Question

Alter the Checkbook program from Assignment 5 using C (3 points) o At the top of the file include the following comments Your name -The purpose (core concept found below) of the program . The date created o Create a Check node structure. Include: -Check number (should be an integer) - Date (use type char[ ]) . To Amount Description Pointer to the next Check node o Add functions to: Add a Check to the checkbook. Collect all information for a single check and add it to the checkbook. Call the function to display the values for the check before adding the check. Delete a check from the checkbook. Use the check number to identify the check to be deleted Display the values for a single check. Format the amount for two decimal places Display the values for the entire checkbook, one check at a time o In the main function: Create a checkbook. It should be a linked list. Repeat until the user quits. Give the user these options Add a check. Delete a check. . Display a single check. Display the checkbook .Quit o Compile and run your code o Submit your source code as a plain text file with a .c extension. Make sure it compiles without error before submitting it

Explanation / Answer

#include <stdio.h>

#include <stdlib.h>

// Defines a structure to store Check information

struct Check

{

int checkNumber;

char date[12];

char to[30];

double amount;

char description[100];

// Self reference pointer to point to next Check

struct Check *link;

};// End of structure

// Function to accept a check information and returns it

struct Check inputCheck()

{

// Creates a temporary object of Check

struct Check c;

// Accepts check data

printf("Enter the check details: ");

printf("Check Number: ");

scanf("%d", &c.checkNumber);

printf("Date: ");

scanf("%s", c.date);

printf("Pay To: ");

getchar();

gets(c.to);

printf("Amount: ");

scanf("%lf", &c.amount);

printf("Description: ");

getchar();

gets(c.description);

// Returns the check object

return c;

}// End of function

// Function to display a check information based on the parameter check number

void displayCheck(struct Check *headNode, int checkNo)

// Creates a current node points to head

// PrevNode to store the previous node

struct Check* currentNode = headNode, *prevNode;

// Search the check number to be deleted, keep track of the

// previous node as we need to change 'prevNode->link'

// Loops till end of the list

while (currentNode != NULL)

// Checks if the current node check number is equals to parameter check number

if(currentNode->checkNumber == checkNo)

{

// Set the found status to 1

}// End of function

// Function to accept choice, display menu, and return choice

int menu()

case 1:
