Answers:

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.



An ARRAY is a collection of similar data types.For eg.
int a[5];
An integer type array of size 5 is created in memory.
A STRING is an array of characters.
xFor eg..
char a[5];
a string is usually enclosed in double quotes.
