Write a program called p3.py. Write a function called validate() that takes a string as input, validates that it is a single letter, and returns the letter in lowercase. Example: validate("A") returns a validate("abc") returns invalid

Write a C++ program that reads a sentence into a c-string of maximum 80 characters, a character into a variable called c, and an integer into n, and then passes all three of these variables to a function that searches for the character c and prints the character and the next n characters of the string, if the character is found. If it doesn't find the character in the string it must print "The character was not found." For example, if the user enters "Superbowl tickets are too expensive." and then enters t and 7, the function must print tickets.

Create a function that will test if a string is a valid PIN or not via a regular expression. A valid PIN has: Exactly 4 or 6 characters. Only numeric characters (0-9). • No whitespace. Examples validate("121317") → true validate("1234") → true validate("45135") → false validate("89abc1") → false validate("900876") → true validate(" 4983") false

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++.

Using Python write a string-comparison function named strNcompare that compares up to n characters of a string s1 with the other string s2. The function must return 0, -1, or 1 if the first n-character portion of s1 is equal to, less than, or greater than the corresponding first n-character portion of s2, respectively. (1) You must use the following function definition: def strNcompare(s1, s2, n): (2) String comparison must be case-insensitive. For example, the strNcompare function must return 0 for the s1 value of ‘tommy’ and the s2 value of ‘TOMMY’. (3) You should not use a loop such as the while loop and the for loop inside the strNcompare function. Then write a Python program that receives two words and the number of characters for comparison, calls the strNcompare function, and then shows the result. Your program keeps doing this until the user enters the value of -1. Your program displays the message ‘String comparison [1(play), -1(quit)]: ’ and receives the value 1 or -1...

Write a program to enter two strings from the user using function cin.getline and then appends string two with string one separated by a blank space. Sample Input: C++ is a good programming Language. Arrays are very integral part of this language. Sample Output: C++ is a good programming Language. Arrays are very integral part of this language.
