Creating Source Code What is source code?
- Source Code is the file which contains programming code in high level language. - To create source code, we need a text editor to write the program. - In C programming language every source code file must be saved with “.c” extension. 2

ALT + F9 Compiling Source Code What is Compilation?
- Compilation is the process of translating the code from high level language to low level language. - But before translation compiler check for the errors. If there are any errors it does not translate, simply returns list of errors. - To compile a C source code in Turbo C, we use shortcut key ALT + F9 4
6
Executing/Running Executable Code
- After completing the compilation the compiler generates an executable file with .exe extension. - We need to execute this executable file to generate result - To run a C executable code in Turbo C, we use shortcut key CTRL + F9 4
7
Checking Result - After execution the result is placed in the window called User Screen. We need to open that user screen to check result - To open user screen in Turbo C, we use shortcut key ALT + F5 4
