14. What is the difference between a break statement and a continue statement when they occur in a loop? [2013]
Ans.
break Statement continue Statement
Used to exit from a loop. Used to go to the next iteration in the loop.
for(i=1; i<=5; i++) for(i=1; i<=5; i++)
{ {
if(i%2==0) if(i%2==0)
break; continue;
System.out.print(i); System.out.print(i+ " " );
} }
Output will be: 1 Output will be: 1 3 5
15. How many times will the following loop execute? What value will be returned?
int x = 2, y = 50;
do{
++x;
y -= x++;
}while(x <= 10);
return y; [2013]
Ans. The loop will execute for 5 times.
15 will be returned
16. Rewrite the following program segment using while instead of for statement.
int f = 1, i;
for(i = 1; i <= 5; i++){
f *= i;
System.out.println(f);
} [2012]
Ans. int f = 1, i = 1;
while(i <= 5){
f *= i;
System.out.println(f);
i++;
}
