Vala. Compare Two Arrays, if Equal

This Vala snippet provides an utility function array_equals, which will compare two arrays.

Function: array_equals

With the function array_equals (see bellow) you can find out, if two arrays are equal to one another. The arrays will be considered equal, if they contain the same number of elements and all corresponding pairs of elements are equal. In other words, the two arrays will be considered equal, if they contain the same elements in the same order. Also the two arrays will be considered equal if both are null.

Use Example

How to use the function array_equals:

// Compare arrays of integers
int[] array_one = {5,2,1,4,5,3,7,9,8};
int[] array_two = {5,2,1,4,5,3,7,9,8};
		
bool result = array_equals(array_one,array_two); // true
		
// Compare arrays of strings
string[] array_three = {"Tom","Jerry"};
string[] array_four = {"Tom","Jerry"};
		
bool result2 = array_equals(array_three,array_four); // true
