Question
The macro __FILE__
expands to the name of the current input file, in the form of a C string constant.
True/False
Solution
True. The macro __FILE__
is a predefined identifier in C and C++ programming languages that is typically used for debugging purposes. When used within a source file, it expands to a string literal that contains the name of that file. This is particularly helpful for developers when they want to include the file name in error messages, log outputs, or debugging information.
For example, if you have a file named example.c
, when you use printf("File: %s", __FILE__);
, it would output File: example.c
. This can provide context for debugging by indicating which file the code is coming from, especially in larger projects with multiple source files.
In summary, __FILE__
is indeed a macro that expands to the name of the current input file represented as a C string constant, making the statement true.
