Trying to validate an entry, New to C

The program compiles, but when I enter the number 22 it falls out of the while loop. I want to tell the operator that they entered an incorrect value and please try again and again.... if neccessary. I am not sure where my logic is flawed.

Thank You for lookin at this.

Code:

---


 /*
 *Loop till valid entry with message
 */
#include <stdio.h> 

int main(void)

{
        double value;  // stores numerical value 
        int exitvalue;    //declatarations
        exitvalue=0;    //initialize variable

        do
        {       
        //  ask for and get numeric value
        printf("Please enter numeric value between 1 and 10:  \n");
        scanf("%lf",  &value );

            if (value< 1 ||  value>10) // check to see if value less than 1 OR  greater than 10
                {
                exitvalue=0;
                printf("Invalid entry please try again\n"); // value is outside of acceptance range - loop again
                }
          else
              {
              exitvalue=1;  //value is in acceptance range - exit while loop
              }

        }
        while (exitvalue==1);  //exit when exitvalue is equal to 1
       
        printf("condition met  \n");
                                       
return (0);
}

So you want to enter 22 and in the last printf to have "an anwer that 22 is not between 1 and 10"??
output:

vasileios@vasileios-laptop:~/desktop$ ./a.out
Please enter numeric value between 1 and 10:
22
Invalid entry please try again
condition met

what exactly do you want to have??

You have your exit values backwards. You should be staying in the loop as long as it's not right, not exiting.

The values I am setting right now are to test and make sure it works.
if I enter a 5 it prompts me to enter another number. If I enter a number above 10
it tells me "invalid entry please try again" then tells me "condition is met" meaning it exited the while loop.

I am confused as to the exit values since I am setting them.

I want a value to be vaild as designated by my if statement before exiting the loop

Code:

---

do
{       
    if (value< 1 ||  value>10) // check to see if value less than 1 OR  greater than 10
    {
        exitvalue=0;
    }
    else
    {
        exitvalue=1;  //value is in acceptance range - exit while loop
    }
} while (exitvalue==1);  //exit when exitvalue is equal to 1

Your comments do not match what you say they're doing.

"Your comments do not match what you say they're doing."

Please enlighten me....

What part of "while this is one, keep looping" is confusing? You set it to 0, which makes it NOT ONE, which makes your loop stop.

Sorry, Brain dead.... Changed the ==1 to 0 it works fine.
Thanks
