A + B ||| 问题
题目描述:
Your task is to Calculate a + b.
输入格式:
Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.
输出格式:
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.
老问题求A+B,重点看格式:
输入:
1 5
10 20
0 0
输出:
6
30
再结合题意可以看到题目要求的是,多组输入,每组输入两个数,但以a和b分别为0表示结束输入,这组不作处理,然后再结合样例就明白了。
因此这道题目,我们可以参考前面A+B第一种的格式写法,然后额外加一个a,b都为0时跳出的特殊判断即可
思路有了,C语言代码就来了:
#include<stdio.h>
int main()
{
int a,b;
while(scanf("%d%d",&a,&b)==2)
{
if(a== 0 && b==0)
break;
printf("%d\n",a+b);
}
return 0;
}
参考C++代码:
#include<iostream>
using namespace std;
int main()
{
int a,b;
while(cin>>a>>b)
{
if(a==0&&b==0)
break;
cout<<a+b<<endl;
}
return 0;
}
参考Java代码:
import java.util.Scanner;
public class Main {
public static void main(String[] args){
Scanner scanner = new Scanner(System.in);
while(scanner.hasNext()){
int a = scanner.nextInt();
int b = scanner.nextInt();
if(a==0 && b==0)
break;
int c=a+b;
System.out.println(c);
}
}
}
参考Python代码:
while True:
try:
n=input()
for i in range(int(n)):
a,b= map(int,input().strip().split())
print(a+b)
except EOFError:
break
