I am trying to print a random character from an array by using rand()

Hello all I want to write a program to randomly choose a character from an array, so far I have come up with this code. I get an Error message help...Thread 1: EXC_BAD_ACCESS (code=1, address=0x48) at the last printf()

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(){
    int lower = 1, upper = 6;
    int test;
    srand((unsigned int)time(0));

    char*  placeArray[]={"Renti","Mosxato","Tavros","Kallithea","Petralona","Thisio"};
    int i, num;
    for (i=0;i<6;i++){
        num=(rand() % (upper - lower + 1)) + lower;
        test=(int)num;
        printf("%d ",num);
        printf("%s\n",placeArray[num]);

    }
    return 0;
}
