What's the difference between a String Constant and String Literal in plain C?
This question is similar to another: What's the difference between a string constant and a string literal? ...except that one was regarding Objective-C (using NSString) and not C.
In the C99 Draft from 2007 the term sting literal is used. The term string constant does not appear in the draft at all.
I find string literal to be a good term choice when talking about "foo" (just as 42 is a literal number, "foo" is a literal string).
They are one and the same. Merely a preference in which word you use to describe the string.
The spelling of the second word used to describe the same idea?
I would regard them as the same thing - alternative terms for the same construct.
const char * strConst;
strConst = "Hello World";
In this example
strConst
is a string constant. "Hello World"
is a string literal, and is typically stored in the read only area of the program. 文字和常量意味着相同,这是在源代码中表示固定值的符号。
