ops... i finally finished it, i've changed the code into
while ((cin >> v >> t) != 0)
{
blablabla
}
although i still dont get what does the while statement mean.. heuheuheuhue

I would simply do
Some explainations here:
When cin fails to send values to v (or t), it returns an empty stream.

yes i do agree that the word constant is important.
i initially thought that this was a calculus problem and that integration is needed to find the distance-time function...

Code: Select all
#include <stdio.h>
int main(int argc, char **argv)
{
int v1,t1,v2,t2;
scanf("%d %d",&v1,&t1);
printf("%d\n",2*v1*t1);
scanf("%d %d",&v2,&t2);
printf("%d",2*v2*t2);
return 0;
}
Why's that wrong ?
I don't believe it....
It specifies the 2 inputs are integers,
and so it is......
Why..................................................

Hi,
I come from the same University and department as you but I am little bit older. Go back to the course homepage to read the example of 10055(AC code, input and output) provided by your tutor. You will know why you WA.

Vala, the problem is you are assuming that there will be exactly two test case, in reality there will be many more case and you should read until EOF.
Code: Select all
while ( scanf("%d %d",&v1,&t1) == 2 )
{
printf("%d\n",2*v1*t1);
}

I should suggest other people not reply this thread anymore in my last reply, but I forget.
As Vala is doing his homework, and him tutor is already providing enough and easy-reading info to him, he should get the answer himself.

#include <iostream.h>
void main ()
{int a,b ;
while(scanf("%d %d", &a ,&b)==2)
{

cout << 2*a*b<<endl;
}
}
but is w.a. i don't understand

Hi, Q10071 asks for outputs of "displacement", instead of "distance".
The former is vector(signed), the latter is scalar(unsigned).
I/O
