2)The main() calls the deleteduplicate(char *s, char c)by passing the string and the duplicate character as arguments to the function to delete the repeated elements from the string. The function deleteduplicate(char *s,char c) a)k=0, the for loop iterates through the string b)If the...
String in c are defined like arrays ending with \0. In c++ on the other hand std::string is preferred. You cannot normally delete an element of an array but instead you can do this: either push all elements one position to the left and don't use the last position OR create a new ...

1.Character 是进行单个字符操作的, 2.String 对一串字符进行操作。不可变类。 3.StringBuffer 也是对一串字符进行操作,但是可变类。 String: 是对象不是原始类型. 为不可变对象,一旦被创建,就不能修改它的值. 对于已经存在的String对象的修改都是重新创建一个新的对象,然后把新的值保存进去. ...
