### 回答1:
Sure, here is the code for printing the multiplication table in C language:
```c
#include <stdio.h>
int main() {
int i, j;
for (i = 1; i <= 9; i++) {
for (j = 1; j <= i; j++) {
printf("%d*%d=%d\t", j, i, i*j);
}
printf("\n");
}
return 0;
}
```
This will print the multiplication table from 1 to 9.
### 回答2:
#include <stdio.h>
int main() {
int i, j;
for(i = 1; i <= 9; i++) {
for(j = 1; j <= i; j++) {
printf("%d * %d = %d ", j, i, j * i);
}
printf("\n");
}
return 0;
}
运行程序后,屏幕上会输出如下所示的九九乘法表:
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

九九乘法表是一个经典的程序练习题,可以通过使用循环结构和格式化输出语句来实现。下面是一个使用C语言编写的九九乘法表的示例程序:
```c
#include <stdio.h>
int main() {
int i, j;
// 外层循环控制打印的行数
for (i = 1; i <= 9; i++) {
// 内层循环控制打印的列数
for (j = 1; j <= i; j++) {
printf("%d * %d = %d\t", j, i, i * j);
}
printf("\n"); // 换行
}
return 0;
}
```
程序中使用了两个嵌套的循环,外层循环控制打印的行数,内层循环控制打印的列数。在内层循环中,使用`printf`函数以格式化的方式输出乘法表的每一项。其中,`%d`用于输出整数,`\t`表示输出一个制表符,`\n`表示输出一个换行符。
运行程序后,屏幕上会输出如下所示的九九乘法表:
```
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
```
