PROJECT ABSTRACTION
I am KIRTESH KHANDELWAL Student of 2nd year doing my Bachelor Degree in Computer
Application.
In the following pages I gave compiled my work learnt during my 2nd year at college. The subject
is C++ Programming Language. We are taking an example of Restaurant, There are menu lists
is displayed by the restaurant manager. Whenever the customer will go there restaurant
he/she can choose one or more receipe’s / items from the menu lists is restaurant.
The Following code represent is based on menu driven programming concept that are based
on concept of menus that are perform and executed at run time. This code represent as a
converter to convert the number into the respective following bases. Menu driven
programming concept that represent the list at run time and asked for the respective following
input from the menu list by the user at run time and after it will take
Input and process to convert into the respective number conversion bases and generate the
desired output to the user.
1. Decimal to Binary
2. Binary to Decimal
3. Decimal to Octal
4. Decimal to Hexadecimal
5. Octal to Decimal
6. Hexadecimal to Decimal
The above conversion represent the menu list that are based on Menu Driven C++
Programming Concept.
