Vector help

Ch1156 (1999)
Ok so in my program i have a vector that outputs the inmate names, its supposed to output 10 or 11 random names but there all the same, why? i dont get compiler errors but if you run it youll see, just choose load, then 1 to virew inmate list, it gives the same exact name 10 times. how do i fix it?
