Thread: Input Buffer problem.

Okay, for example I have this code,

Code:

        char str[20];
        char chr;
        int num;        
         
        /* Case 1 */
        printf("\nNum: ");
        scanf("%d", &num);
        printf("\nStr: ");
        scanf("%s", str);
        
        printf("\nLetter: %d", str[0]);
        
        /* Case 2 */
        printf("\nNum: ");
        scanf("%d", &num);
        printf("\nChr: ");
        scanf("%c", &chr);

        printf("\nLetter: %d", chr);

And when I run the code,
On case 1: the str[0] has value of the first character of whatever you inputted.

On case 2: the chr has value of LineFeed (ASCII 10).

Now for my question,
Why on case 1 the str does not take the LineFeed character ?
Whereas on case 2, the chr takes the LineFeed character ?

Aren't both string and character supposed to take everything inputted into them?

I hope you get my meaning..

Thanks.

Hmm, I see, I didn't know that.

But anyway, thanks for your reply.
