C语言输出打印乘法口诀表

#include<stdio.h>int main(){int i, j, result = 0;for (i = 1; i <= 9; i++){for (j = 1; j <= i; j++){result = i*j;printf("%d*%d=%-3d", i, j, result);printf(" ");}printf("\n");}system("pause");return 0;}

  要想输出灵活一点，可以将其写成函数的形式，输出指定大小的乘法口诀表。

#include<stdio.h>void fun(int n);int main(){int n;printf("输入需要口诀表的大小\n");scanf("%d", &n);fun(n);system("pause");return 0;}void fun(int n){int i, j, result = 0;for (i = 1; i <= n; i++){for (j = 1; j <= i; j++){result = i*j;printf("%d*%d=%-3d", i, j, result);printf(" ");}printf("\n");}}
