Thread: help With arrays

I have been set a task to implement arrays into this code to make its usability better could any help and show me how i could do this

Code:

#include <stdio.h>
#include <stdlib.h> // This library is chosen so functions can be used <stdlib.h>


char ItemChosen = 0;
int Orange = 0;
int Apple = 0;
int Pear = 0;
int Budget = 0;
int RemainingBudget = 0;
char ContinueShopping = 0;


void checkChoice();
void mainMenu();
void setPrices(); // This is the function Decleration for all the functions 
void getBudget();
void thankYou();


void mainMenu() {
    printf("**************************************\n");
    printf("Shop Menu : \n");
    printf("Item:       Price:\n"); 
    printf("O:          %d\n", Orange);   // function initilization for the Menu
    printf("A:          %d\n", Apple);
    printf("P:          %d\n", Pear);
    printf("**************************************\n");
    printf("Please type what item of fruit you would like to purchase : ");
    scanf_s(" %c", &ItemChosen);
    checkChoice();
}
void thankYou() {
    printf("Thanks for shopping with us!\n"); // Function intlization for thank you 
    exit(0);
}


int main() {
    setPrices();
    getBudget();
    mainMenu();
    return 0;
}


void checkChoice() {   // Function Initilization to Check the choice of the fruit chosen
    int success = 0;
    if (ItemChosen == 'A') {
        if (Apple <= Budget) {
            printf("Your purchase has been successful!\n");
            printf("Purchase details\n");
            printf("---------------------------------\n"); 
            printf("Item selected : %c\n", ItemChosen);
            printf("item price : %d\n", Apple);
            RemainingBudget = Budget - Apple;
            printf("Remaining budget : %d\n", RemainingBudget);
            success = 1;
        }
        else { success = 0; }
    }
    else if (ItemChosen == 'P') {
        if (Pear <= Budget)
        {
            printf("Your purchase has been successful!\n");
            printf("Purchase details\n");
            printf("---------------------------------\n");
            printf("Item selected : %c\n", ItemChosen);
            printf("item price : %d\n", Pear);
            RemainingBudget = Budget - Pear;
            printf("Remaining budget : %d\n", RemainingBudget);
            success = 1;


        }
        else { success = 0; }
    }
    else if (ItemChosen == 'O') {
        if (Orange <= Budget) {
            printf("Your purchase has been successful!\n");
            printf("Purchase details\n");
            printf("---------------------------------\n");
            printf("Item selected : %c\n", ItemChosen);

            RemainingBudget = Budget - Orange;
            printf("Remaining budget : %d\n", RemainingBudget);
            success = 1;


        }
        else { success = 0; }
    }
    else {
        printf("Incorrect item (%c) selected.\n", ItemChosen);
        thankYou();
    }


    if (success) {
        Budget = RemainingBudget;
        printf("Do you want to keep shopping (y/n)");
        scanf_s(" %c", &ContinueShopping);
        if (ContinueShopping == 'Y') {
            mainMenu();
            checkChoice(); // function call for both menu and checking the fruit choice
        }
        else if (ContinueShopping == 'N'); {
            thankYou();
        }
    }
    else {
        printf("Error your budget has insufficant funds\n");
    }
}


void setPrices() {
    printf("Please enter the price of Oranges :");
    scanf_s(" %d", &Orange);
    printf("Please enter the price of Apples :"); // Function initlization for the shop keeper to set the fruit price
