Write C++ code

General steps to execute the program are as follows:

  • Launch Text editor like Notepad, Notepad++, etc.

// C++ Header file
#include 
using namespace std;
// Entry Point : main routine.
int main()
{
 cout << "Hello, World!"; // print message
 return 0;
}

Compile C++ Program

Open the Command prompt and issue the following command to compile the code.

\> g++ main.cpp

If there are no errors in the code a.exe executable file would generate.

Execute C++ Program

Now, type ‘a.exe’ to run the C++ program. You would be able to see ‘ Hello, World !’ printed on the console.

Compile C++ Program Command Prompt
