Unique Pointer Example 3

unique_ptr_e3.cpp

#include <iostream>
#include <memory>

using namespace std;

class SomeBigObject{
public:
    float data[1000];
    
    void something() {
        // just something
    }

    void someOtherThing(){
        // just some other thing
    }
};

void ProcessBigObject(const SomeBigObject& o){
    // do some crazy processing with o
}

int main(){
    // create a unique pointer
    // unique_ptr<SomeBigObject> pBigObject(new SomeBigObject()); // you can also do it this way
    unique_ptr<SomeBigObject> pBigObject = make_unique<SomeBigObject>(); // but this is preferred

    // use it like just any other pointer
    pBigObject->something();
    pBigObject->someOtherThing();

    ProcessBigObject(*pBigObject); // pass it as a reference

    // pBigObject is automatically freed when the main function block ends
    // no need to call delete explicitly
    
    return 0;
