Question

intx = 2, y = 50;
do
{
++X
Y- = x++
}
while (x <= 10);
System.out.println(y);

How many times will the following loop executed??? Please explain
.
​

Answer 1

take one more variable count=0;

after Y-=X++ write

count=count++

after System.out.println(y);

print the count value, u vl get the no.of times the loop executes

Answer 2

Here is your Answer:

This loop will execute 5 times

Explanation:

++x means prefix where the number is incremented by 1.

x++ means postfix where the value of x is printed and then incremented by 1 in memory.

in do-while you can see both prefix and post fix operation are present so when the loop executes first time the value of x is incremented to 3 and 4 by two operator, 2nd time the value  x is incremented to 5 and 6, 3rd time 7 and 8, 4th time 9 and 10 since the while loop condition is (x <= 10) where 10 is equal to 10 so it will execute one more time that is 5th time the value of x will be 11 and 12.

this clearly explains your question that the loop will be executed 5 times.
