Pre-Requisite : Read (Campbell, Information Technology for CSEC – 3rd Edition, 2020, pp. 272-273)
Observe the attached flowgorithm file, or the pseudocode below:
Start
// Here we set up 2 numbers to experiment with our relational operators....
FirstNum = 7
SecondNum = 5
// Comparison: First number is greater than second number
greaterThan = FirstNum > SecondNum
output "' " + FirstNum + " is greater than " + SecondNum + " ' evaluates to " + greaterThan
// Comparison: First number is greater or equal to second number
greaterThanOrEqualTo = FirstNum >= SecondNum
output "' " + FirstNum + " is greater than or equal to " + SecondNum + " ' evaluates to " + greaterThanOrEqualTo
// Comparison: First number is equal to second number
equalTo = FirstNum = SecondNum
output "' " + FirstNum + " is equal to " + SecondNum + " ' evaluates to " + equalTo
// Comparison: First number is not equal to second number
notEqualTo = FirstNum ≠ SecondNum
output "' " + FirstNum + " is not equal to " + SecondNum + " ' evaluates to " + notEqualTo
// Comparison: First number is less than second number
lessThan = FirstNum < SecondNum
output "' " + FirstNum + " is less than " + SecondNum + " ' evaluates to " + lessThan
// Comparison: First number is less than or equal to second number
lessThanOrEqualTo = FirstNum <= SecondNum
output "' " + FirstNum + " is less than or equal to " + SecondNum + " ' evaluates to " + lessThanOrEqualTo
Stop
The flowgorithm file or the pseudocode above should output:
‘ 7 is greater than 5 ‘ evaluates to true
‘ 7 is greater than or equal to 5 ‘ evaluates to true
‘ 7 is equal to 5 ‘ evaluates to false
‘ 7 is not equal to 5 ‘ evaluates to true
‘ 7 is less than 5 ‘ evaluates to false
‘ 7 is less than or equal to 5 ‘ evaluates to false
Task:
In your notebook or personal notes, determine the output of the algorithm when FirstNum and SecondNum Is updated as follows:
- FirstNum=6 , SecondNum=7
- FirstNum=7 , SecondNum=7
- FirstNum=6 , SecondNum=7
- FirstNum= -6 , SecondNum= -7
