Reading from a data file to 2D array. No output. C++ - c++

Question

I am new to programming and c++. I am working on an assignment which requires me to read data from a data file and store it into a 2D array. Every line in the text file is in the following format(data type is int)
XXXX XX XX XX XX ...(and so on)
The four digit number is actually student ID and is to be stored in a separate 1D array. I have done this part and I don't have any issues. Now the rest 2 digit numbers are to be stored in a 2D array with 4 columns and X rows, where X is the number of lines in the data file.
I have written the following code to try to read into the file. It gives no error and compiles correctly but when I try to print the 2D array, using cout, I don't get anything. Nothing. Please look at the following code and try to help me.
I am new to stackoverflow and programming so please forgive me if the code is not formatted correctly or is not as per the tradition.

Answer 1

Your else-Statement is wrong, there are some brackets missing (now you always reset c to zero)
