x = 42; int num = 0; while (num <3) Consele.writeline (x); num++; int x = 42; is just an int with an asigned value of 42 int num=0; is what initiate the count for the while loop while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false consele.writeline (x) will display 42 while num < 3 num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false. so the consele.write will write 42 three times. x=42, remember the (x)
