 9; j++) {
printf("%d * %d = %d\t", i, j, i*j);
if(j % 3 == 0) {
printf("\n");
}
}
if(i % 3 == 0) {
printf("\n");
}
printf("\n");
}
return 0;
}
```
输出结果如下:
```
1 * 1 = 1 1 * 2 = 2 1 * 3 = 3
1 * 4 = 4 1 * 5 = 5 1 * 6 = 6
1 * 7 = 7 1 * 8 = 8 1 * 9 = 9
2 * 1 = 2 2 * 2 = 4 2 * 3 = 6
2 * 4 = 8 2 * 5 = 10 2 * 6 = 12
2 * 7 = 14 2 * 8 = 16 2 * 9 = 18
3 * 1 = 3 3 * 2 = 6 3 * 3 = 9
3 * 4 = 12 3 * 5 = 15 3 * 6 = 18
3 * 7 = 21 3 * 8 = 24 3 * 9 = 27
4 * 1 = 4 4 * 2 = 8 4 * 3 = 12
4 * 4 = 16 4 * 5 = 20 4 * 6 = 24
4 * 7 = 28 4 * 8 = 32 4 * 9 = 36
5 * 1 = 5 5 * 2 = 10 5 * 3 = 15
5 * 4 = 20 5 * 5 = 25 5 * 6 = 30
5 * 7 = 35 5 * 8 = 40 5 * 9 = 45
6 * 1 = 6 6 * 2 = 12 6 * 3 = 18
6 * 4 = 24 6 * 5 = 30 6 * 6 = 36
6 * 7 = 42 6 * 8 = 48 6 * 9 = 54
7 * 1 = 7 7 * 2 = 14 7 * 3 = 21
7 * 4 = 28 7 * 5 = 35 7 * 6 = 42
7 * 7 = 49 7 * 8 = 56 7 * 9 = 63
8 * 1 = 8 8 * 2 = 16 8 * 3 = 24
8 * 4 = 32 8 * 5 = 40 8 * 6 = 48
8 * 7 = 56 8 * 8 = 64 8 * 9 = 72
9 * 1 = 9 9 * 2 = 18 9 * 3 = 27
9 * 4 = 36 9 * 5 = 45 9 * 6 = 54
9 * 7 = 63 9 * 8 = 72 9 * 9 = 81
```
