Week 5 Activity – Numbers Squared

Week 5 Activity – Numbers Squared

-------------------------------------------------

TCO #4 – Given a simple business problem that requires one or more decisions, create a solution algorithm that uses decisions with logical and relational expressions.

-------------------------------------------------

TCO #5– Given a simple business problem that requires iteration, create a solution algorithm that employs loops.

-------------------------------------------------

TCO #9 – Given a program with logic errors that is intended as a solution to a simple business problem, employ debugging diagnostics to remove and correct the errors.

Assignment (part A): Your goal is to solve the following simple programming exercise. Using a FOR loop, write an algorithm that displays the squares of the numbers 1 to 10 to console output. Thought provoking question: Do you need to accept input?

Assignment (part B): Using a pretest WHILE loop, write an algorithm that displays the squares of the numbers 1 to 10 to console output.

No actual input is needed as long as the variable is declared.

Input | Processing | Output |

Numbers 1 through 10 | Find square root of each number | Square roots of numbers 1 through 10 |

Part A Pseudocode:

Begin

Declare Real number=1

Declare Real square=0

Display “Discovering the square of number 1 through 10”

FOR number 1 through 10

Set square=number^2

Display “The square of “ + number + “ is “ + square

ENDFOR

Display “End of display”

End

Part B Pseudocode

Begin

Declare Real number=1

Declare Real square=0

Display “Discovering the square of number 1 through 10”

DO WHILE number <=10

Set square=number^2

Display “The square of “ + number + “ is: “ + square

Set number=number+1

ENDDO

Display “End of display”

End
