Why did prefix override the condition?

Question

static void Main(string[] args)
{
int num = 1;
while(num < 6)
{
Console.WriteLine(num++);
//output:
1
2
3
4
5

static void Main(string[] args)
{
int num = 1;
while(num < 6)
{
Console.WriteLine(++num);

/output
2
3
4
5
6 //why this 6, when the condition is <6

Answer 1

Lets focus on this :
static void Main(string[] args) { int num = 1; while(num < 6) { Console.WriteLine(++num); }

When num equals to 5, it can go into the loop right? Once it is inside the loop, it will print out (num + 1) because its a prefix. Hence, it will print out 6.
