help lang c++ help why dynamic allocation and command line

my code:

void print_array(int b[][3]){

int i,j;

cout

for(i=0;i

for(j=0;j

cout

int i, min;

for(i = 2; i>=0 && b[i][from_col]!=0; i--){

disks = i;

}

for(i = 2; i>=0; i--){

if (b[i][to_col]==0){

min = i;

break;

}

}

b[min][to_col] = b[disks][from_col];

b[disks][from_col] = 0;

}

void towers(int disks, int b[][3], int from_col, int to_col, int spare){

Begin by designing these two functions, towers() and print array). To help you out, your towers() function will be recursive with the following prototype: void towers(Int disks, int b[3], Int from_col, int to,col, int spare); Here is an outline of the recursive towers function: If(number of disks is >= 1) Call Towers with (disks-1, b, from_col, spare, to col) Move the disk Print the board Call Towers with (disks-1, b, spare, to col, from col) Dynamically Allocated 2-D array (5 pts) Next, implement this is using a dynamically allocated 2-D array with 3 columns for the 3 posts and N rows for N disks. Get the number of disks from the user as a command-line argument, i.e. towers 5. ntinue to initialize the array with the numbers corresponding to the disks in the first column and Os in all other columns to represent the initial state of the game. You should now see the above example output, given 2 for the number of disks. Remember to change your towers() and print_array) function parameters to accept dynamically allocated arrays, rather th out, your towers() function will be change to the following prototype: an statically allocated.
