C语言实现输出九九乘法表

include<stdio.h>
int main()
{
    int i, j, result;
    printf("\n");
    for (i = 1; i < 10; i++)
    {
        for (j = 1; j <= i; j++)
        {
            result = i * j;
            printf("%d*%d=%-3d", i, j, result); /*-3d表示左对齐，占3位*/
        }
        printf("\n"); /*每一行后换行*/
    }
}
