4. switch

To execute a loop 10 times, which of the following is correct?

How many times will the following loop execute? Write the output of the code:

int x=10;
while(true) {
System.out.println(x++*2);
if(x%3==0)
break;
}

Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.

Example1:

Input: 1021

Output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4, NUMBER OF DIGITS = 4]

Example2:

Input: 125

Output: Not an SUPERSPY number [1+2+5 is not equal to 3]

Give the output of following code and mention how many times the loop will execute?

int i;
for(i=5; i> =l;i~)
{
if(i%2 ==1)
continue;
System.out.print(i+ ”
}

Give the output of the following program segment and also mention the number of times the loop is executed:

int a,b;
for (a=6, b=4; a< =24; a=a + 6)
{
if (a%b= =0)
break;
}
System, out .println(a);

Write the output:
charch= ‘F’;
int m= ch;
m=m+5;
System.out.println(m+ ” ” +ch);

Convert following do-while loop into for loop.
int i = 1;
int d = 5;
do {
d=d*2;
System.out.println(d);
i+ + ; } while (i< =5);

Analyze the given program segment and answer the following questions : 

for(int i = 3; i <= 4; i++){
    for(int j = 2; j <i; j++){
        System.out.print("");
    }
    System.out.println("WIN");
}

(i) How many times does the inner loop execute ?
(ii) Write the output of the program segment.

State the difference between while and do-while loop.

Convert the following while loop to the corresponding for loop: 

int m = 5, n = 10;
while (n >= 1)
{
System.out.println(m*n);
n--;
}

Analyze the given program segment and answer the following questions:

(i) Write the output of the program segment.
(ii) How many times does the body of the loop gets executed?

for (int m=5; m<=20;m+=5)
{   if(m%3==0)
   break;
else
if(m%5==0)
System.out.println(m);
continue;
}

Give the output of the following program segment and also mention how many times the loop is executed : 

int i; 
for (i = 5; i > 10; i++) 
System.out.println(i); 
System.out.println(i * 4);
