Concept explainers

C-string

A string is a one-dimensional array of characters that can be terminated using a null character (‘\0’). The string or character array is used to manipulate the text such as words or sentences. The \0 (termination character) is the most important in the string as it is the only method to identify the end of the string. A string can be defined as a one-dimensional array of characters; whereas, an array of strings is a two-dimensional array of characters.

QUADRATIC PRIMES This question is adopted from Project Euler Question 27. (https://projecteuler.net/problem=27) The quadratic formula n^2 + n + 41 will produce 40 primes for consecutive integer values 0 <= n <= 39. However, when n = 40, this formula will not generate a prime number. Another interesting quadratic formula n^2 – 79n + 1601 produces 80 prime numbers for consecutive values 0 <= n <= 79. The Question: find a and b such that when -999 <= a <= 999 and -1000 <= b <= 1000, the quadratic form ?^2 + ? × ? + ? produces the maximum number of primes for consecutive values of n, starting with n = 0. Requirement: MUST BE WRITTEN IN C++ - Print the 40 primes generated by formula n 2 + n + 41 - Print the 80 primes generated by formula n 2 – 79n + 1601 - Write a function that takes in an integer and returns whether the given number is prime or not. - Output the value of a, b and how many consecutive values of n (count the starting zero!) can be generated. - Submit…

Please solve as a C programming
Provide answer in C language please You are tasked with creating a program that takes in an array of integers and sorts them in ascending order using a custom sorting algorithm. The custom sorting algorithm should be based on the following rules: The sorting algorithm must use a divide-and-conquer approach. The sorting algorithm must be recursive. The sorting algorithm must have an average case time complexity of O(n log n). The sorting algorithm must have a worst case time complexity of O(n^2). The sorting algorithm must be stable, meaning that the relative order of equal elements should be preserved.
