zalisa [80]

Answer:

#include <iostream>

#include <cstdlib>

using namespace std;

int main() {

   int[] array = new int[10];

   int index = 0;

   while(index < array.size()){

           int number = (rand() % 100) + 1;

           for (int i = 0; i < 1; i++) {

               array[index] = number;

               cout<< "Position "<< index << "of the array = "<< number << endl;

               ++index;

           }

     }

}

Explanation:

The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.
