九九乘法表程序设计
C
----------------------------------------------------
//九九乘法表
#include <stdio.h>
main(){
int i,j;
for(i=1;i<=9;i++){
for(j=1;j<=9;j++){
if(i>=j)
printf("%d*%d=%d",j,i,j*i);
if(j*i<10)
printf(" ");
else
printf(" ");
}
printf("\n");
}
}

Java

//九九乘法表
public class chengfa {
public static void main(String[] args) {
for(int i=1;i<=9;i++){
for(int j=1;j<=i;j++){
System.out.print(j+"*"+i+"="+j*i);
if(i*j<10){ //处理乘机超过个位时不对齐的问题
System.out.print(" ");
}else{
System.out.print(" ");
}
}
System.out.println(" ");

}

C++
---------------------------------------------------------------------
#include <iostream>

C#
---------------------------------------------------------------------
