ICSE − Q & A

Can anyone pls tell me the diff. btw local variable and instance variable?

ALL THE BEST EVERYONE. DO WELL!

try this pattern- input - "bottle"           output-b o
                                                                     t  t
                                                                     l  e  -- for n terms

If we create 2 arrays :
arr1[]={1};
arr2[]={2};
and try arr1==arr2 , it will be false right? Because == checks reference and diff arrays have diff reference?

double d=Math.sin (x)
Where x is 1 radian
What will be the value of d?

GUYS THIS IS URGENT:
Cud u pls tell me if this code snippet is r8 for generating random no.s between 23 and 49?

while (count1!=5)
{
int num1=(int)(Math.random()*100);
if (num1<23||num1>49)
continue;
else
{
b[count1]=num1;
count1++;
}
}
Thanks a lot and all the best!

guys,all the best !!

Can some1 please give some tricky increment/decrement questions?

Is it wise to use string functions by converting number to string in number programme?

ar[]={1,2} arr[]={2,1}
Is ar[]==arr[]??
