.CPP files are C++ Source files, which contain C++ programming source codes. Here is a sample .CPP C++ Source file, mapInsert.cpp, containing some simple C++ statements:

#include <map>
#include <iostream>
using namespace std;

class Data {
  Data(int val = 0) { mVal = val; }
  int getVal() const { return mVal; }
  void setVal(int val) {mVal = val; }

  int mVal;

int main(int argc, char** argv) {
  map<int, Data> dataMap;
  pair<map<int, Data>::iterator, bool> ret;

  ret = dataMap.insert(make_pair(1, Data(4)));
  if (ret.second) {
    cout << "Insert succeeded!\n";
  } else {
    cout << "Insert failed!\n";
  ret = dataMap.insert(make_pair(1, Data(6)));
  if (ret.second) {
    cout << "Insert succeeded!\n";
  } else {
    cout << "Insert failed!\n";
  return (0);
