Is the error from line 111 of you code? You are trying to write to inventory[10] which is illegal because you declared inventory as inventory[10] . This means that the valid range for the subscript is 0-9.

i can see that there is some thing wrong:

inventory[10] = "Empty";

while :

const int SIZE = 10;    
string inventory[SIZE] = {0};

so max is 9
