Chapter 21, Problem 21.16E

Program Plan Intro

Working with Palindromes

Program Plan:

• Include the required header files.
• Define the “main” function.
• Accept a string sentence in line string variable.
• Create an integer variable counter and assign it to 0.
• Create a vector of string to save tokens.
• Create an object of stringstream class.
• Use a loop to tokenizing with respect to space ' '.
• Use a loop to iterate through vector tokens.
• Create a string object str.
• Transform all the tokens into lower case.
• Assign the value of current token to str.
• Reverse the value of str.
• Compare the reversed str value with current token to check whether it is a palindrome or not.
• If it is a palindrome display the current token.
• Increment the counter variable.

• Display the total number of palindromes in the sentence.
