TIC English: Development of algorithms

Elaborate the next sequential algorithm:

1. Determinate the Perimeter of a rectangle

1.- Start

2.- Input b, h

3.- Calculate p

P = (2b) + (2h)

4.- Print Perimeter P

5.- End

2. Convert any quantity from pesos to dollars.

1.- Start

2.- Input Pesos, Price of Dollar

3.- Calculate Pesos to Dollars

Dollar = Pesos/Price of Dollar

4.- Print Dollar

5. End

3. Determinate the area of a pentagon

1.- Start

2.- Input l, a, p

3.- Calculate p

P = l*5

4.- Print Perimeter P

5.- Calculate area

A = (P)a/2

6.- Print Area A

7.- End

4. Determinate the final speed of an automobile if its initial speed is zero and its acceleration is 0.8 m/ s2 and the time passed is 30 seconds

1.- Start

2.- Input a, t

3.- Calculate Fs

Fs = (0.8m/s2 * 30)

4.- Print Final speed Fs

5.- End

Elaborate the next conditional algorithm

1. Determines whether a person is entitled to vote in elections. Note considers the age of entitlement to vote is equal to or greater than 18 years.

1.- Start

2.- Ask the age of a person

3.- Compare the age (Age is greater or equal to 18 years old) then

4.- Yes: The person can vote, go to step 6

5.- No: The person can not vote

6.- End

2. Determine whether a student has passed or failed the course of Information and Communication Technology 2, based on three exams. Note: You must first calculate the average and based on this calculation to determine if this approved or not.

1.- Start

2.- Input Ex1, Ex2, Ex3

3.- Calculate sum of exams

S = (Ex1) + (Ex2) + (Ex3)

4.- Print Sum S

5.- Calculate Average

A = S/3

6.-Print Average A

7.- Passed: A > = 70, go to step 9

8.- Failed: A < 70

9.- End.

3. Determinate if any number is positive, negative or zero.

1.- Start

2.- Input x

3.- Zero: x=0, go to step 6

4.- Positive: x>0, go to step 6

5.- Negative: x<0

6.- End
