The function overloading is the technique in which you can make the function with more than one name but only if you will change the paramaters or the number of the paramaters.


function overriding is one in which functions have the same name and same number,type of arguments.. its only the implementations that differs.. they are accessed based on the object of the class being called

function overloading is function name is same and parameter same but deffination of the function is deffrent .fuction perform the action is deffrent -deffrent <br>example-<br>class abc<br>{<br>int sum;<br><br>public int sum(int i, int j)<br>{<br>sum=i+j;<br>return(sum);<br>}<br>int mul;<br>public int sum(int i, int j)<br>{<br>mul=i*j;<br>return(mul);<br>}}<br>{<br>

Function over loading means two functions will have same name but they differ in the number or type of arguments. <br><br>Whereas function overriding means two functions will have same name , type and number of arguments. Typically these two functions will be in different classes (base and derived for example).

Function Overloading is defining more than one class with same function name but with diiferent number of arguments are with different datatypes of arguments<br><br><br>Example:<br>class sample<br>{<br>int s,m,d;<br>int sum(int a,int b)<br>{<br>s=a+b;<br>return(s);<br>}<br>int sum(int a,int b, int c)<br>{<br>m=a*b;<br>return(m);<br>}<br>float sum(float a,float b)<br>{<br>d=a/b;<br>returb(d);<br>}<br>}

Function overloading is the feature of C++ where two functions can have same but different arguments for example <br><br>Class CFunctionOverload {<br><br>Public:<br>void OverloadFunction(void);<br>void OverloadFunction(int param1);<br>void OverloadFunction(int param1, int param2);<br>void OverloadFunction(float param1);<br>}<br><br>

Function Overriding:-<br> The functions having the same name,parameters but having different definitions is called function overriding. It basically deals with the concept of Inheritance.when a Base class having some function and the derived class of it having same function, then this creates a problem called function overriding.

a function with same name can exist in 2 or more base class. now which function is used by derived class when it inherits the 2 classes is solved by overriding the function in derived class using (::) operator.
