Yes we can have parameterized constructor which can also be termed as constructor overloading. Below is a code snippet which shows two constructors for pcdsMaths class one with parameter and one with out.

class pcdsMaths

{

double PI;

// This is the constructor for the maths constant class.

pcdsMaths()

{PI = 3.14;}

pcdsMaths(int pi)

{

PI = pi;

} }
