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.

A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit wi
UkoKoshka [18]

Answer:

The program in Python is as follows:

qty = int(input("Quantity: "))

price = 100 * qty

if qty >1000:

    price = (100 - 0.10 * 100) * qty

print("Cost: "+str(price))

Explanation:

This prompts the user for the quantity

qty = int(input("Quantity: "))

This calculates the price or cost, without discount

price = 100 * qty

This checks if the quantity is greater than 1000

if qty >1000:

If yes, this calculates the price or cost, after discount

    price = (100 - 0.10 * 100) * qty

This prints the calculated cost

print("Cost: "+str(price))
