i need some support with my program

[tepelensi]

I am a student and our prefessor has given us an assignment to creat a game in C++, the game is about a player tha moves in a space trying to reach homeland. i have created the 2 dimenson space. i have put the homeland and the palyer. the player moves by inputing number from 1 t 9. my problem is how to delete a blackhole if the players reaches one and the other probelem is that whan i debug it it doesn't execute, this is my program., and how to calculate the curent position of the player and homeland everu time the player makes a step and this can be done by c2 = a2 + b2.

I'm not sure I follow your questions about deleting a black hole; but wouldn't it be just set that location to 0 instead of 2?

As far as the program not executing, I'll need more information: Do you see any errors, for example?

[tepelensi]

the assignment asks me to place 60 black holes rundomly chosed in the universe and each of the black holes should be represented as a "2" so i have set them as o from the beginning. if the player falls in a black hole the player must be returned to his previous position and the black hole should be eliminated form the game.

as for the executing a warning C4700 comes out

[kooth]

When you say eliminated from the game, do you mean it becomes free space into which the player may now pass freely? If so, set the value at the black hole to 0.

[tepelensi]

yes that is the player may pass freely. thanks

[tepelensi]

what does error MSB6003 means?
