C++ part 4: I have these error i am missing the ExecuteMenu Function 

This is my code so far. 

#include <iostream>
#include <string>

using namespace std;

int GetNumOfNonWSCharacters(const string text);
int GetNumOfWords(const string text);
int FindText(string text, string sample_text);
string ReplaceExclamation(string text);
string ShortenSpace(string text);

char PrintMenu(string sample_text){
char option;
cout << "\nMENU"<<endl;
cout << "c - Number of non-whitespace characters"<<endl;
cout << "w - Number of words"<<endl;
cout << "f - Find text"<<endl;
cout << "r - Replace all !'s"<<endl;
cout << "s - Shorten spaces"<<endl;
cout << "q - Quit"<<endl;
cout<<endl;
cout << "Choose an option:"<<endl;
cin >> option;

if(option == 'c'){
int nonWSCharacters = GetNumOfNonWSCharacters(sample_text);
cout << "Number of non-whitespace characters: "<<nonWSCharacters<<endl;
}else if(option == 'w'){
int numOfWords = GetNumOfWords(sample_text);
cout << "Number of words: "<<numOfWords<<endl;
}else if(option == 'f'){
cout<<"Enter a word or phrase to be found:"<<endl;
string phrase;
cin.ignore();

}else if(option == 's'){
string edited_text = ShortenSpace(sample_text);

}
}

}

5.20 LAB*: Program: Authoring assistant
(1) Prompt the user to enter a string of their choosing. Store the text in a string. Output the string.
Ex:
Enter a sample text:
We'll continue our quest in space.
There will be more shuttle flights and more shuttle crews and,
yes,
more volunteers, more civilians,
more teachers in space. Nothing ends here;
our hopes and
our journeys continue !
You entered: We'll continue our quest in space.
There will be more shuttle flights and more
shuttle crews and,
yes,
more volunteers, more civilians,
more teachers in space. Nothing ends
here;
our hopes and our journeys continue!
(2) Implement the PrintMenu() function to print the following command menu.
Ex:
MENU
c - Number of non-whitespace characters
Number of words
f
Find text
Replace all !'s
s - Shorten spaces
r
Quit
(3) Implement the ExecuteMenu() function that takes 2 parameters: a character representing the user's choice and the user provided
sample text. ExecuteMenu() performs the menu options, according to the user's choice, by calling the appropriate functions described
below.
(4) In the main() function, call PrintMenu() and prompt for the user's choice of menu options for analyzing/editing the string. Each option is
represented by a single character.
If an invalid character is entered, continue to prompt for a valid choice. When a valid option is entered, execute the option by calling
ExecuteMenu(). Then, print the menu, and prompt for a new option. Continue until the user enters q. Hint: Implement Quit before
implementing other options.
Ex:
MENU
c - Number of non-whitespace characters
w - Number of words
f - Find text
r - Replace all !'s
s - Shorten spaces
q - Quit
Choose an option:
