那些程式語言們共通的三個基本結構

選擇（selection）結構：平均戰鬥力

• Scratch

• Python

liubei=input("刘備的战鬥力=")

guanyu=input("関羽的战鬥力=")

zhangfei=input("張飛的战鬥力=")

average=(int(liubei)+int(guanyu)+int(zhangfei))/3

print("三人平均战鬥力=", average)

if 0<=average<=5:

print("弱弱的")

if 6<=average<=8:

print("尚可")

if 9<=average<=10:

print("超強")

• C++

#include <iostream>

using namespace std;

int main(void) {

int liubei, guanyu, zhangfei, average;

cout<<"劉備的戰鬥力=";

cin>>liubei;

cout<<"關羽的戰鬥力=";

cin>>guanyu;

cout<<"張飛的戰鬥力=";

cin>>zhangfei;

average=(liubei+guanyu+zhangfei)/3;

cout<<"三人平均戰鬥力=";

cout<<average;

cout<<"\n";

if ((0<=average)&&(average<=5))

cout<<"弱弱的";

if ((6<=average)&&(average<=8))

cout<<"尚可";

if ((9<=average)&&(average<=10))

cout<<"超強";

return 0;

}

• Java

import java.util.Scanner;

public class Power {

public static void main(String[] args) {

int liubei, guanyu, zhangfei, average;

Scanner s=new Scanner(System.in);

System.out.print("劉備的戰鬥力=");

liubei=s.nextInt();;

System.out.print("關羽的戰鬥力=");

guanyu=s.nextInt();;

System.out.print("張飛的戰鬥力=");

zhangfei=s.nextInt();;

average=(liubei+guanyu+zhangfei)/3;

System.out.print("三人平均戰鬥力=");

System.out.println(average);

if ((0<=average)&&(average<=5))

System.out.print("弱弱的");

if ((6<=average)&&(average<=8))

System.out.print("尚可");

if ((9<=average)&&(average<=10))

System.out.print("超強");

}

}
