What is the role of main() in C?
a) First function executed
b) Handles memory allocation
c) Initializes variables
d) Declares all variables
Answer:
a) First function executed
Explanation:
The main() function serves as the entry point for any C program. When a program is executed, the runtime environment calls the main() function first, starting the sequence of commands defined within it. It is essential to every C program, as it dictates the flow of execution and is where most of the program’s logic is executed.
Understanding the importance of the main() function is crucial for beginners and advanced programmers alike, as it is the foundation upon which the structure of a C program is built.
