Program ID

Design an OOP model and implement it using C++ program. Refer the declaration of classes and application program to do the design. The program must get the details, compute bill amount and print details both for ordinary and preferred customers. For example, if a preferred customer makes three purchases of amounts 3000, 7000, 8000 then the amount to be paid for each bill is 3000, 6860 and 7760 and the total amount to be paid is 17620

Vector of Characters (Id-1498)

Bonus Practice Sheet Winter 2018 [17-Mar-2018 to 7-Apr-2018]

Program ID- 1498

Design a class charVector that has a character vector as data member. Provide member functions in the class to createVector, duplicateVector, duplicateRevVector and print. Functions shall be defined as follows: initializeVector – read a string and create a vector of characters duplicateVector – Add the content of the vector once at the end. For example if the content of charVector is “bat” then after the function is called the content must “batbat” duplicateRevVector – Add the content of the vector in reverse at the end. For example if the content of charVector is “bat” then after the function is called the content must “battab” print – Print content of vector, use iterators for traversal Use the vector class defined in STL for the implementation. Use [] operator in functions duplicateVector, duplicateRevVector and use iterator in print and initializeVector functions.
