- Create a function named fnTuition that calculates the tuition for a student. This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0) tuition = 0 else if (student units >= 9) tuition = (full time cost) + (student units) * (per unit cost) else tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.arrow_forwardc++ code Screenshot and code is mustarrow_forwardANSWER LETTER B USE FLOWCHART IN DESIGNING THE LOGICarrow_forward
- C++ Write a function named “createPurchaseOrder” that accepts the quantity(integer), the cost per item (double), and the description (string). It will return anewly created PurchaseOrder object holding that information if they are valid:quantity and cost per item cannot be negative and the description cannot be empty or blank(s). When it is invalid, it will return NULL to indicate that it cannot create such PurchaseOrder object. PurchaseOrder createPurchaseOrder(int quantity, double costPerItem, string description) { if(quantity < 0 || costPerItem < 0.0 || description == "") return NULL; else { PurchaseOrder p = new PurchaseOrder(quantity,costPerItem,description); return p; } } what's the issue with this function and how to rewrite itarrow_forwardIn C++arrow_forward#include<stdio.h>#include<stdlib.h> int cent50=0;int cent20=0;int cent10=0;int cent05=0; void calculatechange(int* change){if(*change>0){if(*change>=50){*change-=50;cent50++;}else if(*change>=20){*change-=20;cent20++;}else if(*change>=10){*change-=10;cent10++;}else if(*change>=05){*change-=05;cent05++;}calculatechange(change);}}void printchange(){if(cent50)printf("\n50cents:%d coins",cent50);if(cent20)printf("\n20cents:%d coins",cent20);if(cent10)printf("\n10cents:%d coins",cent10);if(cent05)printf("\n05cents:%d coins",cent05);cent50=0;cent20=0;cent10=0;cent05=0;}void takechange(int* change){scanf("%d",change);getchar();}int main(){int change=0;int firstinput=0;while(1){if(!firstinput){printf("\nEnter the amount:");firstinput++;}else{printf("\n\nEnter the amount to continue or Enter -1 to…arrow_forward
