用c语言输出九九乘法表要求输出三列，输出格式为輸出格式 : 1X1 = 1 2X1 = 2 3X1 = 3 1X2 = 2 2X2 = 4 3X2 = 6 … … … 1X9 = 9 2X9 = 18 3X9 = 27

好的，下面是C语言代码实现九九乘法表，输出格式为每列三个的形式：

#include <stdio.h>

int main() {
    int i, j;
    for (i = 1; i <= 9; i++) {
        for (j = 1; j <= 3; j++) {
            printf("%dX%d = %-2d  ", j, i, i*j);
        }
        printf("\n");
        if (i % 3 == 0) {
            printf("\n");
        }
    }
    return 0;
}

输出结果为：

1X1 = 1    2X1 = 2    3X1 = 3    
1X2 = 2    2X2 = 4    3X2 = 6    
1X3 = 3    2X3 = 6    3X3 = 9    

1X4 = 4    2X4 = 8    3X4 = 12   
1X5 = 5    2X5 = 10   3X5 = 15   
1X6 = 6    2X6 = 12   3X6 = 18   

1X7 = 7    2X7 = 14   3X7 = 21   
1X8 = 8    2X8 = 16   3X8 = 24   
1X9 = 9    2X9 = 18   3X9 = 27   

希望能帮到你！

用c语言打印九九乘法表

Sure, here's the code to print the multiplication table in 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 out the multiplication table from 1x1 to 9x9.
