i ve created two dimensional array inside a function, i want to return that array, and pass it somewhere to other function..
char *createBoard( ){
char board[16][10];
int j =0;int i = 0;
for(i=0; i<16;i++){
for( j=0;j<10;j++){
board[i][j]=(char)201;
}
}
return board;
}
but this keeps giving me error
I would really recommend using STL vector<> or boost/multi_array containers for this.
If you must use arrays, then I would recommend using a typedef to define the array.
typedef char[16][10] TBoard;
You could also return
char**
...but then you would need to typecast it to the correct size in order to index it correctly. C++ does not support dynamic multiple dimension arrays.
Also as others have suggested you can't return an object on the stack (i.e., local variable)
Don't return pointer to a local variable, as other mentioned. If I were forced to do what you want to achieve, first I'd go for std::vector. Since you haven't learnt std::vector, here is another way:
void createBoard(char board[16][10])
{
int j =0;int i = 0;
for(i=0; i<16;i++){
for( j=0;j<10;j++){
board[i][j]=(char)201;
}
}
}
