Step by Step solution about How to resolve the algorithm Apply a callback to an array step by step in the FutureBasic programming language

Source code in the futurebasic programming language

include "NSLog.incl"

void local fn Callback( n as NSInteger )
  NSLog( @"Square root of %ld = %f", n, sqr(n) )
end fn

void local fn DoIt
  NSUInteger i, count
  CFArrayRef array = @[@1, @2, @3, @4, @5, @6, @7, @8, @9, @10]

  count = len(array)
  
  for i = 0 to count -1
    fn Callback( fn NumberIntegerValue( array[i] ) )
  next
end fn

fn DoIt
