 | >> strcpy(view[place[i].y][place[i].x],"s");//says that the problem is here[/b] That is just a character, not a pointer. same as attempting to do this: [icode] strcpy( view[0][0], "S");[/icode] If all you want to do is replace the single character then use the assignment operator, not strcpy(); [icode] view[place[i].y][place[i].x] = 's';[/icode] |

| | You are getting those errors because you didn't write those functions yet. The three lines just before main() are not functions, they are just [b]prototypes[/b], which tell the compiler about the return value and parameters. You still have to write all the code that makes them do something. |

| | Re: Minesweeper Game >>im a biginner level in Visual C++ version 6.0 That's unfortunate because that old compiler doesn't support c++ very well.
