The Basics of C++
Let’s kick things off with the basics. C++, an extension of the C language, was developed by Bjarne Stroustrup in the late 1970s. Think of it as an enhanced version of C with added features like classes and objects. Its powerful combination of high-level and low-level language features has made it a dominant force in the programming world.
History of C++
C++ has quite the interesting history! It was designed with the aim of adding object-oriented programming features to C, and boy, did it succeed. Over the years, it has undergone several revisions, with enhancements and add-ons contributing to its robustness. From its humble beginnings to its status as a foundational language for modern software development, C++ has come a long way!

Program Code – C++ with Keyword: Understanding Its Use and Scope
#include <iostream>
// Define a class to encapsulate some behaviors.
class Widget {
public:
Widget() {
std::cout << 'Widget created
';
}
// Demonstrate the use of the 'this' pointer
void UpdateValue(int value) {
this->value = value;
std::cout << 'Value updated to ' << this->value << '
';
}
// Static method to show 'this' is not available in static context.
static void StaticMethod() {
// this->value = 10; // Uncommenting this line will cause a compiler error.
std::cout << 'Static method, 'this' pointer is not available
';
}
private:
int value;
};
// Entry point of the program
int main() {
Widget widget;
widget.UpdateValue(42);
Widget::StaticMethod();
return 0;
}
Code Output:
Widget created
Value updated to 42
Static method, 'this' pointer is not available
Code Explanation:
Alrighty! Let’s dive into this piece by piece! So, what we’ve got here is C++ code illustrating the use of C++’s this
keyword within a class, as well as showcasing the limitations of this
within static methods.
At the very start, we’re just pulling in our good old friend <iostream>
to help us with input and output operations.
Moving onto the ‘Widget’ class – pretty sleek name, eh? This class should be as simple as hello world, but we’re using it to pull off some impressive stunts, like showing off how this
works. The constructor is straightforward: whenever you make a new Widget, it prints out ‘Widget created’. That’s kind of part of its charm, like every widget is saying hello to the world when it pops into existence.
Then there’s UpdateValue
. That’s where the this
keyword takes the stage. this
is basically a selfie stick for objects. It’s like the object takes a picture of itself and goes, ‘Yup, that’s me!’ We use this->value
to be expressively clear that the ‘value’ we’re talking about is the one belonging to this particular instance of the object.
Now, our beautiful StaticMethod
is a static function, which means it belongs to the class as a whole, not to any individual object. Think of it as a family recipe rather than someone’s personal cheesecake. Since it’s not tied to a particular object, there’s no this
to refer to. If you uncomment that line inside the static method (which I’ve strategically commented out to prevent an uprising), you would unleash the compiler’s wrath: it’ll throw errors faster than your grandma’s slippers.
We stroll down to main
– every C++ program’s start line. We’re instantiating our Widget class, which makes it print ‘Widget created,’ confirming its existence. Then, we call UpdateValue
, passing 42 as the ultimate answer to life, universe, and everything. Finally, we call StaticMethod
just to prove our point about this
, which yells into the void that this
can’t come to the phone right now.
And that’s the grand tour! The code neatly illustrates some of the nuances of C++’s this
keyword and static methods. As for the expectations, well, it delivered what we predicted, proving once again that code is poetry and predictability is… pretty neat, I suppose? Anyway, hope you enjoyed our little coding adventure! 👩💻✨
