C语言编程：10以内加减法，根据输入题数出题，判断做题是不是正确，最后计算分数。

Posted 2023-05-11

使用C语言编程。是可供小学数学的运算程序。

参考技术A #include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define SWAP(a,b,c) (c)=(a);(a)=(b);(b)=(c);
void main()

int i,n,fen=0,p;
int a,b,num;
printf("你要几道题?");
scanf("%d",&n);
srand(time(NULL));
for(i=0;i<n;i++)
a=rand()%10+1;
b=rand()%10+1;
if(p)p=0;
printf("%d + %d = ",a,b);
scanf("%d",&num);
if(num==a+b)fen++;

else
p=1;
if(a<b)SWAP(a,b,p);
printf("%d - %d = ",a,b);
scanf("%d",&num);
if(num==a-b)fen++;



printf("总分 %d，得分%d ",n,fen);

Java实现随机出题，10道10以内加减法计算

package com.swift;

import java.awt.Toolkit;
import java.util.Scanner;

public class PlusQuiz {

    public static void main(String[] args) {
        int i=0;
        int number1=0,number2=0;
        for(;;) {
            number1=(int) (Math.random()*10);
            number2=(int) (Math.random()*10);
            //加法部分
            System.out.println("What is "+number1+"+"+number2+"?");
            Scanner scan=new Scanner(System.in);
            int answer=scan.nextInt();
            if(answer==number1+number2) {
                System.out.println("√");
                Toolkit.getDefaultToolkit().beep();
                //System.out.println(‘\007‘);
                
            }else {
                System.out.println("×");
                System.out.println(number1+"+"+number2+" should be "+(number1+number2));
            }
            //减法部分
            if(number1<number2) {
                int temp;
                temp=number1;
                number1=number2;
                number2=temp;
            }
            System.out.println("What is "+number1+"-"+number2+"?");
            int answer2=scan.nextInt();
            if(answer2==number1-number2) {
                System.out.println("√");
                for(int time=0;time<6;time++)
                Toolkit.getDefaultToolkit().beep();
            }else {
                System.out.println("×");
                System.out.println(number1+"-"+number2+" should be "+(number1-number2));
            }
            //判断加减法完成次数
            i++;
            if(i==5) {
                break;
            }
        }
    }
