Example on function overloading

Open Window forms Application Project Place a Button Code in GD

 Class Test

{

Public void print ( float x)

{

Message. Box. Show (“From float :” + X);

}

Public void Print (double X)

{

Message. Box. Show (“From double:” + X);

}

Public void Print (decimal X)

{

Message. Box. Show (“From decimal:” + X);

}

}

//test Code for button1_click Test t = new Test ();

Print (4.0) ;//

//t. Print (4); error

Print (4f);//float

Print (4m);//decimal

Print (4d);//double
