Program plan: str,cmpstr variablesare used for inputs int strcmparr(const char s1[], const char s2[]) function stores string array reference in two array variables and compare the strings character by character using index variable and return the difference between character values. int strcmpptr(const char s1, const char s2) stores string array reference in pointer variables and copy compare the strings character by character using pointer arithmetic and return the difference between character values. Program description: The main purpose of the program is to demonstrate the working of built-in string function strcmp() by writing the two versions of each function. One version uses the pointer arithmetic to compare the strings. Second version uses array index to compare the strings.

(GREATEST COMMON DIVISOR) The greatest common divisor of integers x and y is the largest integer that evenly divides into both x and y. Write and test a recursive function gcd that returns the greatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equal to 0, then gcd (x, y) is x; otherwise, gcd (x, y) is gcd (y, x % y), where % is the remainder operator.

Question 4: (Find the minimum value in an array) Write a program that include a recursive function "recursiveMinimnm" that takes an integer array and the array size as arguments and returns the smallest element of the array. The function should stop processing and return when it receives an array of one element. Answer (2.5)

(Check test scores) The answers to a true-false test are as follows: T T F F T. Given a two-dimensional answer array, in which each row corresponds to the answers provided on one test, write a function that accepts the two-dimensional array and number of tests as parameters and returns a one-dimensional array containing the grades for each test. (Each question is worth 5 points so that the maximum possible grade is 25.) Test your function with the following data: int score = 0;
