The document outlines the basic steps for creating and executing a C program, which includes compiling source code and running the executable. It defines source code as a high-level language file saved with a '.c' extension and explains the compilation process that translates this code to low-level language while checking for errors. Additionally, it provides shortcut keys for compiling, executing, and checking results in Turbo C.

3. 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.

Steps to create source code?
- Open a text editor.
- Create New File.
- Type the program instructions.
- Save the file with “.c” extension.

5. Compiling Source Code
4
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

6. Executing/Running Executable Code
4
- 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

7. Checking Result
4
- 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
