How to write function inside other function ?

the game is basicly, the computer gets two random cards , and a special card, if the two cards+special card <21 the computer gets extra cards untill the total sum is>21..

then the player gets two random cards , and he can chose if he can chose if he wants extra cards , at the end who has total sum that is closer to 21 but not bigger than 21 wins !

there is more rules , but now i am trieng to solve these problems first.. 

#include <stdio.h>

    next = next * 1103515245 + 12345;
    return ((unsigned int)(next/65536) % 32768) % (high - low + 1) + low;
}

    for (int i = 0; (unsigned int)i < seed; i++) {
