- 2. Pseudocode • Pseudocode is a compact and informal high-level description of a program using the conventions of a programming language, but intended more for humans. • There is no pseudocode standard syntax and so at times it becomes slightly confusing when writing Pseudocode and so let us understand pseudo code with an example.
- 3. Pseudecode Syntax • FOR THOSE TUTORIALS I'LL USE THAT SYNTAX • INPUT – indicates a user will be inputting something • OUTPUT – indicates that an output will appear on the screen • WHILE – a loop (iteration that has a condition at the beginning) • FOR – a counting loop (iteration) • REPEAT – UNTIL – a loop (iteration) that has a condition at the end • IF – THEN – ELSE – a decision (selection) in which a choice is made • any instructions that occur inside a selection or iteration are usually indented
- 4. Pseudocode & Flowchart Example 1 Add Two Numbers 1 2 3 4 5 6 7 8 9 BEGIN NUMBER s1, s2, sum OUTPUT("Input number1:") INPUT s1 OUTPUT("Input number2:") INPUT s2 sum=s1+s2 OUTPUT sum END
- 5. Pseudocode & Flowchart Example 2 Calculate Perimeter of Rectangle 1 2 3 4 5 6 7 8 9 BEGIN NUMBER b1,b2,area,perimeter INPUT b1 UNPUT b2 area=b1*b2 perimeter=2*(b1+b2) OUTPUT alan OUTPUT perimeter END
- 6. Pseudocode & Flowchart Example 3 Find Perimeter Of Circle using Radius 2 3 4 5 6 BEGIN NUMBER r, perimeter INPUT r area=3.14*2*r OUTPUT perimeter END
- 7. Pseudocode & Flowchart Example 4 Calculate sales taxes 3 4 5 6 7 8 9 10 11 12 13 14 15 BEGIN NUMBER price, tax, taxRate, total OUTPUT "Enter Product Price" INPUT price OUTPUT "Enter tax rate amoung 1 and 100" OKU taxRate tax= price* taxRate/100 total= price + tax OUTPUT "Product tax="+tax OUTPUT "Product total price ="+total END
- 8. Pseudocode & Flowchart Example 5 Check a Number is Positive or Negative 5 6 7 8 9 10 11 12 13 14 15 16 BEGIN NUMBER num OUTPUT "Enter a Number" OKU num IF num>0 THEN OUTPUT "Entered number is positive" ELSE IF num <0 THEN OUTPUT "Entered number is negative" ELSE OUTPUT "Entered number is zero" ENDIF END

Pseudocode & Flowchart Example 6 Find the biggest of three (3) Numbers 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 BEGIN NUMBER num1,num2,num3 INPUT num1 INPUT num2 INPUT num3 IF num1>num2 AND num1>num3 THEN OUTPUT num1+ "is higher" ELSE IF num2 > num3 THEN OUTPUT num2 + "is higher" ELSE OUTPUT num3+ "is higher" ENDIF END
- 10. Pseudocode & Flowchart Example 7 Print Numbers from 1 to 100 2 3 4 5 6 7 8 BEGIN NUMBER counter FOR counter = 1 TO 100 STEP 1 DO OUTPUUT counter ENDFOR END
- 11. Pseudocode & Flowchart Example 8 Read 50 numbers and find their sum BEGIN NUMBER counter, sum=0, num FOR counter=1 TO 50 STEP counter DO OUTPUT "Enter a Number" INPUT num sum=sum+num ENDFOR OUTPUT sum END
- 12. Pseudocode & Flowchart Example 9 Read 10 numbers and find sum of even numbers 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 BEGIN NUMBER counter, sum=0, num FOR counter=1 TO 10 STEP 1 DO OUTPUT "Enter a Number" INPUT num IF num % 2 == 0 THEN sum=sum+num ENDIF ENDFOR OUTPUT sum BİTİR
