Basic Concept of Function Overloading With Example

Concept of Function Overloading With Example

The very basic definition of function overloading in C++ is a function name having several definition that are differentiable by the number or the types of their arguments , is known as function overloading.

For Example 

The following example in which the code overloads a function area to find the values of area of circle ,rectangle and triangle.

float area(float r)

{

return 3.1*r*r;

}

float area (float len,float bre)

{

return len*bre;

}

float area(float side1, float side2, float side3)

{

float & = (side1+side2+side3)/2;

float ar = sqrt(&*(&_side1)*(&*(&_side2)*(&*(&_side3));

return ar;

}
