Dear all,

I m a newbie in C. When do the questions in "C Programming for Absolute Beginners" (MICHAEL VINE, 2008)

When talked about structure programming, there is a question.

Write A function that prints an ATM menu—it receives no
parameters and returns no value.

Void displaymenu()

Int display_balance();
Int deposit_funds();
Int transfer_funds();
Int withdraw_funds();
Int get_available_balance();
Int compare_balance_to_request();
Int update_account();
Int disperse_funds();
Int reject_request();
Int print_receipt();
Int verify_ample_funds_exist();
Int initiate_mechanical_process();
Int update_bank_records();
Int atm_lv1() = 0;
Int atm_lv2() =0;
Int atm_lv3() =0;

Any incorrect or improvement needed?

It's completely broken. I'm fairly confident you didn't attempt to compile that code, much less run it.
