This is a practice for Online Judge.
The following is an example C++ solution.
#include <iostream>
#include <sstream>
#include <string>
using namespace std;
string _OJINPUT_ =
"5\n"
"8467 -9959\n"
"-3500 -3666\n"
"5724 9169\n"
"-642 1478\n"
"-5536 -3038\n";
int main()
{
#ifndef ONLINE_JUDGE
stringstream ss;cin.rdbuf(ss.rdbuf());ss<<_OJINPUT_;
#endif
int n, a, b;
cin >> n;
for(int i=0; i<n; i++) {
cin >> a >> b;
cout << a << " + " << b << " = " << (a+b) << endl;
}
return 0;
}
The first number is the number of integer pairs.
The following lines are the integer pairs, one pair per line.
For each integer pair, please calculate its sum and print out the result in the "a + b = c" form.
