hello guys i seriously need ur help....i made a code to take readings from text file for my matrix....the problem is when i output the pattern is all rong...e.g
my input:
1 2 3
3 4 5
2 4 5
expected output:
1 2 3 0 0 0
3 4 5 0 0 0
2 4 5 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0

  #include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream infile("input.txt");
ofstream outfile ("output.txt");
int m1[6][6]={0};
int i=0, j=0;
for (i=0; i<6; i++)
{
	for (j=0; j<6; j++)
	{infile>>m1[i][j];


	outfile<<m1[i][j]<<" ";
	} outfile<<endl;
}


return 0;
}

for (j=0; j<6; j++)

change to for (j=0; j<3; j++)

okay so what if i have multiple input of a square matrix

well it really depends on what you are trying to achieve. If you wish to store the second matrix next to the first, in the array then you will have to offset your start and end positions like so.

for (j=3; j<6; j++)
	{infile>>m1[i][j];


You could then make the third one

for (i=3; i<6; i++)
{
	for (j=0; j<3; j++)
	{infile>>m1[i][j];


	outfile<<m1[i][j]<<" ";
	} outfile<<endl;
}


And the forth one

for (i=3; i<6; i++)
{
	for (j=3; j<6; j++)
	{infile>>m1[i][j];


	outfile<<m1[i][j]<<" ";
	} outfile<<endl;
}


To eliminate the redundancy of the for loops you could create a counter variable and either an if else block or a switch case block to set i and j respective to the required part of the array you intend to input.

A question you should ask yourself is do I require to have them all in the same array?
