a++;
System.out.print (a+ " : ");
}
Ans. int a,b;
a=2;
b=18;
while(a<=10)
{
a++;
System.out.print(a+" : " );
b=b-2;
}
10. Print the output of the program of question 9:
Ans. 3 : 4 : 5 : 6 : 7 : 8 : 9 : 10 : 11 :
11. Identify the errors in the following code and write the correct code:
for (int i = 1, i <= 10; i=i++)
{
System.out.print(i * i + " : ");
}
Ans. for (int i = 1; i <= 10; i++)
{ //[Explanation: 1 instead of, it will be;
st
System.out.print(i * i + " : ");
//2 instead of i=i++, it will be i++]

}
12. Convert from do-while to while loop:
int i=1, j=10;
do
{
i++;
System.out.println(i+2);
j--;
}while(i<j);
Ans. int i=1, j=10;
while(i<j)
{
i++;
System.out.println(i+2);
j--;
}
13. Convert to for loop and write the output:
int i=10;
do
{
System.out.println(Math.pow(i,2));
i--;
} while(i>=10);
Ans. for (int i=10; i>=10; i--)
{
System.out.println(Math.pow(i,2));
}
Output: 100.0
14. Convert to for loop:
int n=456, r;
while(n>0)
