Hello After a while of lurking I finally registered so this is my first post. I'm making a Black Jack game and am having a problem with delete[]. Anyway I'll show you my code first: The Black Jack Game: (Ive left out everything I felt was unnessicerry) int BlackJack(int money){ int *deck; deck = Shuffle(); delete[] deck; cout << "Thats All right now Folks" << endl; return money; } int* Shuffle(void){ int i; //Loop counter int *deck = new int[52]; for(i = 0; i < 52; i++) { deck[i] = i; //cout << deck[i] << endl; } //theres actually 52 cards in a deck so 0-51 == 52 ints //Later I will / the card num by 13 to find out suit ////////////////////// SHUFFLE DECK //////////////////////////////////////////// //I want to get 2 rand nums between 0-51 //Then flip those 2 nums in the deck int num1; int num2; int Old1; int Old2; for(i = 0; i < 52; i++) { num1 = rand()%52; num2 = rand()%52; if(num1 == num2) { --i; } else { //cout << num1 << " " << num2 << endl; Old1 = deck[num1]; Old2 = deck[num2]; deck[num1] = Old2; deck[num2] = Old1; } } //Check the shuffling //for(i = 0; i < 52; i++) //{ // cout << i << ": " << deck[i] << endl; //} deck[52] = 0; return deck; } When I step through the code I get this error on the "delete[] deck;" line. error: Debug Error! Program: (program name) DAMAGE: after Normal block(#73) at 0x003016F0 (Press Retry to debug the application) The funny thing is is if I take out the delete[] line it runs fine, but I don't feel right leaving delete[] out I've searched around here and on msdn and got nothing so if any of you can help I would be verry thankful. NOTE: I fixed it by changing int *deck = new int[51] to int *deck = new int[52] in Shuffle(), but why did that work?!?!? p.s. !@#@!#$$!!! Now it's not working again. Same error. I'm really confused now. [edited by - DrunkenBastard on August 7, 2002 2:40:44 AM] [edited by - DrunkenBastard on August 7, 2002 2:41:22 AM] [edited by - DrunkenBastard on August 7, 2002 3:13:12 AM]
