Given class "arrayWrapper" defined in the header file wrapper.h show the implementation of method "resize" as it appears in the implementation file ie wrapper.cpp
The resize method is designed to change the size of the dynamic array while maintaining the existing data. It should contain steps to:
Creating a New Array:
A new dynamic array newArr of type T is created with the size specified by newSize
Copying Old Values:A loop iterates through the existing array arr and copies values to the new array newArr The number of values copied is determined by the smaller of the old size and the new size
Deallocating Old Memory; The old array arr is deallocated
Updating Pointers and Size:
The pointer arr is updated to point to the new array
The size variable is updated to reflect the new size
#include
using namespace std;
template
class ArrayWrapper
private:
T arr;
int size;
public:
ArrayWrapperint s : sizes
arr new Tsize;
for int i ; i size; i
arri T; Default initialize the array elements
~ArrayWrapper
delete arr; Proper memory deallocation
void setint index, T value
if index && index size
arrindex value;
T getint index
return arrindex;
void resizeint newSize;
;
