1065. A+B and C (64bit) (20)

判题程序 Standard 作者 HOU, Qiming

Given three integers A, B and C in [-263, 263], 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

#include <iostream>
#include <fstream>
#include <cmath>
using namespace std;

int main()
{
#ifdef _DEBUG
    ifstream cin("data.txt");
#endif // _DEBUG

    long long A, B, C ,res;
    int n,flag;
    cin >> n;
    for (int i = 1; i <= n; ++i)
    {
        cin >> A >> B >> C;
        res = A + B;
        if (A > 0 && B > 0 && res <= 0)flag = 1;//上溢
        else if (A < 0 && B < 0 && res >= 0)flag = 0;//下溢
        else if (res > C)flag = 1;
        else flag = 0;
        cout << "Case #" << i << ((flag) ? (": true") : (": false")) << endl;
    }


#ifdef _DEBUG
    cin.close();
    system("pause");
