▲C語言實現乘法口訣表的輸出
①正三角輸出
#include<stdio.h>int main(){int i, j = 0;for (i = 1; i <= 9; i++){for (j = 1; j <=i; j++){printf("%d*%d=%2d\t", i, j, i*j);}printf("\n");}return 0;②倒三角輸出乘法口訣表
#include<stdio.h>int main(){int i, j = 0;for (i = 1; i <= 9; i++){for (j = i; j <=9; j++){printf("%d*%d=%2d\t", i, j, i*j);}printf("\n");}return 0;③矩陣形式輸出
#include<stdio.h>int main(){int i, j = 0;for (i = 1; i <= 9; i++){for (j = 1; j <=9; j++){printf("%d*%d=%2d\t", i, j, i*j);}printf("\n");}return 0;
