What is the purpose of breaking up a program into functions in C?
What is the purpose of breaking up a program into functions in C?
- To reduce the efficiency of the program
- To restrict the flow of information between different parts of the program
- To enable writing independent segments of code to perform well-defined tasks (correct)
- To make the program more complex and difficult to understand
What does the name of a function in C act as?
What does the name of a function in C act as?
- An interface to the outside world for information transfer and result transmission (correct)
- A placeholder for the function's documentation
- A label for the function's position in the program
- A restriction on the function's access to other parts of the program

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.
