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.

Create a method called randomValues that uses a while loop to generate a random number between 1-25 until the value 10 is genera

ahrayia [7]

Answer:

The method in Java is as follows:

public static void randomValues(){

Random r = new Random();

int sentinel = 10;

int randNum = r.nextInt(24) + 1;

while(randNum!=sentinel){

System.out.print(randNum+" ");

randNum = r.nextInt(24) + 1;

}

System.out.print(sentinel);

}

Explanation:

This defines the method

public static void randomValues(){

This creates a random object, r

Random r = new Random();

This sets the sentinel value to 0

int sentinel = 10;

This generates a random number

int randNum = r.nextInt(24) + 1;

This loop is repeated until the the random number is 10

while(randNum!=sentinel){

Print the generated number

System.out.print(randNum+" ");

Generated another random number

randNum = r.nextInt(24) + 1; }

Print the sentinel (i.e. 10)

System.out.print(sentinel);

}
