If he was looking for all punctuation, then that'd work, but he specifies five specific characters he's looking for.

I still favor my find_first_of approach(), regarding the symbols... its flexible, also could be used for digits and alphas (although that'd be overkill since isdigit and isalpha is available).

Regarding my above isSymbol function, it would be as easy as:

(Toggle Plain Text)

if (isSymbol(myChar))
   symbolCount++;

(If you like, simply assume that, if a character is not a digit or puncuation, it is a letter. Also, just use the most common puncuation symbols (. , ? ! : ;)).

Guess that's interpretable a couple different ways. Anyway, I saw his list. He obviously needs to use the "isWinkyEmoticon" function.

You showed sufficient effort, and I became bored... try something like this:

(Toggle Plain Text)

 
#include <iostream>
#include <string>
#include <cctype>
#include <conio.h>
 
using namespace std;
 
bool isSymbol (char x);
void ParseInput (string input);
 
// counters
int alpha = 0, digit = 0, symbol = 0;
 
int main (void)
{
	char myInput[250]; 
	cout << "Enter characters: " << endl;
	cin.getline(myInput, 250);
 
	cout << myInput << endl; 
	ParseInput (myInput);
 
	cout << "Digits: " << digit << endl;
	cout << "Alpha: " << alpha << endl;
	cout << "Symbols: " << symbol << endl;
 
	system("PAUSE");
 
	return 0;
}
 
void ParseInput (string input)
{
	 int i = 0;
	 for (i = 0; i < input.length(); i++)
	 {
		 if ( isalpha(input.at(i)) )
			alpha++;
		 else if ( isdigit(input.at(i)) )
			digit++;
		 else if ( isSymbol(input.at(i)) )
			symbol++;
	 }
}
bool isSymbol (char x)
{
	 string SYMBOLS = "X ~`!@#$%^&*()_+-={}[]:\";'<>?,./|";
	 bool result = false;
	 int location = 0;
 
	 location = SYMBOLS.find_first_of(x);
 
	 if (location > 0)
		result = true;
 
	 return result;
}
