How to Run C+ + Programs in Visual Studio Code Terminal for Input

As a budding C+ + programmer, you may face some challenges while running your code, especially when it comes to accepting user inputs. If you've ever found yourself in a situation where you run your program in Visual Studio Code and it waits for input without giving you the option to enter it, you're not alone!

In this guide, we will tackle the issues many new C+ + learners encounter when trying to run their programs in Visual Studio Code, along with practical solutions to enhance your coding experience.

The Problem: Input Issues in Visual Studio Code

While experimenting with a simple program that calculates the number of weeks in a given number of days (including remaining days), you might have noticed that:

When you compile and run the code, the program executes but does not allow for input.

The output window closes immediately after pressing enter when running .exe files directly from the desktop.

This can be frustrating, but don't worry! We'll help you get through it!

Solution: Using Visual Studio Code's Integrated Terminal

Step 1: Access the Integrated Terminal

The first step in resolving the input issue is to use the integrated terminal within Visual Studio Code. This allows you to interact with your program seamlessly. Here’s how to do it:

Open the terminal: You can toggle it using the shortcut Ctrl + ` (the backtick key).

Step 2: Compile and Run Your Program

Once your terminal is open, compilation and execution of your C+ + program can be done in a single step. Follow these commands:

Compile your C+ + code:

Using this integrated terminal will provide a suitable environment for entering input.

Step 3: Preventing Terminal Closure

To ensure that your terminal doesn’t close immediately after running the .exe file, you can modify your C+ + program slightly by adding a line of code.

At the end of your main function, add:

This command will cause the program to wait for the user to press enter before closing, allowing you to read the output after the execution of your code completes.

Sample Code

Here's how your entire C+ + program should look with the added functionality:

Conclusion

Setting up Visual Studio Code for C+ + development can come with its own challenges, particularly regarding user input, but following these steps can help you overcome those hurdles. Remember to use the integrated terminal for your C+ + executions, compile your code correctly, and add cin.get() to prevent the terminal from closing unexpectedly.
