INTERVIEW QUESTIONS C STRINGS IN C DETAILS

Question: What is the difference between a string and an array?

Answer: An array is an array of anything. A string is a specific kind of an array with a well-known convention to
determine its length.
There are two kinds of programming languages: those in which a string is just an array of characters, and those
in which it’s a special type. In C, a string is just an array of characters (type char), with one wrinkle: a C string
always ends with a NUL character. The “value” of an array is the same as the address of (or a pointer to) the
first element; so, frequently, a C string and a pointer to char are used to mean the same thing.
An array can be any length. If it’s passed to a function, there’s no way the function can tell how long the array
is supposed to be, unless some convention is used. The convention for strings is NUL termination; the last
character is an ASCII NUL (‘’) character.
