Question

C++

This week, you are to create two separate programs, first using a simple array and the second using a 2D-array (matrix). [Part 1] Write a program that accepts exactly ten (10) integer numbers from the user and stores them in an array. In a separate for-loop, the program then goes through the elements in the array to print back: (i) The sum of the 10 numbers, (ii) the minimum value from the 10 numbers, and (iii) the maximum value from the 10 numbers. [Part 2] Write a program that creates two 2x2 matrices, A and B, and then adds them together to create a third matrix, C. Create these matrices using 2x2 integer arrays and prompt the user to input values to populate the A and B matrices. Then, compute and print back the summation matrix, C. Do print the matrix using a format similar to what we did during lecture.

Answer 1

Part 1 code

#include<bits/stdc++.h>
using namespace std;
int main()
{
   int arr[10];
   cout<<"Enter 10 Integers "<<endl;
   for(int i=0;i<10;i++)
   {
       cin>>arr[i];
   }
   int sum=0;
   int maximum=INT_MIN;
   int minimum=INT_MAX;
   for(int i=0;i<10;i++)
   {
       sum+=arr[i];
       if(maximum<arr[i])
       {
           maximum=arr[i];
       }
       if(minimum>arr[i])
       {
           minimum=arr[i];
       }
   }
   cout<<"Sum of 10 integers are "<<sum<<endl;
   cout<<"Minimum value from 10 integers "<<minimum<<endl;
   cout<<"Maximum value from 10 integers "<<maximum<<endl;
}

part 2 code

#include<bits/stdc++.h>
using namespace std;
int main()
{
   int A[2][2],B[2][2],C[2][2];
   cout<<"\n";
   cout<<"Elements are entered row-wise \n"<<endl;
   cout<<"Enter the values in first matrix \n "<<endl;
   for(int i=0;i<2;i++)
   {
       for(int j=0;j<2;j++)
       {
           cin>>A[i][j];
       }
   }
   cout<<"The values of matrix is A \n"<<endl;
   for(int i=0;i<2;i++)
   {
       for(int j=0;j<2;j++)
       {
           cout<<A[i][j]<<" ";
       }
       cout<<endl;
   }
   cout<<"Enter the values in second matrix \n "<<endl;
   for(int i=0;i<2;i++)
   {
       for(int j=0;j<2;j++)
       {
           cin>>B[i][j];
       }
   }
   cout<<"The values of matrix is B \n"<<endl;
   for(int i=0;i<2;i++)
   {
       for(int j=0;j<2;j++)
       {
           cout<<B[i][j]<<" ";
       }
       cout<<endl;
   }
   cout<<"The values of matrix C is \n "<<endl;
   for(int i=0;i<2;i++)
   {
       for(int j=0;j<2;j++)
       {
           C[i][j]=A[i][j]+B[i][j];
       }
   }
   for(int i=0;i<2;i++)
   {
       for(int j=0;j<2;j++)
       {
           cout<<C[i][j]<<" ";
       }
       cout<<endl;
   }  
}
