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.

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. Source: CoolInterview.com

an array is a collection of similar elements which is maintaining under one variable name.
eg.
int a[10];
here the memory is allocating for ten integer variables.
where as in string it is a group of characters maintaining under one variabe name..
eg.
char b[10];
here memery allocating for ten character values..hence we can define the string is also a one type of aray. Source: CoolInterview.com
