Riya took part in a maths quiz competition. To win the prize money she has to solve a tricky question at the end.For a given list of integers, write a program where all the integers in a given index range to be added.
She will be given M multiple ranges, where she should print the sum of numbers for each corresponding range.

Note: The limits in the range are both inclusive.

Input
The first line f input is space-separated integers.
The second line of input is a positive integer M denoting the number of index ranges.
The next M lines contain two space-separated integers of the range.

Output
The output should be M lines.
Each line contains an integer that represents the sum for the corresponding ranges.

Sample Input1
1 3 4 5 6
5
3 5
Sample Output1
12

Class Distance with private attributes Feet (int) and Inches (float). Also, define public member functions:

 Set_distance( )

 Display_distance( ) – to display the values of class attributes

Include a main ( ) program that creates an instance (object) of type Distance. Ask the user to enter the value of Distance variables and call the appropriate functions to set the object value and then display the object value.

Define the class member functions outside the class using scope resolution operator (::).

Task 7-01

 Define a constructor for the class Distance, that should initialize the Distance attributes (feet, inches) to 0.

 define an overloaded constructor that initializes the object to certain values.

e.g, Distance d1, d2(10,2) initialize d1 to 0 and values of d2 to 10, 2

Task 7-02

 Make changes to the Set_distance( ) function and class constructor so that the values of inches never exceed 11. e.g

obj.Set_distance (10,12) - the value of obj members will be feet: 11, inches: 0

Consider a toll plaza on a bridge. Cars passing through the toll plaza must pay a toll of Rs.30/-. Most of the time, they do, but every now and then, a car drives by without paying. The toll plaza records the number of cars that have passed through as well as the total amount of money collected. Model this toll-plaza with the help of the toll-plaza class. The classs two data items are to hold the total number of cars and to hold the total amount of money collected. For the c++ class, implement:

 A constructor that initializes both data items to 0.

 A member function called payingCar() increments the car total and adds 30 to the cash total.

 Another function, called nopayCar() that increments the car total but adds nothing to the

cash total.

 Finally, a member function called display() should display the total cars and the total cash collected.
