Write the definition of a function reverse, whose first parameter is an array of integers and whose second parameter is the numb
GrogVix [38]

Answer:

The c++ function for reversing an array is given. The function is declared void since it returns no value.

void reverse( int arr[], int len )

{

   int temp[len];

   for( int k = 0; k < len; k++ )

   {

       temp[k] = arr[k];

   }

   for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )

   {

           arr[k] = temp[j];

    }

}

Explanation:

The reverse function uses another array to reverse the elements of the original array.

An integer array is declared, temp[len], having the same length as the input array.

int temp[len];

To begin with, the elements of the input array are copied in the temp array.

for(int k = 0; k < len; k++ )

{

       temp[k] = arr[k];

}

Next, the elements of the input array are given new value.

The temp array, in reverse order, is copied into the input array.

for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )

{

           arr[k] = temp[j];

}

The above for loop makes use of two variables simultaneously.

While the array, arr is proceeding from first element to the next, the array temp begins with the last element and goes down to the previous element.

Now, the input array, arr, contains the elements in reverse order.

The complete program is given.

#include <iostream>

using namespace std;  

 

void reverse( int arr[], int len );

void reverse( int arr[], int len )

{

   int temp[len];

   

   for(int k = 0; k < len; k++ )

   {

       temp[k] = arr[k];

   }

   

   for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )

   {

           arr[k] = temp[j];

   }

   

}

int main()  

{

   int len = 5;    

   int arri[len];    

   for( int l = 0; l < len; l++ )

   {

       arri[l] = l;

   }

   

   reverse( arri, len );    

   return 0;

}

The teachers began to follow a new type of teaching, and the academics began to follow a special method for communique, education as well as for helping the students understand the concepts.

Though, after the 1980s the personal computer came into being in schools and colleges. Since then numerous versions of PC have originated in the marketplace as well as mobiles tracked by Smartphones, and now nearly 100% of people in the US have smartphones. Virtual reality, augmented reality, AI, Machine learning. etc. has cemented the way for the virtual classrooms. Also, each subject is now up with fruits and not just-food. The consequence is such a delightful setup of the Virtual schoolrooms in the entire US, and all over the ecosphere. The projectors, VR devices, AI applications for education, online classroom facility, Electronic version of chalkboards, and in fact everything is no sophisticated, and it is making not only teaching easy but learning as well. And the result is, students are ending up with better results, and teachers seem to be happier and more relaxed. And that is making school management satisfied as well.
