- It has the same name of the class.
- It must be a public member.
- No Return Values.
- Default constructors are called when constructors are not defined for the classes.
for better understanding about Constructor,
Syntax
class class-name {
Access Specifier :
Member - Variables
Member - Functions

class-name() {
// Constructor code
}
//... other Variables & Functions
}

using namespace std;
class Example {
// Variable Declaration
int a, b;
public:
//Constructor
Example() {
// Assign Values In Constructor
a = 10;
b = 20;
cout << "Im Constructor\n";
}
void Display() {
cout << "Values :" << a << "\t" << b;
}
};
int main() {
Example Object;
// Constructor invoked.
Object.Display();
// Wait For Output Screen
getch();
return 0;
}
Sample Output
Im Constructor
Values :10 20
