How can i get started with a program to add, multiply and sum the square of two 2-dimensional array in c++.
This is strictly for academic purpose, with monday as deadline.
Thanks in anticipation of yooour help.
thanks.

I am assuming that the size of the two arrays is the same
and you are to add the corresponding elements.
you can start with this


#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
int array1[2][2]; //creates a 2*2 matrix or a 2d array. This array 1
int array2[2][2]; //creates a 2*2 matrix or a 2d array. This array 2

//let fill the the two arrayss with some random values. This is up to you to change since I don't know the values you are given
for(int i=0; i<2; i++) //This loops on the rows.
{
for(int j=0; j<2; j++) //This loops on the columns
{
array1[i][j] = i;
array2[i][j] = i + 3;
}
}

//Let get the addition done
for(int i=0; i<2; i++) //This loops on the rows.
{
for(int j=0; j<2; j++) //This loops on the columns
{
cout << array2[i][j] + array1[i][j] << endl;
}
}

cout << endl;
//Let get the subtraction done
for(int i=0; i<2; i++) //This loops on the rows.
{
for(int j=0; j<2; j++) //This loops on the columns
{
cout << array2[i][j] - array1[i][j] << endl;
}
}
cout << endl;
system("PAUSE" ) ;
return EXIT_SUCCESS;
}



One thing you should pick from this and then build on is the ability to read a value at a
specific index

Thanks so much, am grateful.
is it possible to readthe input from a file? as in making use of the #include<fstream>
if possible, how can that be done?
thanks again...
