2D array help...

i need to write a program as follows:

Write a program that prompts the user to enter three positive integers representing the number of rows, the number of columns of a grid, and the number of mines hidden in the grid, the program then calls the following function:

void Minesweeper(int nRows, int nColumns, int nMines )

The function Minesweeper( ) prints a grid of nRows x nColumns of 0's and 1's. A 0 represents a square that has no mine and a 1 represents a square that has a mine. The parameter nMines represents the number of mines.

Hint: Store the 0's and 1's in a two dimensional array first then print that array.

i have started it, but i have no idea on where to to go about with this. i will paste my code down below, but i know it wont help much.

i just need someone to point me to the right direction on how to solve it. i know i need to store the values into an array, but i'm a little confused on how to do that with variables? and i assume that my task is to generate the user-defined number of mines into random parts of the array- i dont even know where i would go about trying to figuring that one out.

here's my code:

Code:

---

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
using namespace std;

void minesweeper(int numbers_r, int numbers_c, int numbers_m);

int main ()
{
int numbers_r, numbers_c, numbers_m;
//int mineArray[numbers_r][numbers_c];
cout<<"Enter the number of rows: ";
cin>>numbers_r;
cout<<"Enter the number of columns: ";
cin>>numbers_c;
cout<<"Enter the number of mines: ";
cin>>numbers_m;
minesweeper(numbers_r, numbers_c, numbers_m);
return 0;
}

void minesweeper(int nRows, int nColumns, int nMines)
{
char mines_chr= '1';
char not_mines_chr= '0';
if (nMines>0)
n_not_mines=(nRows*nColumns)-nMines;

int mineArray[nRows][nColumns];
for (int i=0; i<nRows; i++)
{
for(int j=0; j<nColumns; j++)
mineArray[i][j]= n_not_mines;
cout<<setw(5)<<mineArray[i][j];
}
}

Let me answer that with your own source code:

Code:

---

int mineArray[nRows][nColumns];

---

This will work with a modern compiler.

Use rand(). Think about how you would put mines in a field with pencil and paper.

Code:

---

1) Pick a random spot
2) If there is already a mine there, pick another spot
3) If there isn't, put a mine in that spot
4) Go back to 1
