Chapter 9, Problem 3P

Palindrome testing with pointers

This Practice Program requires that you read the optional section about pointer arithmetic. Complete the function isPalindrome so that it returns true if the string cstr is a palindrome (the same backwards as forwards) and false if it is not. The function uses the cstring library.

bool isPalindrome(char* cstr) { char* front = cstr; char* back = cstr + strlen(cstr)−1; while (front < back) { // Complete code here } return true; }

 Here is a sample main function for quick and dirty testing:

int main() { char s1[50] = "neveroddoreven"; char s2[50] = "not a palindrome"; cout << isPalindrome(s1) << endl; // true cout << isPalindrome(s2) << endl; // false return 0; }
