There are two ways to execute C++ code on Linux:

Method 1: Using the g++ compiler

The g++ compiler is a command-line tool that can be used to compile and run C++ code. To compile and run a C++ program using the g++ compiler, you can use the following syntax:

g++ -o <executable_file> <source_file>
./<executable_file>

For example, to compile and run a C++ program named my_program.cpp, you would use the following commands:

g++ -o my_program my_program.cpp
./my_program

Method 2: Using an IDE

An IDE (Integrated Development Environment) is a software application that can be used to write, compile, and run C++ code. Some popular IDEs for C++ include:

• Visual Studio Code
• Eclipse
• Code::Blocks

To execute C++ code using an IDE, you can save the C++ code as a file and then compile and run the code from within the IDE.

Here are some additional tips for executing C++ code on Linux:

• Make sure that you have the g++ compiler installed.
• Make sure that the C++ code is saved as a .cpp file.
• Make sure that the C++ code compiles without any errors.
• If you are using an IDE, make sure that the IDE is configured to use the g++ compiler.
