How to run cpp file in cmd
So, linker takes your object file and combines it with other object files from the package and then converts it to an executable file. The compiler comes in here and compiles the source code to object files.
Create and edit .cpp file in command line
Yes just make a folder like this:
Then create the text file and write it with vim (or nano if you find vim hard):
VS Code | Compile and Run in C++, Pass the executable file to be run and press enter. Type the required input, each separated by space and press enter. The required output shall be displayed in a new-line of the command line as shown below. Input/Output through text files: Create two text files input.txt and output.txt. Make sure input.txt …

Run cpp file without compiling
The process of a C/C++ program when you make one till you run it:
- You write the program’s source code.
- The compiler comes in here and compiles the source code to object files. Note: Remember that the program cannot be executed at this stage. It’s only an object file. You’d know this if you have worked on bigger size programs, but if you haven’t here is how it works. Remember using those header files in your programs? These header files just tell the compiler that there are some things that are not defined in your program. They are somewhere else. So your compile compiles the program to the object file leaving out things that have a prototype (which is in the header files).
- This is a very important point. Here a program called ‘linker’ comes into play. What linker does is to take all the object files created by compiler and combines them into one. Say for example your compiler created a single object file. Now, you’re using math library or anything from standard library. The compiler-linker package (often called only compiler) comes with object files for these standard library definitions. So, linker takes your object file and combines it with other object files from the package and then converts it to an executable file. This is the file that you can run. Nothing else is runnable directly.
To run source code the process is explained already, we have to use the g++. Now
What I understand from your question is that you want to know if a program can be run once it’s compiled and linked properly (hence an executable has been generated). Answer to that would be yes.
Alternatively, may sound strange, there is an interpreter I know called Cling that can be of use to bypass the compilation of C++ program. After all C++ is generally seen as a compiled language. However, any programming language can be implemented as a compiler or as an interpreter and Cling happens to be an interactive C++ interpreter based on LLVM and Clang. Take a thorough look at this
Compiling with g++, g++ hello.cpp . This compiles and links hello.cpp to produce a default target executable file a.out in present working directory. To run this program, type ./a.out where ./ represents present working directory and a.out is the executable target file../a.out . g++ -S file_name is used to only compile the …

How to Run C and C++ Program in CMD
In this article I will tell you how to run C and C++ program in CMD.
CMD or Command Prompt is a command line interpreter in Windows operating system. Running C and C++ programs using command prompt is useful in case you don’t have an IDE installed in your system.
Things you will need
You must have a C or C++ compiler like GCC, Visual C++, etc. already installed in your system. If you don’t have any, you can easily get them by searching on Google.
How to Run C and C++ Program in CMD
1.Before running programs we must set the path of compiler. So, first right click on Computer icon and go to Properties option.
2. Click on Advance system settings and then Environment Variables.
3. A new window will open, there click on New button. In Variable name filed enter path and in Variable value filed enter the path of the bin folder of compiler.
4. You can find the path of bin folder by going to the directory where you have installed the compiler.
5. After that click all OK buttons to save the information.
6. Press Win+R keys to open Run. Type cmd and press enter to open command prompt.
7. Now change the directory to where you have saved your C or C++ program file. Lets say you have saved the program on Desktop then type cd desktop and press enter.
8. Now for compiling the program type gcc filename. Here filename is the name of the program file. I have used gcc command because I have installed GCC compiler in my system. The command will change if you are using any other compiler, like for Turbo C++ it will be tcc, for Borland C++ it will be bcc and so on.
9. For running the program just type the name of the source file without .c or .cpp extension and press enter.
10. If you have followed steps properly then you can see the output.
