    Help for a beginner

    Hi, I am brand new to programming and I am just getting to grips with C language. However, I am stuck! I have been ask to do a program which expects me to allow a customer to selected a piece of fruit from a shopkeepers menu. However, I am stuck on when the customer chooses the fruit (so enters a char data type) how I can then get the program to recognise the price of the fruit (As an integer) which the shopkeeper has entered to then be able to put this into a decision to then compare with the customers budget.

    Post your code.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Code:
    #include <stdio.h>
    
    
    int main()
    {
        int Orange;
        int Apple;
        int Pear;
        int Budget;
        char ItemChosen;
    
    
        printf("Please enter the price of oranges :");
        scanf_s("%d", &Orange);
        printf("Please enter the price of Apples :");
        scanf_s("%d", &Apple);
        printf("Please enter the price of Pears :");
        scanf_s("%d", &Pear);
    
    
        printf("**************************************\n");
        printf("Hello and welcome to my fruit shop\n");
        printf("Please enter your budget : ");
        scanf_s("%d", &Budget);
    
    
        printf("**************************************\n");
        printf("Shop Menu : \n");
        printf("Item:       Price:\n");
        printf("O:          %d\n", Orange);
        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, 1);
        
    
    
            // I am not sure how to get the integer from the fruit the customer selects 
        
             if (  <= Budget)
        {
            printf("Your purchase has been successful\n");
            printf("Purchase details\n");
            printf("---------------------------------\n");
            printf("Item selected : %c\n", ItemChosen);
            printf("item price : %d", );
        }
        else if (  > Budget);
        {
            printf("Error Your budget has insignificant funds\n");
            printf("Thanks for shopping with us!");
        }
        return 0;
    if there is any other faults in the code please make me aware

    Try something like
    Code:
    if ( ItemChosen == 'O' ) {
      if ( Orange <= budget ) {
      }
    }

    Would this piece of code need to be done for All the fruits with multiple decisions?
