in this statement operator >> is  ,which is also called extraction operator , use to read a string from keyboard and then it will  place it in the string  variable which we declare as  std.

Insertion  operator ( >>)  knows how to deal with strings; it understand that they are arrays of characters . Each characters in string take 1 byte of memory . An important aspect of strings is that they must terminate with a byte containing 0. This is frequently characterized by characters constant 0, which is a characters with an ASCII value of 0. This terminating zero is called null characters. When the (<<) operator shows string, it displays characters till it meets null character .
