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;}
