// Step 1: create the class loc.
// Step 2: Declare the constructor loc .which initialize the member variables.
// Step 3: Declare the member operator functions with the keyword operator.
// Step 4: Define the user specified operators behavior in operator function definitions.
// Step 5: Create the objects for the class loc.
// Step 6: Use the user defined operators for objects.
// Step 7: Monitoring the output values.
