Question

Write a program to prompt the user to display the following menu:

Sort             Matrix                   Quit

• If the user selects ‘S’ or ‘s’, then prompt the user to ask how many numbers you wish to read. Then based on that fill out the elements of one dimensional array with integer numbers. Then sort the numbers and print the original and sorted numbers in ascending order side by side.

How many numbers: 6

Original numbers:                     Sorted numbers

34                                                                         2         

55                                                           11

2                                                              34

89                                                            55

78                                                            78

11                                                            89

Do you want to quit? Q

• If the user selects ‘M’ or ‘m, prompt the user to read an elements of two dimensional array of 2 x 2. Then, find the transpose of matric A and then add the transposed matrix to the original matrix and save the results into matrix C. Print the elements of matrices A, A-transposed , and C.

Do you want to quit? Q

If the user enters ‘Q’ or ‘’, your program should terminate the program.

Answer 1

Below is the complete C++ code. If you face any difficulty while understanding the code, Please let me know in the comments.

Code:

#include <iostream>
#include <bits/stdc++.h>

using namespace std;

int main() {
char ch;
cout << "Menu:\n Sort: s or S\n Matrix: m or M\n Quit: q or Q" << endl;
cin >> ch ;
  
if(ch == 's' || ch == 'S') {
int n;
cout << "How many numbers:";
cin >> n ;
  
int origArr[n];
int sortArr[n];
  
for(int i=0;i<n;i++) {
cin >> origArr[i];
sortArr[i] = origArr[i];
}
  
sort(sortArr, sortArr + n );
  
cout << "Original numbers" << " Sorted numbers" << endl;
for(int i=0;i<n;i++)
cout << origArr[i] << " " << sortArr[i] << endl ;
  
}else if(ch == 'm' || ch == 'M') {
  
int A[2][2];
cout << "Enter the elements of matrix M:\n";

for(int i=0; i<2; i++)
for(int j=0; j<2; j++)
cin >> A[i][j];
  
int A_transposed[2][2];
for (int i = 0; i < 2; i++)
for (int j = 0; j < 2; j++)
A_transposed[i][j] = A[j][i];
  
int C[2][2];
for (int i = 0; i < 2; i++)
for (int j = 0; j < 2; j++)
C[i][j] = A[i][j] + A_transposed[i][j];
  
// Print matrix A
cout << "\nMatrix A:\n";
for(int i=0;i<2;i++){
for(int j=0;j<2;j++)
cout << A[i][j] << " ";
cout << "\n";
}
  
// Print matrix A-transposed
cout << "\nA-Transposed matrix:\n";
for(int i=0;i<2;i++){
for(int j=0;j<2;j++)
cout << A_transposed[i][j] << " ";
cout << "\n";
}
  
// Print matrix C
cout << "\nMatrix C:\n";
for(int i=0;i<2;i++){
for(int j=0;j<2;j++)
cout << C[i][j] << " ";
cout << "\n";
}
} else if(ch == 'q' || ch == 'Q') {
char ch;
cout << "Do you want to quit? Q\n" ;
cin >> ch;
  
if(ch == 'Q')
return 0;
}

return 0;
}
