Complete the given CPP function definition and run it for a test case. void swapString(string &str, int i, int j){ //check whether i and j are in the range //0 to str.length()-1 and i is less than j. //if the conditions are true then swap the //characters at index i and j in the string.

Define a function FilterStr() that takes a string parameter and returns "Acceptable" if the first character and the character at index 3 in the string parameter are the same. Otherwise, the function returns "Unacceptable". Ex: FilterStr("surfing") returns Unacceptable Recall string's at() returns a character at the specified position in the string. Ex: myString.at(3) #include <iostream>#include <string>#include <cctype>using namespace std; /* Your code goes here */ int main() {   string input;   string output;    getline(cin, input);        output = FilterStr(input);   cout << output << endl;    return 0;}

code should be python: write a function that allows the input of a list of strings as its only parameter. Inside the body of the function find the first palindromic word and return it. If there is no such word, it should return an empty string. A string is palindromic if it reads the same forward and backward so for example If we call the function with [“horse”, “rat”, “roar”, “dad”, “mom”], the returned value should be “dad”. Note that “mom” is also a palindrome, but it is not the first one.

Write a function called reverse that takes a parameter N which is a string and returns the reverse of the string.

python help... Write a function justVowels() that takes a string as a parameter and returns a new string that contains all the vowels found in the parameter string. The vowels in the returned string should appear in the same order as they did in the parameter string. A vowel is one of a, e, i, o, or u. both the upper- and lower-case vowels should be included. The characters in the returned string should have the same capitalization as they did in the parameter string. If the function is given a string without any vowels or an empty string, it should return the empty string. Use the if-else condition with iterate loop pattern. Don’t forget to include the docstring and comments.    How it should run... >>> justVowels('Did you include your collaboration statement') 'iouiueouoaoaioaee' >>> justVowels('If you did not include your collaboration statement no points') 'Iouioiueouoaoaioaeeooi' >>> justVowels('1,2,3,4,...') '' >>> justVowels('') ''

-Python- Write a function get_letter_grade, such that when given * a lab grade score and * a list of the grade cutoffsreturns the letter grade of that score.Note: Your function automatically returns A for the values that are >= to the first cutoff-value in the list, then A- for the second cutoff-value, B+ for the third and so on. The function returns None for anything that's below the score for B-. You test that get_letter_grade(97, [93, 90, 87, 83, 80]) correctly returns an A, and get_letter_grade(93, [97, 90, 87, 83, 80]) returns A-. DO NOT hard-code the cutoffs, since they can change! You can copy/paste the following template: def get_letter_grade(score, cutoffs):    if score ... :        return 'A'    ...:        return 'A-'    ...:        return 'B+'    ...:        return 'B'    ...:        return 'B-'

You must use an STL container (such as list or vector) for this assignment; solutions not using an STL container are not acceptable. Write a C++ program to get up to ten integers from the user, store them in an STL container, and then calculate and display: (1) the mean (2) the variance of the population (see https://www.statisticshowto.com/population-variance/ for the formula and an example) (3) the standard deviation (the square root of the variance)

Implement the following C function: repeatChars take in a null-terminated string as an argument and returns a newly- allocated null-terminated string that repeats every character in the input string. For example, repeatChars(''abcd'' )=''aabbccdd'' . You may use the strlen function to determine the length of the string your implementation does not need to check whether malloc returns NULL C Your implementation should not modify the input string

Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substr() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3/1/1990 12/13/2003   main.cpp #include <iostream>#include <string> using namespace std; int DateParser(string month) {int monthInt = 0;if (month == "January")monthInt = 1;else if (month == "February")monthInt = 2;else if (month == "March")monthInt = 3;else if (month == "April")monthInt = 4;else if (month == "May")monthInt = 5;else if (month == "June")monthInt = 6;else if (month == "July")monthInt = 7;else if (month == "August")monthInt = 8;else if (month == "September")monthInt = 9;else if (month == "October")monthInt = 10;else if (month ==…

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?
