We are trying to do our coding in C++.

Here is the sample code:

#include <cstdlib>
#include <iostream>
#include <math.h>
#include <fstream>
#include <istream>
#include <ostream>
using namespace std;

int main(int argc, char *argv[]) {
	std::cout << "Welcome to the QNX Momentics IDE" << std::endl;
	string num;
	cout<<"hello world"<<endl;
	ifstream input;
	ofstream output;
	input.open("numbers.txt");
	output.open("success.txt");
	int z;
	for(int i=0;i<6;i++){
	input>>z;
	cout<<z<<endl;
	}
	double one, two, ans;
	one = 10.0;
	two = 20.35;
	ans = one*two;
	cout<<ans<<" x"<<endl;
	output<<ans<<" victory"<<endl;
	double degree;
	degree=cos(3.1459/4);
	cout<<degree<<endl;
	ans = pow(one,two);
	cout<<ans<<" pow"<<endl;
	ans = sqrt(one);
	cout<<ans<<" sqrt"<<endl;
	output.close();
	return EXIT_SUCCESS;
}

And our file numbers.txt looks like:
1 2 5 7 8 9

And here is the console output:

Welcome to the QNX Momentics IDE
hello world
