Program Code – C++ When to Use This: Understanding Its Role in Code

#include <iostream>
#include <memory>

class Example {
    int _value;

public:
    Example(int value) : _value(value) {
        std::cout << 'Resource ' << _value << ' acquired.' << std::endl;
    }
    ~Example() {
        std::cout << 'Resource ' << _value << ' released.' << std::endl;
    }
    void PrintValue() const { std::cout << 'The value is ' << _value << std::endl; }
};

class UseThisExample {
private:
    std::unique_ptr<Example> _example;
    
public:
    UseThisExample(int value) : _example(new Example(value)) {
        // The unique_ptr _example now owns the resource.
    }
    
    void DoSomething() {
        std::cout << 'Doing something with resource.' << std::endl;
        _example->PrintValue();
        // Here we can use 'this' to refer to the object's member.
        this->_example->PrintValue();
    }
};

int main() {
    UseThisExample example(42);
    example.DoSomething();

    // No need for manual clean-up, RAII takes care of object destruction.
    return 0;
}

Code Output:

Resource 42 acquired.
Doing something with resource.
The value is 42
The value is 42
Resource 42 released.

Code Explanation:

Let’s break down the code:

• Firstly, we have included iostream for input and output operations and memory for smart pointers.
• We’ve got a simple class Example which simulates a resource. Upon creation (in the constructor), it announces that it has acquired a resource (simulated by an int value) and upon destruction (in the destructor), it releases the resource.
• The PrintValue method simply outputs the value of the resource to demonstrate a class method that might utilize the resource.

Moving into the UseThisExample class:

• It holds a std::unique_ptr<Example> to manage the lifetime of an Example object. This smart pointer automatically cleans up the resource when the UseThisExample object is destroyed; thus upholding the principles of Resource Acquisition Is Initialization (RAII).
• The constructor of UseThisExample initializes the _example unique pointer with a new instance of Example, transferring ownership of the new resource to the smart pointer.
• In the DoSomething method, we use the this pointer explicitly to invoke PrintValue on our _example member. This is somewhat redundant here, as we can call _example->PrintValue() without this, because there’s no ambiguity.

Lastly, in main:

• We instantiate UseThisExample with the value 42, then call DoSomething on it.
• Upon exiting main, the UseThisExample destructor is called, which in turn triggers the Example destructor via the unique_ptr, and the resource is released without any manual clean-up code.

This example succinctly demonstrates the use of this when there’s no necessity because member variables aren’t shadowed by local variables. The example also shows how RAII simplifies resource management in C++, particularly when paired with smart pointers.
