Question

Consider a Dynamic Array declared inside the code using int* z = new int[10]; . How we will free the memory after we are done with the z array?

Answer 1

#include <iostream>
using namespace std;

int main()
{
    int* z = new int[10];//  use of the 'new'  operator is allocating memory for arrays.
    // some array operations
    z[5]=10;
    cerr<< z[5];
    // operator delete [] to free the allocated memory array
    delete[] z;
    return 0;
}
