require 'chilkat'

arr = Chilkat::CkJsonArray.new()

# Add an empty object at the 1st JSON array position.
arr.AddObjectAt(0)
# Get the object we just created.
# obj is a CkJsonObject
obj = arr.ObjectAt(0)
obj.UpdateString("Name","Otto")
obj.UpdateInt("Age",29)
obj.UpdateBool("Married",false)

# Add an empty object at the 2nd JSON array position.
arr.AddObjectAt(1)
# obj is a CkJsonObject
obj = arr.ObjectAt(1)
obj.UpdateString("Name","Connor")
obj.UpdateInt("Age",43)
obj.UpdateBool("Married",true)

# Add an empty object at the 3rd JSON array position.
arr.AddObjectAt(2)
# obj is a CkJsonObject
obj = arr.ObjectAt(2)
obj.UpdateString("Name","Ramona")
obj.UpdateInt("Age",34)
obj.UpdateBool("Married",true)

# Examine what we have:
arr.put_EmitCompact(false)
print arr.emit() + "\n";

# The output is:

# [
#   {
#     "Name": "Otto",
#     "Age": 29,
#     "Married": false
#   },
#   {
#     "Name": "Connor",
#     "Age": 43,
#     "Married": true
#   },
#   {
#     "Name": "Ramona",
#     "Age": 34,
#     "Married": true
