C++输出一个九九乘法表

Sure, here's the code for printing a 9x9 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 output the multiplication table in the console.
