You are not considering carry forwarded.

try the case:

input
999
989

output
3

You are not considering carry forwarded.

try the case:

input
999
989

output
3

I have tried this case.
And I have found output 3.
So, again question what's the problem? I have changed my code as below. But no result:

Hi,

Just try this input.

5210357 1245874

Correct output is : 3 carry operations.

But your output is : 4 carry operations.

You have done some mistakes in carry operation.

ABDULLAH.

Any body plz tell me wheer is the error.
I don't find any error and i tryed all kind of I/O,but i got WA!


*************Code Removed***********

Try input '99 1'.

I try it and the answer is 2 carry operations.Its ok,then where is the problem?

Sorry that out put was ok in Turbo C but VC++ out put was wrong.
Pls cheack this one

********Code Removed***********

Check your code again. What is 'n'? And why are you using it? And 'long unsigned int' doesn't make any sense. To post codes you can use the 'code' option from the editor. And you can remove your unnecessary codes by editing posts.

Thanks Jan,at last i got AC,Can i Get ur email address?I'm in 3rd semister in RUET,(CSE).Some time i'll ask u for help bcoz this board take too much time.

thanks spykaj i got ac.

I've been trying so many times but i still got WA. Please help me to find the mistakes.

LZ why you take char when you can use long long int???

[quote="ranacse05"]LZ why you take char when you can use long long int???[/quote]

I'm just curious. Actually, i made another program using long but i still got WA. Here's the codes. Please check it if you're not busy. thx alot.

#include<cstdio>

int main()
{
long int a, b, input1, input2;
int ctr, jml=0, i;

while(a!=0||b!=0)
{
ctr=0;
scanf("%ld %ld", &a, &b);

input1=a;
input2=b;
for(i=0;i<10;i++)
{
jml = jml + input1%10 + input2%10;
input1/=10;
input2/=10;
if(jml>9)
{
ctr++;
jml = jml/10;
}
else jml=0;

if(input1==0&&input2==0)break;
}

if(ctr==0)printf("No carry operation.\n");
else if(ctr==1)printf("1 carry operation.\n");
else printf("%d carry operations.\n", ctr);

}

return 0;
}

OMG USE: !!!!!!!!!!!
