Operate with numbers
What will be the output of the following program?
public class Operation {

    public static void main(String[] args) {
        int num1 = 0;
        int num2 = 0;
        for (int i = 0; i < 5; i++) {
            if ((++num1 > 2) && (++num2 > 2)) {
                num1++;
            }
        }
        System.out.println(num1 + " and " + num2);
        System.out.println(num2 | 12);
    }
}

A. 5 and 2 
14
B. 5 and 3
15
C. 6 and 3

since the loop is repeated for 4 times and...and addition of num1++ takes two times...soo num1 is 6 and nums takes place for 4times

answer is C because after executing the loop the values of num1 and num2 are 6 and 3 and operation of bitwise OR operator gives 15

Ans is c.. loop vl excute 3 times so num2=3, num1 is increasing twice so num1=6.. num2 | 12= num2+12=15

The answer is option C,,intially the values of Num1 and Num2 is 0, in the for loop it repeats till i<5,so as if condition is given ++num1 if >2 n ++num2if >2 then num1++ ,1st num1 will be 0, thus do ++num1 in IF condition,it is not >2,does the same til num1>2,now num1=3 and num2 =0,,nw it satisfies,,does ++num1 n ++num2 til i<5...now d values r num1=6,num2=3...thus pritns 6 and 3 in 1st s.o.p then...in 2nd s.o.p it takes 0011 | 1100 it gives 15...hence C is d answer :)

answer is c

answer is c..num2 does not get incremented until ++num1>2 is true...so the ending values vl bcum  5 n 3 n finally as both the conditions are true num1 is incremented in if condition..finally 6 n 3 are the values..3 | 12 using bit or 0011 | 1100 gives 1111 i.e, 15
