:D TLE @ 4:37 AM


What did I learn in our TLE class?

Asking me this question needs a simple but a brilliant answer. Of course I've learned lots of things thanks to our hardworking teacher :)

Fist of all I've learned what's algorithm and flowcharting.

Algorithm- In mathematics, computing, linguistics, and related subjects, an algorithm is a finite sequence of instructions, an explicit, step-by-step procedure for solving a problem, often used for calculation and data processing. It is formally a type of effective method in which a list of well-defined instructions for completing a task, will when given an initial state, proceed through a well-defined series of successive states, eventually terminating in an end-state.

Flowcharting- represents an algorithm or process, showing the steps as boxes of various kinds, and their order by connecting these with arrows. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields.

I also learned the Program Development Cycle.
step 1: Review of programming specifications.
  • Input specifications
  • Output specifications
  • File specifications
  • Process specifications
step 2: Program Design







Example of a Program Design

















step 3: Program coding
  • Review of the program
  • Entering the program
  • Saving the program
  • Executing the program
  • Interpreting the program
step 4: Program Testing
  • Desk Checking
  • Encoding
  • Generation of error list
step 5: Program Documentation

I also learned the different symbols used in flowcharting and of course I learned how to make a flow chart.
