This question should be answered in C++ programming language. Please answer part 2 of this question as part 1 has already been answered through chegg. if GPA in the range of 2.5(inclusive) - 3:B if GPA in the range of 2(inclusive) - 2.5:C Less than 2: D > Print_Std_Info() : This function accepts the id of one student and prints out all the information of that student (all the attributes). Purpose: The purpose of this project is to allow you practice Object Oriented Design, Pointers, File /0, Exception Handling, Functions and Arrays. > Comapre_GPA(): This function compares the GPA of two students and returns the id of the student who has the higher GPA. Problem Objective: The objective of this problem is to create a fully functioning system that handles the records of students at Concordia University. Based on the following narrative, you need to come up with an Object-Oriented design to represent the different entities in the system. Part 2: Faculty Class: Assume the faculty of…
Implement the following functions in Scheme using the functions map and/or foldl. DO NOT use recursive definition for this problem. Define a function leq, which takes two lists of numbers (x1,x2,…,xn),(y1,y2,…,yn) and returns \#t if and only if x i≤y if or all 1≤i≤n. You can assume that the two lists have the same length.
Please write Lisp code for the following problem. Consider the list:((name (number1 nation)) (MusicPurchasedNorway) (Pressfreedom Norway) (NobelLiterWinners France)(MovieTixHighPrices Switzerland))write a function to access the MovieTixHighPricesvalue using carand cdr.2 (Your function should work on any property list with this set of properties in this order.)
Write a simple program in Scheme that displays three different behaviors, depending on whether we use let, let*,or letrec to declare a given set of names. (Hint: To make good use of letrec, you will probably want your names to be functions [lambda expressions].)

Write these codes in c language please. Thank you in advance. 1. Define a function CalcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. CalcPyramidVolume() calls the given CalcBaseArea() function in the calculation.Relevant geometry equations:Volume = base area x height x 1/3Base area = base length x base width.(Watch out for integer division). 2. Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 3, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7:42 seconds 3. Write a function PrintShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles…
Design DFA {w ∈ Σ ∗ | |w| ≥ 3 and the second symbol from the left end of w is different from the last symbol of w}. For example, 010100 is in the language, but 0001100 is not in the language.

Write the following function in Lisp: a function that takes one parameter that you can assume to be a symbol named after a day of the week (no need to check it), such as 'monday, and returns the symbol for the next day. For example, (next-day 'tuesday) should return the symbol 'wednesday. Implement this function with a complex conditional.

3.)Function composition We can define a higher order function, i.e. functional form, that accepts two functions as parameters and returns their sum, As an example, consider two functions below: f1(x) = x + 2 g1(x) = 3x + 4 These are modeled by the following Scheme functions, respectively: (define (f1 x) (+ x 2)) (define (g1 x) (+ (* 3 x ) 4)) The higher order function plus = f1 + g1: (define (plus func1 func2) (lambda (x) (+ (func1 x) (func2 x)))) Note the use of the lambda in order to return a nameless function. In essence, we are accepting two functions, func1 and func2, and returning a function that takes one parameter x and represents their sum. We can apply this functional form as follows: ((plus f1 g1) 10) ; returns 46. Or (define (plus func1 func2 x) (+ (func1 x) (func2 x)) ) (plus f1 g1 10) ; returns 46. Define a function (form) that compute the product of two functions and test your functions.
