Program that requests input of an integer number

Help, I'm a C noob, and need help writing this program:

The program will request input of an integer number. if the entered number matches a specific number(an ID number) it will continue. If the entered number does not match the specific number, it has to request a new number. If a "q" is entered it will quit.

I have the basics of it down, I'm just wondering if and where to put a while loop in there, and I've come up with something kind of like this:

#include <stdio.h>

int main()
{
int idnumber;
printf("Enter your student ID number:");
scanf("&#37;d", &idnumber);
if(idnumber==30922419)
{
printf("Correct: Please continue.")
}

}

I know it's flawed, but I've been working on it for days. The main problem that i am having is getting the program to request the number, and what to do from there.

I would appreciate any help.

Assuming it is something like "if the entered password is wrong, request password again";

remove the if statement and

Code:

---

while(idnumber!=30922419)
{   
    printf("Wrong! wrong! Enter Again:");
    scanf("%d", &idnumber);
}

ok, i got it to work, all i need now is to know how to make it quit when a "q" is entered.

Code:

---

#include <stdio.h>

int main()
{
int idnumber;
printf("Enter your student ID number:");
scanf("%d", &idnumber);
while(idnumber!=30922419)
{printf("Wrong number. Please enter correct number:");
scanf("%d", &idnumber);
}
}

check within while loop...if idnumber == q....then break out of loop.......

It will not work

You need to change the input - for example use fgets to read all the string typed by the user
Then check - if the fist char of the string is 'q' - exit
Otherwise use sscanf or strtol to convert string to number

since you are supposed to quit when user enters 'q', and you are reading int ids also, i will say, use a char array for input, check for 'q', otherwise convert it to int, and check for id.

edit: clash of the times! ditto timing! :D i love cboard!

If it's just an ID number, then there's absolutely no need to convert it into an integer, as I expect you'll never actually use it for calculations (ID number - 32 * 5.0 / 9 doesn't really make sense, unless you actually _REALLY_ want to know how many celcius degrees your fahrenheit ID number makes). So a string comparison would be fine.
