Not getting the output I want - c++

Question

I am trying to write a c++ program to read a txt file containing data (122X300 matrix - tab delimited matrix) into my code and get it to display. The following is the code I wrote after referring extensively to google and many similar questions on this site. On running the code, I do not get any errors, however it does give me huge list of numbers which I cant seem to make any sense of. The following is the code: Any help would be great. I do not know where I am going wrong. Thanks.
DID some changes after considering the comment below by #ZekeMarsh, the problem now is that my text data is like:
Data Matrix Snapshot
The output I am getting is this:
Output of Code
The row counter does not move over to the next row,instead continues in the same row after incrementation....No idea why. The code modified is as follows:
#include <stdio.h>
#include <iostream>
#include <fstream>
#include <string>
#include <conio.h>
using namespace std;
int main(){
int HEIGHT = 3;
int WIDTH = 2;
int array_req[HEIGHT][WIDTH];
string userinputprompt, filename;
userinputprompt = "Data Filename: ";
cout<<userinputprompt<<endl;
getline(cin,filename);
ifstream inputfile;
inputfile.open(filename.c_str());
for(int i=0; i<HEIGHT; i++)
{
for(int j=0; j<WIDTH; j++)
{
/*if(!(inputfile>>array_req[i][j]))
{
cerr<<"Error";
break;
}
else if(!inputfile) // its error.. , can use a cerr here...
{
cerr<<"Error";
break;
}
else*/
inputfile>>array_req[i][j];
cout<<i<<","<<j<<"-->"<<array_req[i][j]<<endl;
}
/* This is not needed, read above comment
else
{
inputfile >> array_req[i][j];
}*/
}
for(int p=0; p<HEIGHT; p++)
{
for(int q=0; q<WIDTH; q++)
{
cout<<array_req[p][q]<<" ";
}
cout<<"\n";
}
inputfile.close();
getchar();
return 0;
}
.
EDITED CODE - The output array is a null matrix. Please help. What is wrong in the code ..compiles correctly. Trying to read line by line using getline and stringstream based on a lot of examples I read here..still not working.
#include <stdio.h>
#include <iostream>
#include <fstream>
#include <string>
#include <conio.h>
#include <sstream>
#include <stdlib.h>
const int HEIGHT = 3;
const int WIDTH = 4;
const int BUFFSIZE = 10000;
using namespace std;
int main(){
int array_req [HEIGHT][WIDTH];
char buff[BUFFSIZE];
string userinputprompt, filename;
userinputprompt = "COLORDATA FILENAME: ";
cout<<userinputprompt<<endl;
getline(cin,filename);
ifstream inputfile;
stringstream ss;
inputfile.open(filename.c_str());
for (int i=0; i<HEIGHT; i++)
{
inputfile.getline(buff,BUFFSIZE,'\n');
ss<<buff;
for(int j=0;j<WIDTH; j++)
{
ss.getline(buff,1000,'\n');
array_req[i][j]=atoi(buff);
}
ss<<"";
ss.clear();
}
for(int p=0; p<HEIGHT; p++)
{
for(int q=0; q<WIDTH; q++)
{
cout<<array_req[p][q]<<" ";
}
cout<<"\n";
}
inputfile.close();
getchar();
return 0;
}

First of all during the printing of your array, you are not delimiting your data with anything which will result in a line of numbers. You should add delimiter and line breaks.
Second and most importantly: you try printing the full value of the array while it has not been filled up yet. I believe you meant to put the printing outside of the loop that works with your variable i . Now you are printing garbage in the places where the array was not filled yet.
Edit: Here is only the reading part as I believe that is only what you are looking for:
for (int i = 0; i < HEIGHT; ++i)
{
std::string tmpString;
std::getline(inputfile, tmpString);
std::stringstream ss(tmpString);
for(int j=0;j < WIDTH; ++j)
{
ss >> array_req[i][j];
}
}
