You may get lastest Microsoft Visual Studio at https://visualstudio.microsoft.com


Step to install Visual Studio

  1. Install Visual Studio Installer
  2. Open Visual Studio Installer
  3. Select "Desktop development with C++" workload
  4. Click Install button

Create first C++ program

  1. Create a new project
  2. Select Empty Project & click Next
  3. Pick a name for your first C++ project & click Next
  4. Right click the "Source Files" in Solution Explorer --> Add --> New Item --> C++ Files --> Add
  5. Write the following code in Visual Studio & save (Don't need to understand the code in this chapter, it will be discuss in later chapters.)
    6. #include <iostream>
using namespace std;

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

  6. Click Run button to execute our first C++ program.
    7. Tada, this will be how our first C++ program looked like. We had finished the set up of C++ develop environment.
