Hey, I'm writting a program in C that is supposed to be a simple connect four game. I ran into problems when I tried to assign my array connects to a set value. The compiler gave me the error, Invalid indirection. Heres a little bit of the code where the problem is.
// ask user how big of a board is wanted
printf("\n\nSelect game board size.");
printf("\nEnter number of rows. (min 4, max 9): ");
scanf("%d", &num_rows);
// valid entry check for rows
while((num_rows < 4) || (num_rows > 9))
{
printf("\n\nInvalid entry, Please re-enter row size: ");
scanf("%d", &num_rows);
}
printf("\nEnter number of columns. (min 4, max 9): ");
scanf("%d", &num_cols);
// valid entry check for columns
while((num_cols < 4) || (num_cols > 9))
{
printf("\n\nInvalid entry, Please re-enter row size: ");
scanf("%d", &num_cols);
}
// memory allocation based on user defined board size
ptr2d = (char *)malloc(sizeof(char)*num_cols*num_rows);
board_ptr = ptr2d;
// clean allocated memory and assign a generic filler
for (j = 0; j <= num_cols; j++)
for (i = 0; i <= num_rows; i++)
*board_ptr[i][j] = "*"; //<------problem hereI tried several different ways like:
board_ptr[i][j] ="*"
*(board_ptr[i][j]) ="*"
(*board_ptr[i][j]) ="*"and I'm using Borland C++ builder 5.
