In c++ The Fibonacci numbers are a series of numbers that exhibit the following pattern:   0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …   The series starts with 0 and 1, and each subsequent number in the series is the sum of the previous two numbers. The Fibonacci sequence, Fn, is defined by the following recurrence relation:   Fn = Fn-1 + Fn-2   Where the initial values are F0 = 0 and F1 = 1. Write a program that prompts the user to enter in a positive integer N and generates the Nth Fibonacci number. Your main function should handle user input and pass that data to a function called Fib that takes integer N as input and returns the Nth Fibonacci number. Include the functions preconditions and postconditions as comments in your source code. Include some basic input validation to make sure the function’s preconditions are met before the function is called. Show your source code and a sample of your program output.

please solve number C I solved numbers a and b so I do not need number a and b  Problem (taken from page 308 of the textbook)A parking lot has 31 visitor spaces, numbered from 0 to 30. Visitors are assigned parking spaces usingthe hashing function h(k) = k mod 31, where k is the number formed from the first three digits on avisitor’s license plate.a) Which spaces are assigned by the hashing function to cars that have these first three digits ontheir license plates: 317, 918, 007, 100, 111, 310?b) Describe a procedure visitors should follow to find a free parking space when the space they areassigned is occupied.c) A large parking-systems company would like to automate your assignment procedure forselfparking cars. You have been hired to implement a ”simple” proof-of-concept program in C++, fornow customers will enter their 3 digit plate numbers and your software will assign a parkingspace. Your implementation should a find a free parking space if the original assigned space isoccupied.…

LINKED LIST IMPLEMENTATION Subject: Data Structure and Algorithm in C++Create a Student Record Management system that can perform the following operations:1) Insert student records2) Delete student record3) Show student record4) Search student record The student record should contain the following items1) Name of Student2) Student Matriculation ID number3) Course in which the student is enrolled4) Total marks of the student Approach: With the basic knowledge of operations of Linked Lists like insertion, deletion of elements in linked list, the student record management can be created. Below are the functionalities explained that are to be implemented.●Check Record: It is a utility function of creating a record it checks before insertion that the Record Already exist or not. It uses the concept of checking for a Node with given Data in a linked list.-Create Record: It is as simple as creating a new node in the Empty Linked list or inserting a new node in a non-Empty linked list.-Search…

Write in C Language Description Please finish the following function char *replace(charsource, char constpattern, char constreplacement) A sequence of calls to this function replace the pattern with replacement. On a first call, the function expects a C string as argument for source, and this function scan for source to find the first pattern appear in source than replace it with replacement. In subsequent calls, the function expects a null pointer and uses the position right after the end of the last replacement as the new starting location for scanning. This function return source. Please see following example. char source[100] = "1223456789", pattern[10] = "2", replacement[10] = "123"; printf("%s", replace(source, pattern, replacement)); //Here should print out 112323456789 printf("%s", replace(source, pattern, replacement)); //Here should print out 11123323456789 printf("%s", replace(NULL, pattern, replacement)); //Here should print out 1112331233456789   function char…
