    string stops at first letter

    Hey, can anyone help me figure out why the program keeps stopping with the first letter instead of following through the string??
    #include <iostream>
    #include <string>
    using namespace std;
    bool isVowel (char);
    string noVowelString (string);
    int main ()
    	string str;
    	cout<<"Enter a sentence: ";
    	cout<<"The sentence with the vowels removed is "<<noVowelString(str)<<endl;
        return 0;
    bool isVowel (char ch)
    	switch (ch)
    	case 'A':
    	case 'E':
    	case 'I':
    	case 'O':
    	case 'U':
    	case 'a':
    	case 'e':
    	case 'i':
    	case 'o':
    	case 'u':
    		return true;
    		return false;
    string noVowelString (string tStr)
    	string :: size_type len=tStr.length();
    	bool foundVowel = false;
    	string :: size_type i;
    	for (i = 0; i < tStr.length; i++)
    		if (isVowel (tStr[i]))
    			tStr.erase (i, 1);
    			foundVowel = true;
    			tStr = tStr.substr (i, 1);
    	return tStr;

    You can't use the extraction operator>> to extract sentences. The extraction operator>> stops processing the string when it encounters a white space character. If you want your string to contain white space characters I recommend you try using the getline() function.

    You're also modifying the string as you iterate over it, which spells disaster.
