For creating and executing a C++ program, one must follow four important steps.
1. Creating Source code :
Creating includes typing and editing the valid C++ code as per the rules followed by the C++ Compiler.
2. Saving source code with extension .cpp After typing, the source code should be saved with the extension .cpp
3. Compilation
This is an important step in constructing a program. In compilation, compiler links the library files with the source code and verifies each and every line of code. If any mistake or error is found, it will inform you to make corrections. If there are no errors, it translates the source code into machine readable object file with an extension .obj
4. Execution
Execution is the final step of construction of a C++ Program. In this stage, the object file becomes an executable file with extension .exe. Once the program becomes an executable file, the program has an independent existence. This means, you can run your application without the help of any compiler or IDE.
