If the variable named Box had the user-defined type RectangleType defined by struct RectangleType { float length; float width; float height } What expression would be used to reference the length of Box?

Here is my code:  #include<stdio.h>struct timeType_struct {int hr;int min;int sec;};typedef struct timeType_struct timeType;struct tourType {char city[50];int distance;timeType time;};typedef struct tourType tourType;void printTour(tourType *);tourType getData();tourType tours[3];int main() {int i=0, min;printf("Enter tour data for 3 cities...\n");for (i = 0;i < 3;i++) {tours[i] = getData();}min = tours[0].city;for (i = 0;i < 3;i++) {if (tours[i].distance < min)min = tours[i].distance;}printf("\n");for (i = 0;i < 3; i++) {if (tours[i].distance == min) {printTour(&tours[i]);}}getchar();return 0;}void printTour(tourType* x) {printf("Shortest Tour\n---------------\n");printf("City name: %s\n", (*x).city);printf("Distance: %d\n", (*x).distance);printf("Travel time: %02d:%02d:%02d", (*x).time.hr, (*x).time.min, (*x).time.sec);}tourType getData() {tourType x;char a[5], b[5], c[5]; //Will be used for time inputprintf("Enter a city name: ");scanf("%s",…

When defining an array of a classtype, a C++ programmer has no way to specify which overloaded constructor is used on each declared array element, as the default no-argument constructor will always be used no matter what. True O False

C++ Write a function named “createPurchaseOrder” that accepts the quantity (integer), the cost per item (double), and the description (string). It will return a newly 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.

For what reason should you use new instead of the old operator when creating instances of a structure?

C++ coding project just need some help getting the code thank you!

In c++ Create a structure named student with two attributes, name and copa. Define structure variables s1, in the main block(local to main menthod), s2(global), two structure variable as an array. Scan over all four structure variables and display. For example: Test Input Result 1 218CES001 7.1 215001 7.1 218CE500) 7.3 2105004 21BCES003 7.3 218CES004 7.4 7.4 218CE5002 21BC5002 7.2 7.2

Define a struct type that represents an exercise plan. The struct should store the following data: plan name (a character array of size 50) and goal calories to burn (an integer). The type should be renamed from struct exercise_plan to Exercise_plan.

this is ony one quiestion so please answer them all. USE C++

When you successfully construct an instance of a structure, what do you get exactly?
