Program Plan Intro
String Reverser
Program Plan:
- Include the required header files.
- Declare the necessary function prototype and constants.
- Define the main () function.
- Declare the necessary variables.
- Get the required input from the user.
- Call the method “reversestring()” to reverse the string.
- Display the string after reversing.
- Define the “reversestring ()” method,
- Condition that validates the length of the string, if the length of the string is less than “0” it gets returned as an empty string.
- If the length of the string is greater than “0”, then given string gets reversed and will be displayed.

Recursive PrintingDesign a recursive function that accepts an integer argument,n , and prints the numbers 1 up through n .
Recursive Power FunctionWrite a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the function in a program.

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,…

Q Search kola shreya@columbus X275: Recursion Programming Exercise: Check Palindrome X275: Recursion Programming Exercise: Check Palindrome Write a recursive function named checkPalindrome that takes a string as input, and returns true if the string is a palindrome and false if it is not a palindrome. A string is a palindrome if it reads the same forwards or backwards. Recall that str.charAt(a) will return the character at position a in str. str.substring(a) will return the substring of str from position a to the end of str,while str.substring(a, b) will return the substring of str starting at position a and continuing to (but not including) the character at position b.

If str1 = If str1 = If str1 = If str1 = “washer” and str2 = “dishwasher” then your function should return “wash” and str2 = “dishwasher” then your function should return “” and str2 = “test” then your function should return True. “test” and str2 = “” then your function should return False.“” and str2 = “” then your function should return True.“test” and str2 = “test” then your function should return True.arrow_forward
- Computer science C prog Create a recursive function that finds if a number is palindrome or not(return true or false), A palindromic number is a number (such as 16461) that remains the same when its digits are reversed.

The function should return 0 if the parameter string contains only digits. Note: you may not use loops of any kind. You must use recursion to solve this problem. You can assume that the parameter string is not empty. For example: Test Result print(count_non_digits ('123')) print(count_non_digits ('2rPTy5')) print(count_non_digits ('hello world')) 11 Precheck Check 0 4 Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) 1arrow_forward

Examples: abcd becomes cdab. abcde becomes deCab AhmadAlami becomes AlamiAhmad Page 1 of 2 Your program must: • Implement function void reflect (char* str) which receives a string (array of characters) and mirrors it. This function does not print anything. • Read from the user (in main()) a string and then print the string after calling function reflect(). • Use pointers and pointer arithmetic only. The use of array notation and/or functions from the string.h library is not allowed.arrow_forwardPython Language Useful websites: : http://en.wikipedia.org/wiki/Radix http://www.purplemath.com/modules/numbbase.htm Special Rules: Use only Boolean/math expressions and conditional statements (if-statements).
