题目：
Given three integers A, B and C in [?2?63?? ,2?63?? ], you are supposed to tell whether A+B>C.
Input Specification:
The first line of the input gives the positive number of test cases, T (≤10). Then T test cases follow, each consists of a single line containing three integers A, B and C, separated by single spaces.
Output Specification:
For each test case, output in one line Case #X: true if A+B>C, or Case #X: false otherwise, where X is the case number (starting from 1).
Sample Input:
3
1 2 3
2 3 4
9223372036854775807 -9223372036854775808 0
Sample Output:
Case #1: false
Case #2: true
Case #3: false
题意：
判断a+b>c成立不成立。
64位的long long 不行
128位的long double还不行吗？
我的代码：
#include<bits/stdc++.h>
using namespace std;int main()
{
int N;cin>>N;for(int i=1;i<=N;i++){
long double a,b,c;cin>>a>>b>>c;string flag=a-c+b>0?"true":"false";cout<<"Case #"<<i<<": "<<flag<<endl;}return 0;
}
