USACO JAN07LEVEL1 Problem 'names' Analysis

by Rob Kolstad

Swapping names is not so hard in C++; just read the names themselves into different variables then print them, as Bruce Merry did:

#include <string>
#include <fstream>

using namespace std;

int main() {
    ifstream in ("names.in");
    ofstream out ("names.out");
    string first, last;
    in >> first >> last;
    out << last << ", " << first << "\n";
    return 0;
}
