On the screenshot is the result after I typed a negative integer. How do I ignore the negative integers on bottles' result? Help pls.

The positive & zero results are just fine, but the negatives are not finishing the do-while loop to prompt the user another digits for minutes. What is wrong here please?

TIA

  • You've had an answer. :) But keep in mind that the spec specifically says that you can assume that only positive integers will be given, so there is no need for any checking loop.

The idea is to use a DO-WHILE loop as you do in your program but we will use it when ordering an integer with the function get_int():

do 
{
    printf("Enter an integer"
    minutes = get_int()
}
while(minutes < 0)

The loop will be repeated while minutes are less than zero, the rest of the program should not go inside a loop
