When terminating a string, it seems to me that logically char c=0 is equivalent to char c='\0', since the "null" (ASCII 0) byte is 0, but usually people tend to do '\0' instead. Is this purely out of preference or should it be a better "practice"?
What is the preferred choice?
EDIT: K&R says: "The character constant '\0' represents the character with value zero, the null character. '\0' is often written instead of 0 to emphasize the character nature of some expression, but the numeric value is just 0.

Strings are actually one-dimensional array of characters terminated by a null character '\0'.
\0 is zero character. In C it is mostly used to indicate the termination of a character string. Of course it is a regular character and may be used as such but this is rarely the case. The simpler versions of the built-in string manipulation functions in C require that your string is null-terminated(or ends with \0 ).
it is used to show that the string is completed.it marks the end of the string. it is mainly used in string type.by default string contain '\0\ character means it show the end of the character in string. end of the array contain ''\0' to stop the array memory allocation for string name.
All character strings are terminated with a null character. The null character indicates the end of the string. Such strings are called null-terminated strings.

Putting it down as char c = 0; could mean that you intend to use it as a number (e.g. a counter). '\0' is unambiguous.
