#171 World in C++

The clichéd starting point, in C++.

Notes

Demonstrating the C++ standard input/output library to write some text on the screen.

#include <iostream>

using namespace std;

int main() {
  cout << "Hello!" << endl;
  return 0;
}

Build and run the example hello.cpp:

$ make
c++ -std=c++17 -g -Wall -O3    hello.cpp   -o hello
./hello
Hello!
