Answer / jerry
function overloading - function name will be same but
operation will be different for eg:
if we take the function as area
then 1. area(int x,int y)
2. area(int x);
these r the two functions with the same name but
they will differ by their arguments given
for the 1st function
it becomes the area of the rectangle=x*y
for the 2nd function it becomes the area of square=x*x
coming to the operator overloading,
it is an overloading function of an operator.
if we + as an operator
a+b then + is operator for the operands a,b
c+d then + is also an poperator for the c,b.
these r the two properties of polymorphism.

Answer / manjeetsheoran
we can use the same function name but function signature are
differnt is called function overloading
for example
niit(int a int b)
niit(int a string name)

Answer / sagar sapkota
A function is overloaded when same name is given to different function. However, the two functions with the same name will differ at least in one of the following.
a) The number of parameters
b) The data type of parameters
c) The order of appearance
These three together are referred to as the function signature.
For example if we have two functions :
void foo(int i,char a);
void boo(int j,char b);
Their signature is the same (int ,char) but a function
void moo(int i,int j) ; has a signature (int, int) which is different
While overloading a function, the return type of the functions need to be the same.
In general functions are overloaded when :
1. Functions differ in function signature.
2. Return type of the functions is the same.
Operator overloading allows existing C++ operators to be redefined so that they work on objects of user-defined classes. Overloaded operators are syntactic sugar for equivalent function calls. They form a pleasant facade that doesn't add anything fundamental to the language (but they can improve understandability and reduce maintenance costs).

Answer / jha
Both function overloading and operator overloading is same
thing we can reuse the thing. In operator overloading we
can reuse the operator and user can work through object;
In function overloading we can overloading the same method
in derived class.

What is function overloading?,describe it with the example.
#include <string.h> #include <stdio.h> #include <stdlib.h> #include <conio.h> void select(char *items, int count); int main(void) { char s[255]; printf("Enter a string:"); gets(s); select(s, strlen(s)); printf("The sorted string is: %s.\n", s); getch(); return 0; } void select(char *items, int count) { register int a, b, c; int exchange; char t; for(a = 0; a < count-1; ++a) { exchange = 0; c = a; t = items[ a ]; for(b = a + 1; b < count; ++b) { if(items[ b ] < t) { c = b; t = items[ b ]; exchange = 1; } } if(exchange) { items[ c ] = items[ a ]; items[ a ] = t; } } } design an algorithm for Selection Sort
