A for construct is a kind of loop that operates on items included in a list. Because of this, it continues to operate for as long as there are objects to be processed in the system. Is this statement correct or does it include an error?
When you print an instance of the class Food in Question 1, you get something like this: Building up your answer coder in Question 1, write a str 0 method for the class Food so that printing an instance of the class results in a string that is a combination of the value of the attributes taste and name, separated by a blank: DO NOT call the function. For example:
Automatic Indexes: Starting with the program from 16-2 which processes Death Valley data, modify the program such that it sets the temperature ranges based on the data contained in the file. Allow for the graph to display 10 degrees above the highest max and 10 degrees below the lowest minimum temperature. Use the station name to automatically generate an appropriate title for your graph as well.
addCourse: accepts an object of type Course as the first parameter and the idNum of the Student as the second parameter. The Course can be added only if the Student object with the specified idNum exists in the studentsList, Course does not exist in the coursesRegistered list for the Student, After adding the course, the number of credits, do not exceed 18. If the course is added successfully, return true, else return false.

A for construct is a loop that handles a list of items. So long as there are items to process, it continues to execute. Is this assertion true or false?

A for construct is a type of loop that works with the things in a list. Because of this, it will keep running as long as there are items in the system to be handled. Does this statement make a mistake or is it correct?
Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() { const int NUM_VALS = 4; int courseGrades[NUM_VALS]; int i; for (i = 0; i < NUM_VALS; ++i) { cin >> courseGrades[i]; } /* Your solution goes…
