C++

Can some explain why the function isPalindrome_type3 does not delete the white spaces from the string parameter. For example "race car" should come back true for being a palindrome because if you erase the space it is the same word if reveresed. However it doesnt seem to work. The following is my code

#include #include #include #include #include

using namespace std;

void removeCharsFromString( string &str, char* charsToRemove ) { for ( unsigned int i = 0; i

bool isPalindrome_type1(string & aString) //test to see if a string is an exact palindrome { string temp; temp = aString; reverse(temp.begin(), temp.end()); return temp == aString; }

bool isPalindrome_type2(string & aString) //converts all char to lowercase then calls func isPalindrome_type1 { string allLow(aString); transform(aString.begin(), aString.end(), allLow.begin(), ::tolower); return isPalindrome_type1(allLow); }

bool isPalindrome_type3(string & aString) //removes all punctuation and space characters then call func isPalindrome_type2 { string temp(aString); char chars[] = " ,.!?"; removeCharsFromString(temp, chars);

return isPalindrome_type2(temp); }

int main() { string palindrome; cout > palindrome;

if(isPalindrome_type3(palindrome)) { cout

I want the second one to also come back as a palindrome.

thanks
