What is the difference between []int and int[]

Question

When I want to implement a function in C++ , if it matters to receive the int array in the following cases?

void fn1(int []a) {
  a[0] = 1;
}

void fn2(int a[]) {
  a[0] = 1;
}

C++ and Java are two different languages. Which one are you actually interested in? — Jon Skeet, Feb 18 '13 at 08:11
Yes it matters. The syntax for arrays in Java & C++ are different. — Austin Brunkhorst, Feb 18 '13 at 08:11
Java would prefer former (atleast stylistically), c++ latter, but it is merely for appearance in c++ anyway — Karthik T, Feb 18 '13 at 08:12
I don't see a `[] int` anywhere except in the title of this question... — glglgl, Sep 15 '15 at 12:49

In Java, there is no semantic difference.

In C++, the first syntax is invalid.

Well, the question is not clear.. Whether to receive the int array or not, it depends on the logics of your method. In Java it is better to write a[], but you can write either way.

Also, look over here - pass array to method Java
