You can compile and run your programs using Dev-C++. This IDE is very easy to use. There are several useful features included in the free trial version. You can even run your projects in MS-DOS mode. The program will not close once it has finished. This feature is especially helpful if you're programming in C++, as you can open the C++ compiler in the command line. But if you want to compile and execute your programs in a command line environment, you'll need to install additional tools such as a VS Code or a Windows Visual Studio development environment.

Before you can begin writing code, you need to install the MinGW compiler. After you've installed the compiler, you can start the Dev C++ IDE. You'll need about 70 megabytes for the installation. Once you have the installation completed, select the language and location where you want to install it. Once you've built the program, click on "New Document" to open it and begin editing your code.

In Dev-C++, you can create projects by selecting File > New > Project. There you can also create multiple source files. For a single source file, you don't need to create a separate project. You can use the same project name as the source file, such as Console. For a second project, use C++. For the third one, you can create a console application. To create a new console application, choose File > New > Source File.
