               printf(“These are steps to run program using Notepad++”);
               return(0);        
         }
  • Save the written program in the directory in which you have installed C language Compiler.
  • To compile the program open command prompt.
  • At the command prompt use cd  command to change directory and move to the location where the program is saved.
  • When you are at the location where the program is saved you are ready to execute the program.
