Prompts the user to enter another value, until value

[td0g03]

Hello I have a small question. I'm trying to loop a question and scan the number that the user input. The user input must be valid such as that it has to between 1000-3000 range. I tried a small code,but just came to my mind that it would ask twice. I want it to stop if the input is valid and if not ask the question again. Anyone can provide me some tips or help. Thanks.

Example

    while (!(year>3000) && !(year>1000))
        {
        printf("Please enter a year between 1000 to 3000\n");
        scanf("%d\n",&year);
        }
 

Result

Please enter a year between 1000 to 3000
3000
2000

Think about your loop condition. You want to keep getting numbers while year is greater than 3000 or less than 1000. So the loop should execute until the number is between these two - in other words, while year is greater than 1000 AND less than 3000.

Currently, I think you have the loop executing while the user enters a valid number and stopping at an invalid value.

Thanks for the information. I changed the code and understand why, but it still asks to type two numbers if it is is valid or not valid.

Well here is a little update. I been messing around the code.

#include <stdio.h>
 
 
int year;
int whatYear;
 
int main(void)
{
    printf("Please enter a year between 1000 to 3000 first\n");
    scanf("%d\n",&year);
    if(!(year >=1000) || !(year <=3000))
    {
         while(year <1000 || year >3000)
         {
               printf("Please enter a year between 1000 to 3000 second\n");
               scanf("%d\n",&year); 
         }
    }
    else
    year = whatYear;
    printf("herere %d",whatYear);
}
 
 

The result is half right, but it still asks for two input if it valid or not.

Please enter a year between 1000 to 3000 first
1500
1500
herere 0
