Write a function is_palindrome(...) that returns a Boolean indicating whether a C-style string is a palindrome. Notice that is_palindrome(..) accepts two parameters: a_first that is a pointer to the first character, and a_last points to the '\0' character in the C- style string. Note: you may use pointer arithmetic if you wish here.

- pointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.In C language, write a program to input two integers x,y and add both the integers using pointers and display the result in the output. The assignment will be rejected if the numbers are added without the use of pointers.Instructions: In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString(). This preserveString() function has the following description: Return type - void Name - preserveString Parameters The string Length of the string Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function. Please Finish the code ASAP: This is my current given code: #include<stdio.h>#include<string.h> #define STR_MAX_SIZE 100 void preserveString(char*, int); int main(void) { char str[STR_MAX_SIZE]; printf("Enter string: "); fgets(str, STR_MAX_SIZE, stdin); preserveString(str,…
- Create a program in C language that calculates the month's day from a given year and year's day. Use pointers for the month and month's day variables. Don't forget to add proper errors handling in your program. Example or errors - Invalid Input- Invalid year- Invalid year day Example of input # ./month_day <year> <yearday> # Example for Feb 2nd, 2019:\$ ./month-day 2019 33Feb 02, 2019 I have this class - month-day.c - #include <stdio.h> /* month_day function's prototype*/void month_day(int year, int yearday, int *pmonth, int *pday); int main() {return 0;} Note: I don't need the calendar, please read the instructions well!!Please Help C++ Write a function that returns an integer and accepts a pointer to a C-string as an argument. The function should count the number of characters in the string and return that number. Demonstrate the function in a simple program that asks the user to input a string, passes it to the function, and then displays the function's return value.A Palindromic prime is a prime number that is also a palindromic number. Write a C++ program that displays all the palindromic prime numbers between 100 and 999 without using pointers.For example: These are 14 palindromic prime numbers smaller than 500:2,3,5,7,11,101,131,151,181,191,313,353,373,383.
- A palindrome is a string that reads the same in its reverse. For example maam, wow, racecar, madam etc. Write a function in C++ named palindrome. The function will take a character array as input and will return 1 if the string is a palindrome and 0 otherwise.IN C++ Write a program that computes the Greatest Common Factor for any given two values. The user should be able to enter as many values (sets of two) as needed. The program should do the following: 1. Allow the user to enter as many values as needed. 2. After the user enters all the values, the program displays each pair of values and the GCF. 3. The function to find GCF must be a recursive function. Here is the definition that you must use: GCF (n,m) = m if mIn c programming, Write a function findLetter based on the following rules: It takes a string named str and a character named ch as parameter, returns the index of the first occurrence of the character ch if the str string contains the character ch; If the relevant character is not found in the string, write a function that returns -1. Call the function inside the main function and test it. You should use the prototype given below: int findLetter (char str [], char ch)
- Complete the check_strings_same_start(word1, word2) function which is passed two string parameters. The function returns True if the two parameter strings start with the same character and only one (not both) of the parameter strings has an even number of characters (including any space characters), otherwise the function returns False. For example: Test Result result = check_strings_same_start("blue", "bag") True print(result) print(check_strings_same_start("babyproofing", "baby")) False print(check_strings_same_start("check", "fact")) FalseIn C language, Write a function that gets a string containing a positive integer. The function subtracts 1 fromthat integer and puts the obtained value in the string. void str_subtract_one(char* num); For example:- if before we call str_subtract_one(str) we have str==“1997”, then after return str will be “1996”.- if before we call str_subtract_one(str) we have str==“12345678987650”, then after return str will be “12345678987649”.- if before we call str_subtract_one(str) we have str==“100”, then after return str will be “99”. 1. You may assume that the input is always legal, i.e., the string is a positive integer correctly formatted.2. Note that the numbers may be larger than the maximum of int or long. That is, you should not try to convert string to intIn C++, Write a function named that accepts argc and args with the same data type as command line arguments (int argc, char * args[]). It will return two boolean values. It checks whether each of command line argument ending with a comma (‘,’) or not. If they all are, it will return true. Otherwise, it returns false. It will also return true if there is no argument is given. In addition, it also returns another boolean flag indicating whether one of the arguments is just a comma only.For this question, you are not allowed to use string class and its method or string function such as strlen.
