Question

needs to be done in C++

Q6. Coding Question (you must code this problem and submit via Blackboard):

Keep everything as Integers.

Row and Column Numbering starts at 1.

Equation for each Cell :   Coll = (Row * Col * 10)

Using Nested Loops display the following exactly as it is shown below:

                                 Columns %

Brand         1           2         3          4          

    A            10         20       30       40     

    B            20         40        60       80      

    C            30         60        90     120     

   D            40         80      120     160     

Answer 1

#include <iostream>

using namespace std;

int main()
{
    int Col,Row,Coll,n=5;
    cout<<"\t\tColumns%"<<endl;   //To display Columns%
    cout<<"Brand\t";             //display Brand
    for(Row=1;Row<=n;Row++)
    cout<<Row<<"\t";            //To print 1,2...4 in 2nd row
    cout<<endl;
    for(Row=1;Row<=n;Row++)    //Row value varies from 1 to 4
    {
        cout<<char('A'+(Row-1))<<"\t"; //To display A,B,C,D.
      //ascii value of A is added to (Row-1) and converts to char.
        for(Col=1;Col<=n;Col++)    //Col value varies from 1 to 4
        {
            Coll=(Row * Col * 10);    //calculate cell value using given formuala
            cout<<Coll<<"\t";
        }
        cout<<endl;
    }

    return 0;
}

Working of nested loop, n=4

for(Row=1;Row<=n;Row++)    //Row value varies from 1 to 4

    { for(Col=1;Col<=n;Col++)    //Col value varies from 1 to 4

        {

            Coll=(Row * Col * 10);    //calculate cell value using given formuala

            }

     }

Row=1

ROW	1	1	1	1
COLUMN	1	2	3	4
CELL VALUE	1*1*10=10	1*2*10=20	1*3*10=30	1*4*10=40

ROW=2

ROW	2	2	2	2
COLUMN	1	2	3	4
CELL VALUE	2*1*10=20	2*2*10=40	2*3*10=60	2*4*10=80

ROW=3

ROW	3	3	3	3
COLUMN	1	2	3	4
CELL VALUE	3*1*10=30	3*2*10=60	3*3*10=90	3*4*10=120

ROW=4

ROW	4	4	4	4
COLUMN	1	2	3	4
CELL VALUE	4*1*10=40	4*2*10=80	4*3*10=120	4*4*10=160
