String Constants

A string constant consists of zero or more characters enclosed in quotation marks. Several string constants are given below:

"Welcome to C Programming"
" "
"a+b\n"
"Error\a\a\a"

There is a difference between the constant 'A' and "A" in C. The first 'A' is a character constant, while the second "A" is a string constant. The notation 'A' represents a constant occupying a single byte containing the ASCII code of the character A. The notation "A", on the other hand, is a constant that occupies two bytes: one for the ASCII code of A and another for the null character with the value 0, which terminates the string.
