Question

In C++:

Write a program that asks the user for an array of X numbers.

Your program moves the largest number all the way to the right, and then shows it to the user.

Hint: Use a loop to swap X times, but only swap if the number on the left is bigger than the number on the right.

Sample Run:

How many numbers would you like to enter? 6

Please enter number 1: 10

Please enter number 2: 8

Please enter number 3: 3

Please enter number 4: 5

Please enter number 5: 2

Please enter number 6: 9

The largest number is: 10

New List: 8, 3, 5, 2, 9, 10

Answer 1

#include <iostream>

using namespace std;

int main() {
   int X, tmp;
   cout<<"How many numbers would you like to enter? ";
   cin>>X;
   
   int* arr = new int(X);
   
   for(int i = 0;i<X;i++){
      cout<<"Please enter number "<<(i+1)<<": ";
      cin>>arr[i];
   }
   
   for(int i = 0;i<X-1;i++){
      if(arr[i] > arr[i+1]){
         tmp = arr[i];
         arr[i] = arr[i+1];
         arr[i+1] = tmp;
      }
   }
   
   cout<<"New List: ";
   for(int i = 0;i<X;i++){
      if(i==0){
         cout<<arr[i];
      }
      else{
         cout<<", "<<arr[i];
      }
   }
   
   return 0;
}
