# C++ Relational Operator Overloading
[ C++ Overloading Operators and Functions](#)
The C++ language supports various relational operators (, =, ==, etc.), which can be used to compare built-in data types in C++.
You can overload any relational operator. Once overloaded, the relational operator can be used to compare objects of a class.
The following example demonstrates how to overload the < operator. Similarly, you can try overloading other relational operators.
## Example
#include
using namespace std;
class Distance
{
private:
int feet;// 0 to infinity
int inches;// 0 to 12
public:
// Required constructors
Distance(){
feet =0;
inches =0;
}
Distance(int f, int i){
feet = f;
inches = i;
}
// Method to display distance
void displayDistance()
{
cout<<"F: "<< feet <<" I:"<< inches <<endl;
}
// Overload negative operator ( - )
Distance operator-()
{
feet =-feet;
inches =-inches;
return Distance(feet, inches);
}
// Overload less than operator ( < )
bool operator <(const Distance& d)
{
if(feet < d.feet)
{
return true;
}
if(feet == d.feet&& inches < d.inches)
{
return true;
}
return false;
}
};
int main()
{
Distance D1(11, 10), D2(5, 11);
if( D1 < D2 )
{
cout<<"D1 is less than
