Code::Blocks error multiple definition of 'main'
As according to your book Mr. Allain under chapter two i tried to install my first program but it doesnt run. As the default program runs correctly. I created the new file as File>new>empty file and saved as .cpp but the program doesnt run. Ive matched the program from the book and the default one..
What is wrong...what should i do?
What is contained in the main.cpp file? You probably need to remove the Untitled.cpp file from the build.

The main.cpp file contained a default program the format was same as this one except the string of cout function...after i clicked the red error line the main program got erased..
What does that mean to remove from build? Sorry ive never used this type of compiler before I've tried c in turboc..
Right now you have to different files being compiled/built to create your program. Both of these files contain a function named main(), you can only have one main. By removing the Untitled.cpp file you will only have one file, main.cpp. If you use this default file and modify it you should be ready to go.What does that mean to remove from build?
To remove the file from the build right click on the file name, then select remove file from project. In future when you add files you will probably want to give them a name instead of taking the default name "Untitled.cpp".

thankyou jim ..the program runs now..
But how will I create a new program? and compile it without deleting the previous one?.. Also please tell what does this project means..
Thanks...
One project = one program.
One program consists of many source files that are merged together into one file (executable). A project is a way to keep all these files together and merge them into a single file.
So, to create a new program, create a new project. That's all.

Technically you could just create a separate CB target for each main function.
