Question

COP 2220 Into programming in C(Answer in C, not C++). The question is:

Please write the algorithm for a AppStore programming assignment. The details of the assignment, a sample algorithm, and its outline, are located below. Make the algorithm at least half a page, easy to read, and to understand, how it works. I just want the algorithm, not the programming code, I have that. I only need the ALGORITHM. Thanks for helping me out, I apprieciate it, have a pleasant day.

SAMPLE ALGORITHM:

(FOR A DIFFERENT PROGRAMMING ASSIGNMENT)

Sample Algorithm for Program 1
1. Display instructions
2. Ask user for number of games to play
3. For each game
a. get a letter from file
b. Play one game
i. While still has guesses
ii. Get guess from player
iii. Compare guess to letter from file
iv. If guess is correct, return 1
v. Else increase counter
vi. Return 0 if 5 guesses incorrect
c. check for win or lose

Assignment purpose: User defined functions, pointers, Menu driven program
A Company needs to create software for their new line of phone Applications. Customers will have the
opportunity to purchase the Apps using the following cash amounts: (1) - $20.00, (2) - $10.00, (3) - $5.00
(4) - $2.00, (5) - $1.00

You must have at least 7 user defined functions:
// Displays the list of apps available
//prompts for the user’s selection and sets the value of the selection
void AppMenu(char *appChoicePtr);
//sets the cost of the item based on appChoice
void GetCost(char appChoice, double *appCostPtr);
//Displays the menu for the user to input money - gets user input amounts
//compares the int codes and updates the balance amount
void MoneyMenu(double *balancePtr, double appCost);
//compares the amount the user has in their balance to the price of app selected.
//It returns 1 if the amount is enough to cover the cost, 0 if there is not enough.
int Enough(double balance, double appCost);
//uses MoneyMenu function to display and collect dollar amounts from the user
//uses Enough function to keep comparing the balance amount to the appcost.
void GetMoney(double *balancePtr, double appCost);
//calculates the amount of leftover from balance after the purchase is made
void GetChange(double *balancePtr, double appCost);
//Asks the user if they want to buy another app
void Again(char *quitPtr);

SAMPLE OUTPUT:

PROGRAM OUTLINE:

//Displays the list of apps available
//Prompts for the user’s selection and sets the value of the selection

Answer 1

Algorithm: 1) Display Balance 2) Display menu instruction 2) Ask user to enter app choice 3) Get item cost 4) if item cost greater then balance 3) Repeat until balance greater than or equal to app cost a) Display Money menu b) ask user to deposit money c) add deposit money to balance d) check balance is enough to by app i) if yes deduct app cost from balance ii) else continue step 3 4) ask user for another transaction 1) if yes then repeat step 2 2) else quit the program

Note: in question you said that you have the code so i am not giving the code
