assuming all reqd header files r declared, try this

void main( )
{
    int x[ ] = {10,20,30,40,50};
    int *p, **q, *t;
    p=x;
    t=x+1;
    q=&t;
    cout<<*p<<","<<**q<<","<<*t++<<","<<*(p+3);
}

output:

10,20,30,40

I thought of the same but wen i executed the program i got the output as

10,30,20,40

sugargal_anu

when there r many cout statements at one go(lik in this one) with increment operators, the line is executed from right to left, but printed from left to right.so the right answer is 10,30,20,40

sneha.bagri

oh!!!!!!!! i got it bcoz during d execution of cout statement d incerement (ie. post/pre) is done 4m right to left so value of **q will b ultimately 30

computer001

t++ is post inc so it shud come as 20 only...
but execution is from rite to left so new adress is tht of t++
so 30
so 10,30,20,40

sugargal_anu

try this

#include<iostream.h>
#include<conio.h>
void main()
{
    clrscr();
    for(int i=3;~i<0;i--)
    {
        for(int j=0;j<=i;j++)
            cout<<i+j;
        cout<<endl;
    }
}
