What is the difference between the use of an index-based loop and the use of an iterator with an array? Give an example to support your answer.

Implement in C Programming 6.11.2: Modify an array parameter. Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. #include <stdio.h> /* Your solution goes here  */ int main(void) {   const int SORT_ARR_SIZE = 4;   int sortArray[SORT_ARR_SIZE];   int i;   int userNum;    for (i = 0; i < SORT_ARR_SIZE; ++i) {      scanf("%d", &sortArray[i]);   }    SwapArrayEnds(sortArray, SORT_ARR_SIZE);    for (i = 0; i < SORT_ARR_SIZE; ++i) {      printf("%d ", sortArray[i]);   }   printf("\n");    return 0;}

---for example, Data abstraction is a powerful concept in computer science that allows programmers to treat code as objects car objects, chair objects, people objects, etc. That way, programmers don't have to worry about how code is implemented they just have to know what it does. Data abstraction mimics how we think about the world. For example, when you want to drive a car, you don't need to know how the engine was built or what kind of material the tires are made of. You just have to know how to turn the wheel and press the gas pedal. An abstract data type consists of two types of functions: • Constructors: functions that build the abstract data type. • Selectors: functions that retrieve information from the data type. For example, say we have an abstract data type called city. This city object will hold the city's name, and its latitude and longitude. To create a city object, you'd use a constructor like city=make_city (name, lat, lon) To extract the information of a city object,…

Implement the following functions. Each function deals with null terminated C-Style strings. You can assume that any char array passed into the functions will contain null terminated data. Place all of the functions in a single file and then (in the same file) create a main() function that tests the functions thoroughly. You will lose points if you don't show enough examples to convince me that your function works in all cases. Please note the following: You may not use any variables of type string. This means that you should not #include <string>. Also, you may not use any c-string functions other than strlen(). If you use any other c-string functions, you will not get credit. Note, however, that functions such as toupper(), tolower(), isalpha(), isspace(), and swap() are NOT c-string functions, so you can use them. Also note that this prohibition is only for the functions that you are assigned to write. You can use whatever you want in your main() function that tests the…
