To read the file stream and write to a two-dimensional array?

Have the source text file input.txt you need a thread to read all the contents of the file and throw in a two-dimensional array. I tried to do so but I have only read the first line
char line [5][20];
int count=0;
fstream fIn;"input.txt",ios::in);
