(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 program’s 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…

(Quality Points for Student’s Grades) Write a function toQualityPoints that inputs a student’s average and returns 4 it’s 90–100, 3 if it’s 80–89, 2 if it’s 70–79, 1 if it’s 60–69, and 0 if theaverage is lower than 60

(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy                                        = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.
