What is your question?

[elmessican]

how can i make the menu work


i have this
#include <iostream>
#include <string>
using namespace std;

int GetNumOfNonWSCharacters(string);
int FindText(string, string);
int ReplaceExclamation(string);
int ShortenSpace(string);
int GetNumOfWords(string);


///menu fucntion

void PrintMenu() {


cout << "MENU" << 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;

}


int main() {


const int GetNumOfNonWSCharacters = 'c',
FindText = 'f',
ReplaceExclamation = 'r',
ShortenSpace = 's',
GetNumOfWords = 'w';
char option;
string userInput;

cout << "Enter a sample text: " << endl;
getline(cin, userInput);
cout << "You entered: " << userInput << endl;
cout << endl;

PrintMenu();

do {


cin >> option;

if (option == 'q'){
break;
}

switch (option) {
case GetNumOfNonWSCharacters:
int GetNumOfNonWSCharacters();
break;

case GetNumOfWords:
int GetNumOfWords();
break;

case FindText:
int FindText();
break;

case ReplaceExclamation:
int ReplaceExclamation();
break;

case ShortenSpace:
int ShortenSpace();
break;

case 'q':

break;

}
}while (option != 'q');

return 0;
}

/////////num of words///////////
