c++输出九九乘法表

Sure! Here is the code to generate the multiplication table:

#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 code uses nested loops to iterate through the numbers from 1 to 9 and prints out the multiplication table. Each line represents a row, and each entry within a row represents the multiplication of the corresponding row and column numbers.
