Yes, It is called Constructor Overloading.ģ.
Can we have more than one constructor in a class?. It is used to initialize the various data elements of different objects with different values when they are created. Example e = Example(0, 50) // Explicit call The constructors can be called explicitly or implicitly. The normal way of object declaration may not work. When an object is declared in a parameterized constructor, the initial values have to be passed as arguments to the constructor function. Okay, and he will give a new marker for you. And this is what a parameterized constructor is! Then the third one you go to a shop and say I want a marker like this(a physical marker on your hand). So in this case you have given the parameters. So you are mentioning this and he will give you that marker. And this is what a default constructor is! The second method you go to a shop and say I want a marker a red in color and XYZ brand. 
So when we said just I want a marker so whatever the frequently sold marker is there in the market or in his shop he will simply hand over that. So just saying give me a marker mean that you did not set which brand name and which color, you didn’t mention anything just say you want a marker.
When you want to buy a marker, what are the options? The first one you go to a shop and say give me a marker. Suppose you went to a shop to buy a marker. Let us understand the types of constructors in C++ by taking a real-world example.
