Preprocessor | MCQs

Explanation

#include <stdio.h> is a compiler directive used to include the standard input-output library before compilation.

It tells the compiler to insert the contents of the specified file into the program.

Explanation

#define PI 3.14

This is the correct syntax for defining a constant using the C preprocessor directive.

It replaces every instance of PI with 3.14 before compilation begins.

Explanation

In C programming, preprocessor directives (like #include or #define) begin with the # symbol.

These directives are processed before the actual compilation of code starts.
