 Hello friends, I am Sanjay Gupta. In this video, I am going to demonstrate you how to use continuation operator in macro in C programming. Before starting, you can note how you can search my YouTube channel. You can type my name Sanjay Gupta in YouTube. My channel will be available there. You can watch various programming related videos here. Now I am going to implement the demonstration so that you can understand how we can use continuation operator in macro in C programming. So first I have included a header file that is stdio.h. Now I am going to define a macro which will check whether a number is positive, negative or zero. So here name of macro is POS energy ZERO that is positive, negative, zero. It will receive a parameter and now I have to define its replacement token list. So for that purpose, I have to implement various if else statements. So first if statement is n greater than zero, if it is true, then it will print number is positive. Otherwise else if I have to implement n less than zero, then it will print number is negative. So now you can see this single statement is very lengthy statement. Now if you want to implement this single statement in multiple lines, then to break this macro in multiple lines, you can use this continuation operator. So the continuation operator is used to write macro in more than one statements and that macro will remain like a single statement while you are using this continuation operator. So here I am using continuation operator. So you can see the statements are still in green color because they are right now with hash defined statement. So whenever you want to implement multiple statements for macro, you can use this continuation operator. So third print f will be printing number is zero. So this way I have implemented three statements in this macro, but all three statements will work like a single statement because I have used continuation operator. So don't write all the statements in a single line because that single line will not be in readable format. So you can break those single statement into multiple statements with continuation operator in C programming. Now I am going to define main function so that I can use this macro. So with the help of this print f statements, the entered value will be stored inside and variable and at line number 11, I have used macro. So this macro will be replaced with a replacement token list which is available at line number three, four and five. And this replacement token list is implemented with the help of continuation operator. Now I am going to execute this code. It is asking for a number. I am entering five. You can see the output. It is showing number is positive. So it means program is working properly. Now if I remove this continuation operator, you can see line number four and five are in now different colors. It is not in green color. So that's what it means a line number four and five are not part of line number three. That is a macro. So if you want to make line number four and five as a part of macro, then you have to use continuation operator at the end of line number three and four. So this way I have demonstrated you how you can use continuation operator to break macro in multiple lines. I hope you have understood whatever I have demonstrated you in this video.
