Thread: need some help

1.)

Code:

int x = 729799756911412043;

Is it really capable of holding such a large value?

2.)

Code:

scanf("%d",&c);
c = getc(stdin);

Why are you reading twice from the stdin?

Code:

fflush(stdin);
c = getc(stdin);

should do.

3.) c1 has never been initialised, and you are printing it's value. It's not an error (unless you use it somewhere), but just a point.

4.) Place the code between tags: [ CODE] and [/CODE] and not [CODE/]

5.) What is the error you are getting, be a little more descriptive.

>what i am tring to do is if you get the correct numeric value ...
Then:

Code:

fflush(stdin);
scanf("%d",&c);

alone should do.

>Then:
>fflush(stdin);
>scanf("%d",&c);
>alone should do.
I sure hope not, using fflush on input streams may cause demons to fly out your nose. Since this is an unpleasant experience, you should avoid undefined behavior. To remove the trailing newline from scanf you can use any number of fixes, the most effective and general that I've found is:

while ( getchar() != '\n' );

But something as simple as:

scanf("%d",&c), getchar();

Will work as long as there is only one character left in the stream.

As for the original problem, a better description of what the desired input/output combinations should be as well as what the program isn't doing correctly is usually more helpful.
