Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Rapira.

What does this simple Rapira code do?
PROC main()
  PRINT('Hello, World!')
This code prints the string 'Hello, World!' to the console.
What will be the output of this Rapira code?
PROC main()
  VAR x
  x := 5 + 10
This code will output the number 15, which is the result of the addition operation 5 + 10.
What does this Rapira code do with the array?
PROC main()
  VAR arr
  arr := [1, 2, 3, 4, 5]
This code prints the length of the array 'arr', which is 5.
What does this Rapira code do related to threading?
PROC main()
  VAR x
  x := 0
  FOR i FROM 1 TO 1000 DO
    x := x + 1
This code increments the variable 'x' by 1 in a loop that runs 1000 times, and then prints the final value of 'x'. However, Rapira does not support multi-threading or concurrency, so this operation is not thread-safe.
