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 function that when given a URL as a string, parses out just the domain name and returns it as a string. Examples:domain_name("http://github.com/SaadBenn") == "github" domain_name("http://www.zombie-bites.com") == "zombie-bites"domain_name("https://www.cnet.com") == "cnet"Note: The idea is not to use any built-in libraries such as re (regular expression) or urlparse except .split() built-in function""" # Non pythonic waydef domain_name_1(url): #grab only the non http(s) part full_domain_name = url.split('//')[-1] #grab the actual one depending on the len of the list actual_domain = full_domain_name.split('.') # case when www is in the url if (len(actual_domain) > 2): return actual_domain[1] # case when www is not in the url return actual_domain[0] # pythonic one linerdef domain_name_2(url):

Program 3 In an input string substitute all occurrences of a specific character by another pre-specified character. Both characters and the string are input by the user. The program should output: Original string: Substitute -→ Result string:

Given string userGreeting on one line and string userName on a second line, append a space to userGreeting. Then, append userName to userGreeting. Lastly, append a period to userGreeting. Ex: If the input is: Hey Wilma Lee then the output is: Hey Wilma Lee. #include <iostream>#include <string>using namespace std; int main() { string userGreeting; string userName; getline(cin, userGreeting); getline(cin, userName); /* Your code goes here */ cout << userGreeting << endl; return 0;}

In Python Create a program that reads a full name as a single string, and and uses the split creates a username with the following rules: The first character of the username is the first character of the first name. The second character of the username is the first letter of the middle name, if one was provided. The rest of the characters will be a prefix of the last name, long enough to meet the length requirement. The username can have up to 8 characters only, and in lowercase.

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

please created a c++ code regarding this screenshot i add and also please add professional comments in it using the // command

c++ problem. paste indented code Given the code:string s;cout << "Enter a string of any length: ";cin >> s; Write a loop to print every other character in the string s on its own line. Note that s can be a string of any length.Example Output 1Enter a string of any length: HelloHloExample Output 2Enter a string of any length: GoodbyeGobe

hideshow Write a function hideshow that accepts two string arguments, an input string and a masking string. The masking string is a string consisting of '0's and '1's that has the same length as the input string. The function then returns a new string that is the same as the input string, except that it is masked. That is, in any position where the masking string contains a '0' the input character is replaced by a '#', whereas if the masking string contains a '1', the character is unchanged. Sample usage:>>> hideshow('apple', '11001') 'ap##e'>>> hideshow('apple', '00000') '#####'>>> hideshow('apple', '11111') 'apple'>>> hideshow('abcdefghijklmnopqrstuvwxyz', 13*'01') '#b#d#f#h#j#1#n#p#r#t#v#x#z'>>> hideshow 'df###re##', '101010101' ) 'd#####e##'>>> hideshow( 'df###re%%', '101010101' )=='d#####e##' True

a. Write a program that reads your id and full name and display. And also display the index of first letter and last letter of your full name. b. Modify above program, Declare a string course, let your program read course from user, check if course is not equal to comp2002, clear the string otherwise concatenate course and " Computer Science Department". C. Modify above program declare a string college="". If string college is empty then assign a new string "College of Science".

Programing C

In C++ Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. n is different than N. Ex: If the input is: n Nobody the output is: 0 n's The program must define and call the following function that takes the input string and character as parameters, and returns the number of times the input character appears in the input string.int CalcNumCharacters(string userString, char userChar)
