5. complex numbers, fractions are useful things in of C++. Here, engineering and mathematics but are not a part you are going to do something about that. A fraction consists of two ints: the one on top (often called the numerator), and the one on the bottom (the denominator). The numerator can be any value, but it is normal to insist that the denominator is strictly greater than zero. a. Define a C+ struct (object) that could be used in a program to represent a fraction, together with a set function that can be used to set up the value of a fraction, and a print function that will print a fraction nicely. For example, using your definitions, this piece of program: ( fraction a, b,c set (a, 2, 3) set (b, 1, 5) set (c, 3, 5) print (a); print (b):.. should produce this output: b. I'm sure you remember how to work arithmetic on fractions, and you certainly recall that (a/b) + (c/d) comes out to be Write two C++ functions that work on fractions. One should add two fractions together, the other should multiply two fractions together. The exact details of their design are up to you, but neither should perform any input or output. Example: c-add (a, b)i add (a, b) print (a)i either or print( c)a should produce this output: (13/15) continued
