Which is not a preprocessor directive of C-language?

C preprocessors can have compiler specific features.Question 7Answera.Trueb.False

Let us try to understand the basic structure of a simple C program.The C source code given below prints "Hello!" to the console.#include <stdio.h>void main() { printf("Hello!");}The first line of the program #include <stdio.h> has three parts:The # character is called the preprocessor directiveinclude is a commandstdio.h is the name of the header file that we are trying to includeA header file usually contains useful predefined functions.A preprocessor directive is executed before the compilation is done. We shall learn more about the preprocessor in later sections.Note: Preprocessor directives are lines included in a program that begin with the character #, which make them different from a typical source code text. They are invoked by the compiler to process some programs before compilation.The #include <stdio.h> preprocessor command includes the contents of the file stdio.h into our program, which makes the different I/O functions like printf(),scanf(), etc.. available for use.Click on Live Demo to know about the preprocessor command #include.The second line of the program void main() contains two parts:void in English means empty or nothing. In our program's context, void is the return type. It means that the function main() returns nothing.main() is a function (also called a subroutine) which is called by the operating system. main() is the starting point of execution in any C program.printf() is a function which is used to print the text specified within double-quotes to the standard output device ( i.e, Console/Monitor).The executable statements, which in this case, is a call to printf() function, must be enclosed within an open brace { and a close brace }.Select all the correct statements from the given statements:#include is a preprocessor command.Header files contain functions that are automatically generated by machines.C program can run without main() function.printf("CodeTantra"); statement prints CodeTantra on the console.
