Project 1: Bank System Using Structure

The document describes a C program to create a menu-driven banking system using structures. The program defines a structure to store customer data including account number, name, and balance. It includes functions to accept customer details, display customer records, search for a customer, deposit money, and withdraw money. The main function initializes an array of customer structures, gets user input for the number of customers, calls the accept function to input details, and runs a menu loop to allow printing records, searching, depositing and withdrawing funds.

Create a structure to specify data of customers in a bank. The data to be stored is:
Account number, Name, Balance in account. Assume maximum of 20 customers
in the bank. Create a function to read all customers details and call it in main.
Your program must be menu driven with following options
1. Print the Account number and name and balance of each customer.
2. Withdraw money
3. Deposit money
4. Search Customer
