Question

void method1(Board b, int numOfRows, int numOfColumns)
{
   Board bb = copyBoard(b, numOfRows, numOfColumns);

}

Board copyBoard(Board* b, int numOfRows, int numOfColumns)
{
   int i;
   int j;
   int x;
   Board bb=createBoard(b->size);
   bb=*b;
   return bb;
}

Board createBoard(int s)
{
Board b;
b.size = s;
b.board = (int*)malloc(sizeof(int) * s);

return b;
}

typedef struct
{
int* board;
int size;
}Board;

When I make a copy of Board in method1() and I try to change the original, the copy gets changed as well.. How can I copy each element and be able to change each one without affecting the other?

Explanation / Answer

bb=*b;

This statement is the culprit. New board is basically pointing to old one. To make new board, copy each property manually to bb.
