Hi I'm trying to finish my last 3 assignments and I can't seem to figure out the code, it's bugging me if you could look at my code, say what's wrong, input the write code it be greatly appreciated, I will rate highly thank you in advance this is for C++ programming language.

(Fraction calculator) | Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which _a_ and _b_ are integers and b 0. Your program must be menu driven, allowing the user to select the operation (+, , *, or /) and input the numerator and denominator of each fraction. Furthermore, your program must consist of at least the following functions:

Function menu: This function informs the user about the programs purpose, explains how to enter data, and allows the user to select the operation.

Function addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.)

Function subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.)

Function multiplyFractions: This function takes as input four integers representing the numerators and denominators of two fractions, multiplies the fractions, and returns the numerators and denominators of the result. (Notice that this function has a total of six parameters.)

Function divideFractions: This function takes as input four integers representing the numerators and denominators of two fractions, divides the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.) Some sample outputs are:

3 / 4 + 2 / 5 = 23 / 20

2 / 3 * 3 / 5 = 6 / 15

Your answer need not be in the lowest terms.
