Chapter 6, Problem 30SA

I know how set and function works ... but i just dont know how do i implement it on a C++ program.. here is the question that i have problem with a) User need add input for set A, B and Relation b) Add at least 2 operation of sets such as intersection, union, and etc. c) Add at least 2 operation of function such as transistive, symetric and etc. d) Write a program that able to pick any one of four options(TWO operation of set and TWO operation of relation)     example of the output

MUST BE DONE IN C - Allow the user to enter multiple pairs of x and y coordinates on a 2 dimensional graph (these numbers may be considered unitless) along with a text label for that set of points. You must use a "struct" data type to define how these are stored. - The x and y coordinates should be type "float" or "double" - Allow multiple data points to be entered by the user, so the first thing the user must ask is how many coordinates will be entered. Since multiple entries will be made you must create an array of that "struct" type. - Once all of the coordinates and labels are entered, calculate the distance between each set of points (you DO NOT have to store all of the distances!!!). In this lab you may use "math.h" (it may be useful). - Determine which coordinates are closest to each other out of all of the pairs. - Determine which coordinates are furthest from each other out of all of the pairs. NOTE!!!! There will be a 10 point value for efficiency. Please contemplate the BEST…

6. In Java, you have the opportunity to either use a predefined function/method or write a user-defined function/method. In this discussion, provide at least three criteria that would be used to develop an appropriate method of your choice and the rationale behind the selection of these criteria.

Implement in C Programming 6.10.2: Pass by pointer. Write a function call to ConvertMoney() to store the number of quarters, nickels, and pennies within the integer variables numQuarters, numNickels, and numPennies, respectively. Ex: If the input is 133, then the output is: Quarters: 5 Nickels: 1 Pennies: 3 #include <stdio.h> void ConvertMoney(int totalPennies, int* numQuarters, int* numNickels, int* numPennies) {   *numQuarters = totalPennies / 25;   totalPennies = totalPennies % 25;      *numNickels = totalPennies / 5;   totalPennies = totalPennies % 5;      *numPennies = totalPennies;} int main(void) {   int totalPennies;   int numQuarters;   int numNickels;   int numPennies;    scanf("%d", &totalPennies);      /* Your code goes here */      printf("Quarters: %d\n", numQuarters);   printf("Nickels: %d\n", numNickels);   printf("Pennies: %d\n", numPennies);      return 0;}

write a C++ program. Write a program that calculates and displays the average of a group of test scores, all integers, after the lowest score in the group has been dropped. There are six test scores in the group. The program must contain only the following functions in additionto the main:• void getScore should ask the user for a test score, store it in a referenceparameter variable, and validate it. This function should be called by the mainfunction once for of the six scores to be entered by the user.• double calcAverage should calculate and return the average of the five highest scores. This function should be called just once by the main function, and should be passed the six scores. Use pass by reference to receive the lowest test score.• int findLowest should find and return the lowest of the six scores passed to it. It must be called by the calcAverage function, which uses it to determine which of the six scores to drop.• void displayResults should be called by the main function…

in Haskell: rewrite the following function in two different ways: 1. as a sequence of transformations using the explicit application operator ($) 2.  as a composition of functions using the "dot" composition operator (.) stringToInt s = reverse [ord x - 48 | x <- s] stringToIntRec x (head : tail) = (x * head) + (stringToIntRec' (x*10) tail) stringToIntRec x [] = []

identify the following as better representing static or dynamic binding. a) an int is an int forever and ever amen b) 2/2.0 = 1.0 c) 3/2.0 -> error message d) binding is done at compile time e) binding is slower but more flexible

Problem 6: Induction and Recursion Consider a postal system for which the minimum postage required for any service (e.g. mailing a postcard) is 18 cents. [a] Prove by strong induction that any postage ≥ 18 can be formed using only 4-cent and 7-cent stamps. (Hint: consider bases cases for 18 thru 21.) [b] Write a Java/Python-like pseudocode for a function that determines the number of each denomination of stamp for a postage amount ≥ 18. (It need not be concerned with lesser cases as they are never used).
