It provides multiple definitions of the function by changing signature i.e changing
number of parameters, change datatype of parameters, return type doesn’t play
anyrole.

ഭ |tcan be done in base as well as derived class.
= Example:
‏ا‎

void area(int a);

void area(int a, int b);

// CPP program to illustrate
// Function Overloading
#include
using namespace std;

// overloaded functions
void test (int) 7 void
test (float);
voidtest(int, float);

int main ()
{ inta = 5;
floatb = 5.5;
// Overloaded functions
// with different type and
// number of parameters
test(a); test (5) 7
test(a, b);

return 0;

// Method 1
void test (int var)
{

cout << "Integer number: "<< var << endl;

// Method 2 void
test (float var)
{

cout << "Float number: "<< var << endl;

// Method 3

voidtest(int 7321, float var2)

{
cout << "Integer number: "<< varl;
cout << " and float number:" << var2;
