Thread: Mini Game

I have managed to compile the code correctly, however I would like to make the program to instead ask the user again to enter a number rather than close. How should I go around this?

By the way, sorry if it sounds stupid but what does WRT mean?

Use a while(condition). Eg, if you initialize numofbees to 0, the condition could be while(numofbees <= 0).

With Regard To. You can find these if you google "acronym WRT" or whatever, I have to do it pretty often too; recently, "TLA"...

Is this the correct placement for the while loop? If so, I have a problem that when I enter a letter an infinite loop prints out 'How many bees would you like to purchase?' and on the other hand if I enter a number an 'Invalid amount...' prints out everytime.

Examples:
How many bees would you like to purchase?
5
Invalid amount, please try again.
That will be $25, confirm? (Y/N)


OR


How many bees would you like to purchase?
0
Invalid amount, please try again.
How many bees would you like to purchase?
5
Invalid amount, please try again.
That will be $25, confirm? (Y/N)

Code:

#include<stdio.h>


int main()
{
    int numofbees = 0;
    float price = 5;
    char query;


    while(numofbees <= 0){
    printf("How many bees would you like to purchase?\n");
         (!scanf("%u", &numofbees));
    printf("Invalid amount, please try again.\n");
    }


    printf("That will be $%f, confirm? (Y/N)\n", price*numofbees);
        scanf(" %c", &query);


        if(query == 'y'|| query == 'Y') {
            printf("Transaction completed.");
    }
        else {
            printf("Transaction cancelled.");
    }
        getchar();
        getchar();
        return 0;
    }
