Comparing hierarchies

Comparing hierarchies

You can use the equal to (=) and not equal to (!=) operators to compare two arrays or two structs.

Comparing arrays

Two arrays are equivalent if the following conditions are true:
  • The array elements are the same data type.
  • The arrays are the same size.
  • The element at each index is the same.
For example, you have the following arrays: 
A = [1, 2, 3]
B = [1, 2, 3]
You can make the following comparison: 
A = B
Both arrays contain integers, the arrays are the same size, and the element at each index is the same such that
A[0]=B[0], A[1]=B[1], and A[2]=B[2]
. The return value is TRUE (1).

Comparing structs

Two structs are equivalent if the following conditions are true for the corresponding struct elements:
  • The elements are the same data type.
  • The elements hold the same data.
Two structs are equivalent even if the elements have different names.
For example, you have the following structs: 
struct1 {
	name:'Paul'
	zip:10004
}

struct2 {
	firstname:'Paul'
	zip1:10004
}
You can make the following comparison: 
struct1 = struct2
The corresponding elements are the same data type and hold the same data, so the return value is TRUE (1).
