Creation and use of strings in C++<\/span><\/p>\n

C++ provides following two types of string representations:<\/p>\n

\n
• \n

  The C-style character string.<\/p>\n<\/li>\n

• \n

  The string class type introduced with Standard C++.<\/p>\n<\/li>\n<\/ul>\n

  The String Class in C++:<\/h2>\n

  The standard C++ library provides a\u00a0string<\/strong>\u00a0class type that supports all the operations mentioned above, additionally much more functionality. We will study this class in C++ Standard Library but for now let us check following example:<\/p>\n

  At this point, you may not understand this example because so far we have not discussed Classes and Objects. So can have a look and proceed until you have understanding on Object Oriented Concepts.<\/p>\n
