Question

What will be the expected output of the following pseudo code? Write exactly what would display when you execute the statements.

Module main()
  Declare Integer a = 5
  Declare Integer b = 2
  Declare Integer c = 3
  Declare Integer result = 0
  Display "The value of result is"
  Display result
  Set result = a + b * c - a
  Display "Changed value is: ", result
End Module

Answer 1

output:

The value of result is

0

Changed value is:6

explanation:

a is initialised with 5

b is initialised with 2

c is initialised with 3

and variable result is initialised with 0

display"The value of result is"

this line enclosed in the double quotes will be printed as it is

therfore initial value of result will be 0 and it will be printed

now the result is set to the expression

a + b * c - a

in which a=5,b=2,c=3

accrding to the bodmas rule

multiplication is done first b*c=2*3=6

since operations done from left to right because +,- are having same precision +is done first

5+6=11

now subraction is done

11-5=6

therefore the new value of result will be updated as 6

and the value after display which is enclosed in double quotes will be printed same and this result is appended after the double quotes seperated by comma

this result will be printed after the double quotes enclosed statement

Changed value is: and the updated value of result i.e 6 is printed
