Hello, I am having trouble with this homework question for my c++ course.
Implement a Rational Number class with the following specifications.
Data members
a) numerator and denominator
Functions
a) Constructors:
1) default constructor
2) single parameter constructor to create numerator/1
3) dual parameter constructor to create numerator/denominator
4) Use constructor delegation across all constructors.
b) Accessors and Mutators for both data members.
c) Static recursive GCD function using Euclid's algorithm.
d) Static LCM function for two numbers.
e) Reduce function simplify a rational number. This function modifies its calling
object.
f) Your program should work with the supplied driver program.
Notes
LCM (Least Common Multiple)
This function returns the smallest multiple of a and b.
Step 1: Multiply a and b to find a common multiple.
Step 2: Divide the common multiple by the GCD of a and b.
Step 3: Return the result of Step 2.
Reduce:
This function reduces a fraction to…
in c++
A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.
Hi, I am having trouble with this homework question for my C++ course
1. Implement a Student class.
a. Create a class Student with the following private data members:1. name2. exam_1 grade3. exam_2 gradeb. Create all appropriate accessor and mutator functions.c. Assign appropriate access modifiers to insure encapsulation.d. Add a private calc GPA() function that calculates and returns the GPAbased upon the two exam grades.e. Add a public getGrade() function that:
1. Obtains the GPA from the private calc GPA() function.2. Returns a letter grade based upon the numerical GPA value.90 to 100 = A80 to 90 = B70 to 80 = C60 to 70 = D0 to 60 = F
f. Test all functions use following main.int main(){Student a;a.setName("David");a.setExam1(90);a.setExam2(80);cout<<a.getName()<<endl;cout<<a.getExam1()<<endl;cout<<a.getExam2()<<endl;cout<<a.getGrade()<<endl;}
