#### Aim :

To write a C++ program to implement the concept of Function Overloading

#### Function Overloading in C++

- You can have multiple definitions for the same function name in the same scope.
- The definition of the function must differ from each other by the types and/or the number of arguments in the argument list.
- You cannot overload function declarations that differ only by return type.

#### Algorithm:

- Start the program.
- Create the class with variables and functions.
- In the main (), declare the variables.
- Use Volume () function to find the volume of cylinder, cube and rectangle.
- Define the volume () function with necessary arguments for calculation.
- The values that are passed inside the function call will be matched with the definition part and appropriate calculations are done.
- All three volumes are displayed accordingly by display() function.
- Stop the program.

**Program:**

#include<iostream> using namespace std; double area (int r) { return 3.14*r*r; } int area(int b,int h) { return b*h; } void area(int h,int b,float* res) { *res=0.5*h*b; } int main() { int choice,i=0; while(i<1) { cout<<"\n1.CIRCLE\n2.RECTANGLE\n3.TRIANGLE\n4.EXIT\n"; cin>>choice; if(choice==1) { int r; cout<<"ENTER THE RADIUS\n"; cin>>r; cout<<"AREA OF CIRCLE: "<<area(r)<<endl; } else if(choice==2) { int b,h; cout<<"ENTER THE HEIGHT AND BREADTH\n"; cin>>b>>h; cout<<"AREA OF RECTANGLE: "<<area(b,h)<<endl; } else if(choice==3) { int b,h; float result; cout<<"ENTER THE HEIGHT AND BREADTH\n"; cin>>b>>h; area(h,b,&result ); cout<<"AREA OF TRIANGLE:"<<result<<endl; } else { i=5; cout<<"PROGRAM EXITED\n"; } } return 0; }

**Execution**:

**Execution**:

Input 1 3 2 5 4 3 6 2 4 Output 1.CIRCLE 2.RECTANGLE 3.TRIANGLE 4.EXIT ENTER THE RADIUS AREA OF CIRCLE: 28.26 1.CIRCLE 2.RECTANGLE 3.TRIANGLE 4.EXIT ENTER THE HEIGHT AND BREADTH AREA OF RECTANGLE: 20 1.CIRCLE 2.RECTANGLE 3.TRIANGLE 4.EXIT ENTER THE HEIGHT AND BREADTH AREA OF TRIANGLE:6 1.CIRCLE 2.RECTANGLE 3.TRIANGLE 4.EXIT PROGRAM EXITED

#### Result:

Thus, the Implement the Concept of Function Overloading was executed successfully.
