matrix

Hi, I'm newbie in C++. I found a code in assemblylineScduling using dynamic programming.

In part of the codes, I found,

for(i=0; i<numStations; i++)  //numStation=5
		{
			for(j=0; j < numLines; j++)  //numLines 2
			{
				for(k=0; k < numLines; k++)
				{
					
					if(j!=k && i!=numStations-1 )
					{ 
						fin >> transferCost[j][i][k]; 				
					}
					else
					{ 
						transferCost[j][i][k]=0; 
					}
				}
			}
		}

where,
fin, I believe is the .dat input file with the transfer costs as follows,

2 2
3 1
1 2
3 2
4 1

I wonder what is this, fin >> transferCost[j][i][k]; means.

If I'm not wrong, mat[2][3] is: 1 1 1
1 1 1

what will be transferCost[][][] outputs in the above statement? and how about
transferCost[j][i][k]=0;

thanks in advance!

fin >> transferCost[j][i][k];
Read a value from the fin stream into the 3D array transferCost at position j,i,k.
So, if transferCost contains integers, that lines will read 1 integer and store it in the array at position j,i,k.
