我正在製作一個程序來轉換電話號碼,刪除所有分隔符,並將其與原始數字進行比較以確定它是否是迴文。它還會將電話號碼轉換爲帶逗號的整數。我有幾個問題。我收到錯誤,不知道爲什麼。此外,它不會正確確定該數字是否是迴文。任何幫助,將不勝感激。如何使用字符串標記器和緩衝區。
//Phone String Palindrome Conversions
//This program will turn a phone number around and check to see if it is a palindrome
//This program will remove all deasdspace and symbols from the phone number
//This program will reverse the string and compare it to the original
//This program will put a phone number in a long intiger format
