Question

I am pretty new to C and I have got a problem here in C:
I want to write a program which reads a txt file and writes the content it a char[50][50].

To read the file I used fopen but I have no idea how to write this into the array. What is a good way to solve this?

EDIT: @BLUEPIXY’s answer is significantly better than this approach.

@Hidde’s code adapted for this specific example:

// Include the standard input / output files.
// We'll need these for opening our file
#include <stdio.h>


int main ()
{
    // A pointer to point to the memory containing the file data:
    FILE * pFile;

    // Open the file itself:
    pFile=fopen ("250.txt","r");
    // Check that we opened the file successfully:
    if (pFile==NULL)
    {
        perror ("Error opening file");
    }
    else
    {
        // The file is open so we can read its contents.
        // Lets just assume its got 50*50=250 chars in.

        // Initialise an array to hold our results:
        char array[50][50];
        int row, col;
        for (row = 0; row < 50; row++)
        {
            for (col = 0; col < 50; col++)
            {
                // Store the next char from our file in our array:
                array[row][col] = fgetc (pFile);
            }
        }

        // Close the file
        fclose (pFile);

        // Demonstrate that we've succeeded:
        for (row = 0; row < 50; row++)
        {
            for (col = 0; col < 50; col++)
            {
                printf("%c", array[row][col]);
            }
            printf("\n");
        }
    }
    // Return 0 indictaes success
    return 0;
}

Really there should be some code to check that the input file meets your expectations, otherwise strange things may happen.
