Hi all,
I have a very large file so I want to dynamically allocate the memory of a 2d array and then fill it up with the file inputs. Before i used malloc to make the 2d array, everything worked fine (I was using a practice small .txt). However, i believe something is going wrong with my fscanf part and I don't know why.
FILE *fr; // declare the file pointer
int x, y; // Dimensions of .txt data, 3 columsn and 330770 inputs;
//DYNAMIC MEMORY ALLOCATION FOR data ARRAY
double** data;
data = (double **) malloc(330770 * sizeof(double*));
for (int h = 0; h < 330770; h++)
data[h] = (double*) malloc(3*sizeof(double));
//determines the placement of the finalData
fr = fopen ("c:\\blahblah.txt", "r"); /* reads the file */
for(x=0; x<12; x++){ // loops through the rows
y = 0; //starts at first column during each row loop
while(fscanf(fr,"%L", &data[x][y++]) > 0); // loops through the columns until each row ends.
}
cout<<data[0][0];
Currently, it is displaying 1.7317e-307 instead of displaying the correct number of 20010929. Thankyou!
