Study Notes

Functions in C

Breaking up a program into functions allows for modularity, reusability, and readability, making the code easier to maintain and understand.

Function Naming

The name of a function in C acts as a label that can be called upon to execute the associated block of code.

Function Call Process

When the compiler encounters a function call, it jumps to the function's definition, executes the code inside the function, and then returns to the point where the function was called.

Main Function

The main() function is known as the entry point of a C program, where the program starts execution.

Function Execution

After the called function is executed, control is returned to the calling function, and the program continues executing from where it left off before the function call.
