exiting a while loop with a negative integer

I want the user to enter few different numbers numbers, and after that to test each number separately.

Also I need to terminate the program ONLY when the number 0 entered.

This is the beginning of my code:

int userInput;
printf("please enter some numbers: \n");
while ((scanf("%d", &userInput)) == 1)
{
    ...
}

How can I keep getting input from the user until 0 is entered?

Answer 1

while ((scanf("%d", &userInput) == 1) && (userInput != 0))
{
   ...
}
