        Third day at uki.

we learnt basic commands of linux.

     
       ls-list
       cd- change directly
       cd ..-go to back path
       mkdir foldername- create a folder
       rmdir foldername - remove the folder
       touch filename.txt - create a textfile
       rm filename.txt - remove the textfile
      pwd - path working directly
      mv oldfilename.txt newfilename.txt - rename the textfile

we leant about flowcharts and pseudo code.
       operations of a variable:
             1.assignment operation.
             2.read operation.

       advantage of write pseudo code:
             easy to read and write.
        
       input - read/get/input.
       output - write/display/output.
     
       assignment operation
             x=3

             assign 3 to x

             set x equal to 3

       three types of flowcharts:

         1.sequence

             set of instructions.

             process in order.

         2.selection 

             condition(if,else)

    

         3.repetation(while)
