Thread: inialisation for the while loop

Hi folks.

Is there a problem with nbr in the below sample code from my C book not being initialised? I am thinking that because of this, it could actually contain 99, so the program could actually stop before the user enters any values?

Thanks in advance.

Code:

int value[5];
int ctr = 0;
int nbr;

while(ctr < 5 && nbr != 99)
{
    puts("Enter a number, 99 to quit");
    scanf("%d", &nbr);
    value[ctr] = nbr;
    ctr++;
}
