Answer 5

#include <iostream>
using namespace std;

void init(int inputSize);

int main()
{

int size;
cout << "Введите размер массива: ";
cin >> size;
init(size);
}

void init(int inputSize)
{
int outputSize, i;
outputSize = inputSize % 2 == 0 ? inputSize * 2 : inputSize * 2 - 1;
int* input = new int[inputSize];
int* output = new int[outputSize];
int* ptr, *offsetPtr, *endPtr;
for (ptr = input, i = 0; ptr < &input[inputSize]; ptr++, i++)
{
cout << "a[" << i << "] = ";
cin >> input[i];
}

for (endPtr = &output[outputSize], ptr = input, offsetPtr = output, i = 0; ptr < &input[inputSize]; ptr++, i++)
{
if (i % 2 == 0 && i != 0)
{
offsetPtr = offsetPtr + 2;
}
*offsetPtr = *ptr;

if ((offsetPtr + 2) < endPtr)
{
*(offsetPtr+2) = *ptr;
}
offsetPtr++;
}

for (ptr = input; ptr < &input[inputSize]; ptr++)
{
cout << *ptr;
}
cout << " —> ";
delete[] input;

for (ptr = output; ptr < &output[outputSize]; ptr++)
{
cout <<" " <<*ptr << " ";
}

delete[] output;
}
