Reading intergers from a file and stroing it in an array using LocalFileSystems.

I have a text file that I have created on the MBed from which I need to read the integers values and store it in an array. The content of the file is single spaced integers, eg

0 1 0 1 0 0 0 1 0 1 0 .....

I want to read this in using file systems and store it in an array. This is the code that I am using but it dies not give me any result.

include the mbed library with this snippet

        #include "mbed.h"

LocalFileSystem local("local");      

//2D array to keep record of the solved maze
int sol[9][9] =
{
{1,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
};

int main()
{       
        FILE *fp2 = fopen("/local/out.txt", "r");        
        for(int i=0;i<9;i++)
        {
            for(int j=0;j<9;j++)
            {
                fscanf(fp2, "%d", &sol[i][j]);
            }
        }
        fclose(fp2);
}

What am I doing wrong?

Where do you define sol?

I had only put the part of the code where I scan the integers from the text file. I have now updated it to include the entire code.
