In 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 int
Write a function that reverses a string. The header of the function is: def reverse(s):Write a test program that prompts the user to enter a string, invokes the reverse function, and displays the reversed string.
Scala Programming: Given string str, write a Scala program to create a new string where "Scala " is added to the front of a given string. If the string already begins with "Scala", return the string unchanged. Otherwise, return the string after adding "Scala ". Test the function for two strings "Scala Programming" and "Programming" inside the main method.
Write a function that returns a binary string from an octal number. The function header is as follows: string octal2Binary(const int& octalNumber) Write a test program that prompts the user to enter an octal number, uses octal- 2Binary function to parse it into an equivalent binary string and displays the binary string.
4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is “aBdDEfgHijK” then show_upper should return “BDEHK”. It should return the upper-case string - not print it. Do not change anything outside show_upper.
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")) False
python only** define the following function: This function accepts a string as its only parameter, and it must return a tuple containing first the length of the string, and then the string itself. Define lengthAndValue with 1 parameter Use def to define lengthAndValue with 1 parameter Use a return statement Within the definition of lengthAndValue with 1 parameter, use return _in at least one place. Do not use any kind of loop Within the definition of lengthAndValue with 1 parameter, do not use any kind of loop.

In C++, Write a function that receives a string of characters and return true if the string is in language, otherwise it returns false. You may use following function header (Assume a string is in language if it is read from the left side is the same as it is read from the right side. For example, a-b-d-c is not in the language, a-b-c-a-c-b-a is in language): bool isInLanguage_2(string aString) And I also, want to know if my if statement is incorrect, and if it is how is it incorrect?
PYTHON Problem Statement Implement a function which takes two arguments: the first is a string and the second is a single character (as a string). This function should move every instance of the given character in the string to the end of the string, and then return (do NOT print) the final string. NOTE: Only write code within the function. You do not need to utilize the "input()" function. The autograder passes inputs directly to the function as arguments, and the checked output is the returned value from the function. Sample Input "hello how are you?", "o" Sample Output "hell hw are yu?ooo" Starter Code def move_character(word, character):
Topics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()…
vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage: >>> vowelIndex('hello') 1 >>> vowelIndex('string') 3 >>> vowelIndex('string') 3 >>> vowelIndex('BUY') 1 >>> vowelIndex('APPLE') 0 >>> vowelIndex('nymphly') -1 >>> vowelIndex('string')==3 True >>> vowel Index ('nymphly')==-1 True
