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...

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. read less

String is a type of array that store characters. But an array can store integers, float, characters etc. We do not need to define the size of a string but in case of arrays, we need to.

C and linux Expert

Strings are similar to arrays with just a few differences. Usually, the array size is fixed, while strings can have a variable number of elements. Arrays can contain any data type (char short int even other arrays) while strings are usually ASCII characters terminated with a NULL (0) character.
