Thanks, Corona and Don.
Don, while i was reading ur reply to figure out my mistake, i realize tat i<100 was juz a typo, i wanted to set it i<10. Btw, thanks for tis new lesson
I wont quit programming, i feel it is fun to solve problem.
Corona, so i hav check out tis ASCII character set, yea i found tat 1st 16 character of ASCII character r non printable control characters. I wonder if 0 = 0, 1 = 1, 2 =2 and so forth, and '0' = 48, why will it bcome 1 when we minus '1' - '0' and not a non printable control characters? If we add '0' to 1, will it bcome bak '1' or as u said '0' = 48 and bcome 49?? How do dey differentiate it is a character set or an integer??
Sorry everyone who r trying to reply me. I feel tat im annoying, i hope tat u all don mind to answer my question

Hi,
I would like to read an input from keyboard using getchar. However, if no input (No Carriage return/new line none whatsoever) is given after say, 5 seconds, I would like to skip the getchar and move on. How do I do this in C. I'm using GNU compiler set.

Hi,
What happens to process state when getchar() is called? I wrote a C code in which I call getchar() somewhere down the road. I forgot about that, I started the process, put it in bg and disowned it using "disown". Now, how do I see where that process has gone/how do kill it?

getc
GETC(3S) GETC(3S) NAME
getc, getchar, fgetc, getw - get character or word from stream SYNOPSIS
#include <stdio.h> int getc(stream) FILE *stream; int getchar() int fgetc(stream) FILE *stream; int getw(stream) FILE *stream; DESCRIPTION
Getc returns the next character from the named input stream. Getchar() is identical to getc(stdin). Fgetc behaves like getc, but is a genuine function, not a macro; it may be used to save object text. Getw returns the next word from the named input stream. It returns the constant EOF upon end of file or error, but since that is a good integer value, feof and ferror(3) should be used to check the success of getw. Getw assumes no special alignment in the file. SEE ALSO
fopen(3), putc(3), gets(3), scanf(3), fread(3), ungetc(3) DIAGNOSTICS
These functions return the integer constant EOF at end of file or upon read error. A stop with message, `Reading bad file', means an attempt has been made to read from a stream that has not been opened for reading by fopen. BUGS
The end-of-file return from getchar is incompatible with that in UNIX editions 1-6. Because it is implemented as a macro, getc treats a stream argument with side effects incorrectly. In particular, `getc(*f++);' doesn't work sensibly. GETC(3S)
