Thread: array as an argument

Say in main I have:

PHP Code:

int nums[5];

set_numbers(nums); 


and I have a function called set_numbers() where I want to set the values for the numbers in the array:

PHP Code:

void set_numbers(int n[])
{
     n[0] = 1;
     n[1] = 2;
     n[2] = 3;
     n[3] = 4;
     n[5] = 5;
} 


that code works, but everywhere I read that you have to pass arrays by reference, and when I try to do that I get an error. Whats wrong with doing it how I'm doing it now, and how do I pass it by reference instead?
