Task:
1) Form a one-dimensional array of integers using a random number generator.
2) Print the resulting array.
3) Remove all elements equal to 0.
4) Add an element with the value M [I-1] +2 after the first even element of the array.
5) Print the resulting array.

Methodical instructions:
1) When performing work, dynamic arrays are used. The arrays themselves are defined, then the user enters the real length of the array and works with the array of the length that he himself specified.
2) When decreasing or increasing the length of an array, it is necessary to create a new array of the required length and fill it with the elements of the old array.

The program gives the correct answer, but for some reason a breakpoint is triggered when clearing the array memory. Please tell me what needs to be done?

Code Program.cpp

# include & lt; iostream & gt;
#include & lt; conio.h & gt;
#include & lt; ctime & gt;
#include "Header.h"
using namespace std;
int main ()
{
  srand (time (NULL)); // We use a random number generator, taking the current time as a base
  cout & lt; & lt; "Enter the length of the array:";
  int t;
  cin & gt; & gt; t;
  int * arr1 = Massiv1 (t);
  for (int i = 0; i & lt; t; i ++) // Print the created array
  {
    cout & lt; & lt; arr1 [i] & lt; & lt; "";
  }
  cout & lt; & lt; endl;
  int p = Massiv2 (arr1, t);
  int * arr2 = Massiv3 (arr1, p, t);
  delete [] arr1; // Clearing the array memory
  int * arr4 = Massiv4 (p, arr2);
  bool elfinded = element (p, arr4);
  if (elfinded == true) // If there is an even element, then increase the array memory by 1
  {
    p ++;
  }
  int m = p;
  delete [] arr2; // Clearing the array memory
  int * arr3 = Massiv5 (m, arr4);
delete [] arr4; // Clearing the array memory
  for (int i = 0; i & lt; m; i ++) // Print the resulting array
  {
    cout & lt; & lt; arr3 [i] & lt; & lt; "";
  }
  cout & lt; & lt; endl;
  delete [] arr3; // Clearing the array memory
  system ("pause");
  return 0;
}

Watching your Massiv5 :

int * arr3 = new int [m]; // Allocate memory for an array

Now –

for (int j = m; j! = i; j--) // Loop for assigning elements to a new array
    {
      arr3 [j + 1] = arr4 [j];

Well, and where are you writing to? What is the item in the account? And where is it located? …

P.S. I was not looking for an error in completing your task in the sense of its meaning 🙂 – this is already on its own …
