Question
C+ Object Oriented Programming Assignment 1. Create a Fraction class and add your Name to the name fraction and use this as your class. For example, if your name is Mark John, then your class name should be FractionMarkl. 2. Create a class constructor for your Fraction class to handle the initialization appropriately. .There will be ONLY one constructor with 2 arguments. The constructor should have code to confirm the call/use of itself through the printing (e.g.," Calling Fraction (int, int)" ) and continue with the display of numerator and denominator after being initialized/built. 3. A member function print() that will print the current Fraction object. 4. A member function extractUncommonDigitt) that will return an array of common digits between the numerator and denominator. Reminderl In your program, no GLOBAL DATA are allowed, and you must write all needed functions (no library functions are allowed - Except for cin and cout and their functions / manipulators) · . Dynamic allocations must be released properly! . Test your output with data to be identified in class ( at least the same as being shown below as appropriate. Attach the output at the end of your application program (as comment). Followed with a comment block about your logic, code issues, and any other comments that you may have- YOU MUST PROVIDE-this comment block even with a "NO COMMENTS!" as content of this block. . .Explanation / Answer
