In this lab you will learn about the concept of Normal Forms for refining your database design. You will then apply the normaliz

ation rules: 1NF, 2NF and 3NF to enhance your database design. Lab Steps: Read about the Normal Forms in your textbook, chapter 14, pages 474 to 483. Check the learning materials on Normal Forms under the Learning Materials folder of Week 5. Apply the Normalization rules to your database design. Describe in words how 1NF, 2NF and 3NF apply to your design/database schema. Apply all the modifications that you made due to applying NF rules to your actual database in the DBMS (MS SQL Server). Put your explanation for how 1NF, 2NF and 3NF apply to your database in a Word document OR PowerPoint presentation.

AutoSum is a feature in Microsoft Excel which involves you as the user being able to input some sort of formula and for it to apply to all selected cells. It works in many different ways. For example, it has the ability to auto fill so that it fills the cells with numbers from 1-100. Or days of the week, or months of the year. If you were creating a Gantt chart for project management, you would want to auto fill the consecutive days of which you want the project to run for.

Write a program that generates two 3x3 matrices, A and B, withrandom values in the range [1, 100] and calculates the expression½
Alex

Answer:

#include <bits/stdc++.h>

using namespace std;

int main() {

int A[3][3],B[3][3],res[3][3],i,j;

srand(time(0));//for seed.

for(i=0;i<3;i++)

{

   for(j=0;j<3;j++)

{

   int val=rand()%100+1;//generating random values in range 1 to 100.

   int val2=rand()%100+1;

   A[i][j]=val;

   B[i][j]=val2;

}

cout<<endl;

}

for(i=0;i<3;i++)

{

   for(j=0;j<3;j++)

   {

       res[i][j]=0.5*A[i][j]+3*B[i][j];//storing the result in matrix res.

   }

}

cout<<"Matrix A is"<<endl;

for(i=0;i<3;i++)

{

   for(j=0;j<3;j++)

   {

       cout<<A[i][j]<<" ";//printing matrix A..

   }

   cout<<endl;

}

cout<<"Matrix B is"<<endl;

for(i=0;i<3;i++)

{

   for(j=0;j<3;j++)

   {

       cout<<B[i][j]<<" ";//printing matrix B..

   }

   cout<<endl;

}

cout<<"The result is"<<endl;

for(i=0;i<3;i++)

{

   for(j=0;j<3;j++)

   {

       cout<<res[i][j]<<" ";//printing the result..

   }

   cout<<endl;

}

return 0;

}

Output:-

Matrix A is

13 95 83  

88 7 14  

24 22 100  

Matrix B is

11 13 95  

48 35 20  

68 100 18  

The result is

39.5 86.5 326.5  

188 108.5 67  

216 311 104  

Explanation:

I have created 2 matrices A and B and storing random numbers int the matrices A and B.Then after that storing the result in res matrix of type double to store decimal values also.Then printing the res matrix.
