Difference between int[] array and int array[]

Question

I have recently been thinking about the difference between the two ways of defining an array:

1. int[] array
2. int array[]
<

Answer 1

As already stated, there's no much difference (if you declare only one variable per line).

Note that SonarQube treats your second case as a minor code smell:

Array designators "[]" should be on the type, not the variable (squid:S1197)

Array designators should always be located on the type for better code readability. Otherwise, developers must look both at the type and the variable name to know whether or not a variable is an array.

Noncompliant Code Example

int matrix[][];   // Noncompliant
int[] matrix[];   // Noncompliant

Compliant Solution

int[][] matrix;   // Compliant
