Taking a file's content (each character) and putting them into a 2D array.

[Hunkofsteel]

Basically, I want to be able to take the content of a file and put them into a 2D array. Each line would correspond with each row. Problem is, I have no idea how to do this. I don't even know if this is possible.

Right now, all I know is that I have to use get.line

After passing it into an array, I want to be able to check the value of all the arrays, and if they equal to a value, replace them. (Like take all the W from the array and change them to S)

 #include <iostream>
#include <fstream>

using namespace std;

void main (void)

//char map_three (char map[20][20])
{

	ifstream inData;
	inData.open ("file1.txt");  //open file

        while (!inData.eof()) { //read from input files
             getline( inData, data);
             //not sure what to do here.




}

	int rows = 20; //create array using pointers and double pointer
	int ** maze = new int * [rows];

	int cols =60;
	for (int r = 0; r < rows; r ++)
	{
		maze[r] = new int [cols];
	}

}

It would help if you show sample file contents, the file format is not obvious from the description.
For example, if you're reading every character from the line, your data structure could be a simple vector of strings:

#include <iostream>
#include <fstream>
#include <algorithm>
#include <vector>
#include <string>

int main()
{
    std::vector<std::string> maze;
    std::ifstream inData("file1.txt");  //open file

    std::string line;
    while ( getline(inData, line) ) //read until eof
        maze.push_back(line);

    // replace every 'W' with 'S'
    for(auto& line: maze)
        std::replace(line.begin(), line.end(), 'W', 'S');

    // output
    for(auto& line: maze)
        std::cout << line << '\n';
}

but if you have, for example, space-separacted characters (e.g ". . . S ." rather than "....S..", then conversion of line into the string to be pushed back would be a little different.

Can't the arrays take in space-bars? I just need each character to go in their seperate array.

This is what I want to pass in, with all the underlines to be changed to spacebars and the Ws changed to another ASCII character. This is a map for a simple game.

And in your code,
for(auto& line: maze)
I don't understand this. I thought for is a loop? And what is auto and &?

[Cubbi]

That sample I posted works on that input file.

for(auto& line: maze)
I don't understand this. I thought for is a loop?

It is a loop, yes. if your compiler is too old to handle this syntax, the equivalent 1998 loop would be

for(std::vector<std::string>::iterator i = maze.begin; i != maze.end(); ++i)
        std::replace(i->begin(), i->end(), 'W', 'S');
