8. Write a function called string_reverse() that accepts a string from the user as a parameter. The function should create and return a new string that contains all the same letters of the parameter string, but in reverse order. For Cedarbrae C.I. ICS3U example, string_reverse("Hello World") would return "dirolW olleW". Write a main () function to demonstrate how it works.

in python pls

Write a function in Scala programming language that takes a string parameter and returns whether the string starts with "Sc" or not. Test the function for the sample strings "Scala", "Programming", "Science".

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

Write a program that removes all spaces from the given input. Ex: If the input is: Hello my name is John. the output is: HellomynameisJohn. Your program must define and call the following function. The function should return a string representing the input string without spaces.string RemoveSpaces(string userString) #include <iostream>#include <algorithm>using namespace std; string removeSpaces(string str) { str.erase(remove(str.begin(), str.end(), ' '), str.end()); return str; } /* Define your function here */ int main() {string str; str = removeSpaces(str); cout << str << endl; /* Type your code here. Your code must call the function. */ return 0;} Please help me with this problem using c++.

Write a function named encode_string(sentence) that takes a string value as its input and returns an encoded string, where each character of the input string is replaced by its ASCII code plus 3 values. Whitespace characters should not be encoded. For example, if the function was passed the input string: Hello World then it should return: Khoor Zruog For example: Test sentence "Hello World" print (encode_string(sentence)) Result Khoor Zruog

Write a complete function called Main() that asks the user for an input string, then creates and prints a report of how many of each character occurred in that string. For example, here is a sample run: >>> Main() Enter a string --- computer science rocks!    2 ! 1 c 4 e 3 i 1  >>>   If you can put it in alphabetical order too that would be great!

Write a program that inputs a student's name in the following form: lastName, firstName middleName. The program will convert the name to the following form: firstName middleName lastName. Your program must read the student's entire name in one variable and must consist of a user-defined function that takes as input a string, consisting of a student's name, and returns the string consisting of the altered name. You can use the string function find to find the index of ,(the comma); the function  length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.

What is the correct code for this question?

A function that turns an argument to a string (call it “toString(…)”) is a great use of function overloading. In one sentence, why might this be? In one sentence, why should we generally verify the arguments are what we expect when writing a function?
