Question

一道很简单的C语言练习题 我想看看是不是我理解错题目了

Problem Description

Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You
must have found that some problems have the same titles with this one,
yes, all these problems were designed for the same aim.

Input

The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.

Output

For
each pair of input integers a and b you should output the sum of a and b
in one line, and with one line of output for each line in input.

Sample Input
1 5
10 20

Sample Output
6
30

谁帮我写出这个题目的代码 我比较自己的看一下 谢谢 求不鄙视
请问这里的Sample Input 和 Ooutput意思是不是一次性输入四个数 然后一次性输出两个结果？

Answer 1

#include<iostream>
using namespace std;
int main(){
    int a,b;

while(cin>>a>>b)cout<<a+b<<endl;
    return 0;

}

请问这里的Sample Input 和 Ooutput意思是不是一次性输入四个数 然后一次性输出两个结果？

——是样例输入输出，用来告诉你输入和输出的格式，实际的用于测试你程序是否正确的数据可能远比这个要多

Answer 2

是一次性输入，也是一次性输出的。
#include <stdio.h>
int main()
{
int a,b,c,d,sum1,sum2;

scanf("%d %d %d %d",&a,&b,&c,&d);
sum1=a+b;
sum2=c+d;
printf("%d\n%d",sum1,sum2);

return 0;
}

Answer 3

#include<stdio.h>
int main()
{
int a,b,sum;
while(scanf("%d %d",&a,&b))
{
sum=a+b;
printf("%d\n",sum);
}
return 0;
}

Answer 4

#include <stdio.h>

int main()
{
int a,b;

while(scanf("%d%d",&a,&b)!=EOF)
{
printf("%d\n",a+b);
}

return 0;
}
