30Days of Programming

Now I understand that anything I can do with command line If I wanted to create a new folder and access it, then create many files within it, it would be like this These were some basics about the language C

  I can also use the graphics to rename a specific file  We're writing this down The file will be named like this  

To find out how many files I have, I type ls, which is short for list Here the word hello appeared in green, meaning that this file is usable, the file in machine language

  Command Line It is what enables me to create a new file and name it whatever I want, and I can also delete it. To create a new file, we write code If you want to delete it, type rm , short for remove, and it will look like this

  long If the variable is of type long, which is large numbers, it will be printed like this:

letters  Now, if you want to write letters, we will write the code in this image:

decimal numbers Now that I have learned to write a numerical variable, but this was for integers, so I have learned to write decimal numbers, and it will be written in this form
