C++ Syntax and Comments

Statements end with ;, blocks use { }, and C++ is case-sensitive. using namespace std; lets you skip the std:: prefix.

ExampleC++

#include <iostream>
using namespace std;

int main() {
  // single-line comment
  cout << "One" << endl;
  /* multi-line
     comment */
  cout << "Two " << "Three" << "\n";
  return 0;
}

Output

One
Two Three
