From lines of input starting with a line containing the numbers of pairs to follows, followed by that number of pairs of integers separated by a space on separate lines from STDIN, output the sum of each pair to STDOUT.

- Sample input with corresponding output

**Input**

5 1 2 10 20 -3 5 100 2 5 5

**Output**

3 30 2 102 10

Modified in order to take in all inputs and then give the output, the original gave the output for each pair immediately.

/*Modified by Abhishek Ghosh, 19th March 2014, Rotterdam*/ #include <iostream> using namespace std; int doStuff(int a, int b) { return a + b; } int main() { int t, **list; cin >> t; list = new int*[t]; for(int j=0; j<t; j++){ list[j] = new int[2]; cin >> list[j][0]>> list[j][1]; } cout << endl; for(int j=0;j<t;j++){ cout << doStuff(list[j][0], list[j][1]) << endl;; } return 0; }

Run as per given input

5 1 2 10 20 -3 5 100 2 5 5 3 30 2 102 10
