Latihan

This document outlines algorithms for displaying iterative outputs, calculating student scores, and computing electricity costs based on specified usage tiers. It includes pseudocode examples for iteration and input handling, demonstrating how to use loop structures effectively. The algorithms take user inputs for scores or meter readings, calculate the average or total cost based on defined criteria, and then display the results. Each example clarifies the flow, making it suitable for students learning algorithm concepts.

  6. Write the algorithm to calculate cost of electricity with following constraints : (KWHs) Rate 0 - 500 2000 501 - 1000 2000 + 0.03 * per KWH over 1001 3500 + 0.02 * per KWH Enter the values of previous month meters, current month meter, and then displays the total cost which would exist.

  7. The structure of the FOR-TO-DO statement FOR counter variableinitial_valueTO final_value program statement ENDFOR

  8. START {initialize} Counter >= initial_value AND counter <= final_value ? action END Flowchart FOR-TO-DO No yes

  9. Example 1 Flowchart START Pseudocode FOR x1 TO 5 DO output (x) ENDFOR x >=1 AND x <= 5 ? No yes output (x) END

  10. Example 2 Pseudocode OUTPUT('before loop starts') FOR i = 1 TO 5 DO OUTPUT('iteration number ',i) ENDFOR OUTPUT('after loop ends')

  11. Execution • generates the output

  12. Example 3 FOR i  1 TO 5 DO Output (‘*’) {action statement} ENDFOR {end loop} The result of program : * * * * *

  13. Example 4 • Program with enter the value of 3 student’s scores : Pseudocode FOR i  1 TO 3 DO Output (‘Score student no-‘,i,’ is:’) Input (score) ENDFOR • Execution : • Score student no-1 is : __ • Score student no-2 is : __ • Score student no-3 is : __

  14. Example 5 • Average of 3 numbers number  0 {initialize} FOR i  1 TO 3 DO Input (x) {input value of x} number  number + x {sum of x variables} ENDFOR average  number/ 3 {calculate the average} Output (average)
