When we run the program who initiates the program execution by calling the main function?

The correct answer is (b) main() function. Program execution starts and ends at this in case of C programming language. At the beginning of all C programs, the execution control directly goes to main(). This function is called by the operating system itself while the user is running the program.

When the program executes the execution always begins with the first statement in?

Flow of execution. In order to ensure that a function is defined before its first use, you have to know the order in which statements are executed, which is called the flow of execution. Execution always begins at the first statement of the program. Statements are executed one at a time, in order from top to bottom.

Why Every program starts with main function?

In many programming languages, the main function is where a program starts its execution. It enables high-level organization of the program’s functionality, and typically has access to the command arguments given to the program when it was executed.

How many times main () function can be invoked in a program?

In a C program if there are more than one functional present then one of these functional must be main( ) because program execution always begins with main( ). There is no limit on the number of functions that might be present in a C program.

How to execute a function before and after main() in C?

With GCC family of C compilers, we can mark some functions to execute before and after main(). So some startup code can be executed before main() starts, and some cleanup code can be executed after main() ends. For example, in the following program, myStartupFun() is called before main() and myCleanupFun() is called after main().

Can startup and cleanup functions be executed before main()?

So some startup code can be executed before main () starts, and some cleanup code can be executed after main () ends. For example, in the following program, myStartupFun () is called before main () and myCleanupFun () is called after main ().

What is the main function of a program?
