Need help, (x)++

Question

int x = 42;
do {
Console.WriteLine(x);
x++;
} while(x < 10);
I don’t really understand the «x++;» what does it do?

Answer 1

it is the same as "x=x+1", you actually adding 1 to your variable. so in your case x = 42 + 1

Answer 2

Just faster way to write x=x+1

Answer 3

x++ means add number 1to your int ex( 42+1)
but ++x. or x--means substruct 1 ex(42_1)
