                #include    
                    int main(){    
                        //printing information    
                        printf("Hello C");    
                    return 0;  
                    }

Even you can place the comment after the statement. For example:

            
                printf("Hello C");//printing information

Multi-Line Comments

Multi-Line comments are represented by slash asterisk * ... *. It can occupy many lines of code, but it can't be nested. Syntax:

            
                /*  
                code 
                to be commented 
                */

Let's see an example of a multi-Line comment in C.

                #include    
                    int main(){    
                        /*printing information   
                          Multi-Line Comment*/  
                        printf("Hello C");
