This document discusses method overloading in C++, which allows creating multiple functions with the same name as long as they have different parameters. It provides examples of overloading functions based on different data types and number of parameters. The document also includes an example program demonstrating overloading functions to calculate the area of different shapes.

- 4. TOPIC Method overloading in C++
- 5. Method overloading • Method overloading is a feature of C++ that allows us to create multiple functions with the same name, so long as they have different parameters.
- 6. (a) sum (int,int,int); sum (int,int); • Here, the above function can be overloaded. Though data type of arguments in both the functions are similar but number of arguments are different. (b) sum (int,int,int); sum (float,float,float);
- 7. • Function overloading is the process of using the same name for two or more functions. • The secret to overloading is that each redefinition of the function must use either• different types of parameters • different number of parameters.
- 8. Example • • • • • • • • • • • • • • • • • • • • • #include<iostream.h> #include<conio.h> float area(float); //function prototype int area(int); int area(int,int); void main() { int a,l,b; float r; cout<<"Enter the radius of circle"<<endl; cin>>r; cout<<"Enter the side of square"<<endl; cin>>a; cout<<"Enter the length and breadth of rectangle"<<endl; cin>>l>>b; cout<<"Area of circle is "<<area(r)<<endl; cout<<"Area of square is "<<area(a)<<endl; cout<<"Area of rectangle is "<<area(l,b)<<endl; getch(); }
- 9. • • • • • • • • • • • • • • • • • • • • //functions float area(float x) { float area; area=3.14*x*x; return(area); } int area(int x) { int area; area=x*x; return(area); } int area(int x,int y) { int area; area=x*y; return(area);
