以下是 C 语言代码,可实现打印倒三角九九乘法表:
```
#include <stdio.h>
int main() {
int i, j;
for (i = 9; i >= 1; i--) {
for (j = i; j >= 1; j--) {
printf("%d*%d=%2d ", i, j, i*j);
}
printf("\n");
}
return 0;
}
```
输出结果为:
```
9*9=81 9*8=72 9*7=63 9*6=54 9*5=45 9*4=36 9*3=27 9*2=18 9*1= 9
8*8=64 8*7=56 8*6=48 8*5=40 8*4=32 8*3=24 8*2=16 8*1= 8
7*7=49 7*6=42 7*5=35 7*4=28 7*3=21 7*2=14 7*1= 7
6*6=36 6*5=30 6*4=24 6*3=18 6*2=12 6*1= 6
5*5=25 5*4=20 5*3=15 5*2=10 5*1= 5
4*4=16 4*3=12 4*2= 8 4*1= 4
3*3= 9 3*2= 6 3*1= 3
2*2= 4 2*1= 2
1*1= 1
```
