How to Run C++ Program in Windows 10: A Step-by-Step Guide for Beginners

Running a C++ program on Windows 10 might seem daunting, but it’s actually straightforward. All you need is a C++ compiler and a simple text editor. By following a few basic steps, you will be able to write, compile, and run your first C++ program.

Step-By-Step Tutorial on How to Run C++ Program in Windows 10

By following this guide, you’ll go from writing your first line of C++ code to running it successfully on your Windows 10 machine. Let’s get started!

Step 1: Install a C++ Compiler

First, download and install a C++ compiler like MinGW.

MinGW provides a minimalist development environment for native Microsoft Windows applications. You can download it from the official MinGW website. Make sure to add the path to the compiler to your system’s environment variables.

Step 2: Install a Text Editor

Next, download and install a text editor like Notepad++, Sublime Text, or even Visual Studio Code.

These text editors make writing code easier with features like syntax highlighting. Choose one that you find comfortable to use.

Step 3: Write Your First C++ Program

Open your text editor and type a simple C++ program. Save it with a .cpp extension.

Here’s a basic "Hello, World!" program:

#include 
using namespace std;
int main() {
    cout << "Hello, World!";
    return 0;
}

Save this file as hello.cpp.

Step 4: Open Command Prompt

Press Win + R, type cmd, and hit Enter to open Command Prompt.

The Command Prompt is where you'll compile and run your C++ program. Navigate to the directory where you saved your hello.cpp file.

Step 5: Compile Your Program

In the Command Prompt, type g++ hello.cpp -o hello and press Enter.

This command will compile your C++ code. If everything is correct, it will generate an executable file named hello.

Step 6: Run Your Program

Type hello and press Enter to run your compiled program.

You should see "Hello, World!" printed in the Command Prompt. Congratulations, you've successfully run your first C++ program!

After completing these steps, you should see the output of your C++ program in the Command Prompt. This indicates that your compilation and execution were successful.

Tips for Running C++ Program in Windows 10

• Use Integrated Development Environments (IDEs): Consider using IDEs like Code::Blocks, Visual Studio, or Eclipse, which come with built-in compilers and debuggers.
• Keep Your Compiler Updated: Ensure you are using the latest version of your compiler for the best performance and compatibility.
• Learn Basic Command Prompt Commands: Familiarize yourself with basic commands like cd (change directory) to navigate through your files easily.
• Read Error Messages Carefully: Compilation errors can be cryptic. Take your time to understand error messages to fix issues.
• Take Advantage of Online Resources: Tons of tutorials and forums are available online if you run into problems.
