A function that will read the data file name and its contents. The first row of the data file will have two entries: the number of rows in the matrix followed by the number of columns in the matrix, the remainder of the file will contain the (real, floating point) matrix elements, row by row. The function should return the number of rows and columns in the matrix as well as the matrix.

I'm stuck on how to scan in the data. I feel like I would be able to do the rest if I got some help on the first function. This is my attempt:

double function1(void)

{

char filename[20];

double matrix[5][5], row, col, rowcol[2];

int status, i, j;

FILE* infile;

printf("Enter the file name: ");

scanf_s(" %s", &filename);

infile = fopen(filename, "r");

//error check filename

while (infile == NULL)

{

printf(" The file doesn't exist. ");

printf("Enter the file name: ");

scanf_s(" %s", filename);

}

//read data in

fscanf_s(infile, "%lf %lf", &row, &col);

for (i = 0; i

{

j = 0; // what is =0 here

for (j = 0; j

{

fscanf_s(infile, "%lf", &matrix[i][j]);

printf("matrix[%d][%d] = %lf", i, j, matrix[i][j]);

}

}

fclose(infile);

rowcol[0] = row;

rowcol[1] = col;

return(rowcol[2]);

}
