What is the difference between Strings and Arrays in c?
There is no difference. A string is just an array of type char. The only real difference is that we do not need to keep track of the length of a string because strings are null-terminated in C. If a string does not have a null-terminator, then it is just an ordinary array of character values.

To denote a string, surrounding a list of characters by double quotes is the typical standard.Strings:* "" * "abc" * "Cows say 'Moo!'" * "http://wiki.answers.com"Numbers are those fun symbols you remember from math class. The confusing part is when a string contains numbers ("123"). Usually a programming language will have a way to convert between a string of numbers and an actual number type, in case you happen to need to do math with the string.
What are the different issues if a string is implemented as a primitive or as a character array?
Even in languages where string is a type, it is still an array of characters. A computer can not represent a string as a primitive type. That said, the difference between using the programming language string object or an array or list if characters will differ based on language. Though in most languages which offer a string type, it would mean that you'd have to implement all the functions provided for you by the type on your own. A string object class simply provides a series of utility functions to manipulate a character array within.
Diff between string and array?
String and array are not related to one another so they have many differences. a. A string is used to hold alpha numeric values inside it b.
