I'm passing an array to a constructor. Constructor has two parameters, pointer to int called data and int which is size of an array.
I'm allocation dynamic memory in constructor definition for this array and passing array pointer to this storage.
Last but one step is printing values in array through the pointer which is pointing to the first int value of this array.
The last step is freeing up memory in destructor delete [] data. In this step I got an error message: Debug Assertion Failed! Expression: _CrtlsValidHeapPpinter(block).
I'm very new in C++ so I'm struggling what I did wrong in below program. Could you give me a hint, please?
#include <iostream>
class Test
{
private:
int* data;
int size;
public:
// constructor and destructor
Test(int* d, int s);
~Test();
// few void methods
void display_data(int size)
{
for (int i{ 0 }; i < size; ++i)
{
std::cout << data[i] << " ";
}
std::cout << std::endl;
}
};
Test::Test(int* d, int s)
: data{nullptr}, size(s)
{
data = new int[s];
data = d;
}
Test::~Test()
{
std::cout << "Destructor is freeing memory" << std::endl;
delete[] data;
}
int main()
{
int data_array[5]{ 2,8,6,10,20 };
Test* t1 = new Test(data_array, 5);
t1->display_data(5);
delete t1;
return 0;
}
