ehinmero: Dear Nairalander please what's the latest about AsUP Strike its been over three weeks that we've been at home.

blenyo11: 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

olyjosh: There is nothing like database design like they meant- but database is been design, model as a structure of tables of data grouped together called relational database.(They are being achieved in form of tables)

I think you don't have to argue with those guys since you said you want to learn it cos they are both speaking from practical/programming perspective.

Anyway, What type of database did want to learn?
Did you know anything about STANDARD QUERY LANGUAGE?(basis of most database querying languages)
What did you intend to use it for?

Though I don't know what you wanted to use it for but I will advice you to learn MYSQL or ORACLE, since Access among other are going out of use.

For low level database go for Microsoft Access or Excel (lol).

Knowlegde is power.
