matrix addition

[idb_study]

Hi all,
I have tried to write a program which can add two matrix.
It is running well....but when I am printing out the resultant matrix it is just showing the address of the resultant elements.

For convenience, I have posted the output also.

Program:-

#include<iostream.h>

int main()
{
        int mat1[3][3];
        int mat2[3][3];
        int i,j;

        cout<<"\n1st Matrix: \n"<<flush;
        for(i=0;i<3;i++)
        {
                for(j=0;j<3;j++)
                {
                        cin>>mat1[i][j];
                }
        }
        cout<<"\n2nd Matrix: \n"<<flush;
        for(i=0;i<3;i++)
        {
                for(j=0;j<3;j++)
                {
                        cin>>mat2[i][j];
                }
        }

         int mat[3][3];
        int k,l;
        cout<<"\nResultant: \n"<<flush;
        for(k=0;k<3;k++)
        {
                for(l=0;l<3;l++)
                {
                        mat[k][l]=(mat1[k][l]+mat2[k][l]);
                        cout<<" "<<mat[l]<<flush;
                }
                cout<<"\n"<<flush;
        }

        return 0;
}

O/p:

1st Matrix:
1 1 1
1 1 1
1 1 1

2nd Matrix:
1 1 1
1 1 1
1 1 1

Resultant:
0xbfe1b810 0xbfe1b81c 0xbfe1b828
0xbfe1b810 0xbfe1b81c 0xbfe1b828
0xbfe1b810 0xbfe1b81c 0xbfe1b828

Why are you flushing so much? The problem is that you can't directly print an array. You have to print from both indices, so

for(k=0;k<3;k++)
{
  for(l=0;l<3;l++)
  {
    mat[k][l]=(mat1[k][l]+mat2[k][l]);
    cout<<" "<<(mat[k][l]);
  }
  cout<<"\n";
}

Also, iostream.h isn't standard. <iostream> is. Which compiler are you using?

[mrnutty]

your problem is your cout statement.

instead of cout<<mat[l];

it should be cout<<mat[l][k];

Thank you very much to all of you.......
sorry for so late reply.....
yes it is working now.......

now the o/p is:-

Resultant:
2 2 2
2 2 2
2 2 2

by the way I'm using gcc compiler
