As the ICSE exam is over, we can talk something about the questions that came there in Comp. Appl. paper. There was a mixed response from the students regarding this year's question paper. If you want to share your views you feel free to do so.

I wish all ICSE examinees the very best for tomorrows Computer Application test.

//Pascal's Triangle- the mathematical way
class Pascal
{
double fact(double n)
{

return (n > 1) ? n * fact(n - 1) : 1;

}
double ncr(int n, int r)
{

return fact(n) / (fact(r) * fact(n - r));

}
void generate()
{
for (int i = 0; i < 15; i++)
{
for (int j = 0; j <= i; j++)
{
System.out.print((int)ncr(i, j));
}
System.out.println(" ");

//Fibonacci Recursive Way:

class RecFibo
{
void series(int term)
{
for(int i=1; i<=term;i++)
{
System.out.println(fibo(i));
}
}
double fibo(int n)
{
if(n<=2.0)
return 1.0;
else
return fibo(n-1)+fibo(n-2);
}
}

//If you don't want very long series, you may change double to int and put the '.0' off from the rear side of the numbers.

Fibonacci Series Ordinary Way:

public class Fibo
{
public void display(int term)
{
int t1=0,t2=1,t=t1+t2;
for(int i=1;i<=term;i++)
{
System.out.print(t+" ");
t=t1+t2;
t1=t2;
t2=t;
}
}
}

Q.Enter a year and test whether it is a leap year or not, shorter way.....

Ans.

public class LeapYearAnother
{
public boolean isLeapYear(int year)
{
return((year%4==0) && (year%100!=0) || (year%400==0))?true:false;
}
}

Q. Input a year in the method call box as argument and get the result from method return dialog box. true means the entered year is a leapyear, otherwise not.
Ans.

public class LeapYear
{
public boolean isLeapYear(int year)
{

if (year < 0) {
return false;
}
if (year % 400 == 0) {
return true;
} else if (year % 100 == 0) {
return false;
} else if (year % 4 == 0) {
return true;
} else {
return false;
}
}
