This comprehensive course covers the fundamentals and advanced concepts of C programming to build a solid foundation for your programming journey. You’ll learn about essential topics like data types, variables, constants, and C statements, along with deeper explorations of control flow in C, including for loops and conditional statements in C. You’ll also learn about C functions, scope of variables, function arguments, and work with arrays, strings, and pointers in C.

You’ll gain hands-on experience with dynamic memory allocation, stack vs. heap, C standard library, and advanced topics such as binary files, input and output streams, and header files. The course also teaches compiling in C, linking in C, and debugging with tools like GNU debugger (GDB) and gprof for code profiling. By mastering these concepts, you’ll confidently program in C and optimize your code using gcc optimization flags.

# Structure of a function

A function is defined in the following way:

returnType functionName (param1Type param1Name, param2Type param2Name) {
   function_statement1;
   function_statement2;
   return returnVar;
}

This seems rather abstract, but we will see a concrete example in a moment. Here's a breakdown:
- **Return type:** On the first line, we have to begin by declaring what data type the function will return once it finishes. We can define a function that doesn’t return anything by using a data type `void`. 
- **Function name:** The next item is the name of the function, which we get to choose. 
- **Function parameters:** Next, in round brackets, is a list of inputs or parameters that the function expects to see when it is called. Each parameter is declared by listing first its data type followed by its name. 
- **Function body:** Then in the body of the function is the code, which does whatever we want the function to do. 
- **Return statement:** Finally, we have to return a value using a `return` statement if the return type is other than `void`.

## A first example

Here is a more concrete example. Let’s say we want to write a function that writes a message to the screen, “Hello, Paul”:
