#include <iostream>
#include <string>//this is for the function strlen()

void swap(char *thisChar, char *withThisChar) {//this will swap and change the actual word
char temp = *thisChar;
*thisChar = *withThisChar;
*withThisChar = temp;
}

char word[] = "civic";
int nChars = strlen(word);//strlen() is part of: #include <cstring>. It returns the length of a string
char *pWordStart = word;
char *pWordEnd = word + nChars - 1;

int main() {
string saveWord = word;
while (pWordStart < pWordEnd) {
swap(pWordStart, pWordEnd);
pWordStart++;
pWordEnd--;
}
string reversedWord = word;

if (saveWord == reversedWord) {
cout << saveWord << " is a palindrome!" << endl;
} else
cout << "'" << saveWord << "' is not a plindrome :(" << endl;

return 0;
}
