hello to all...
i m new to linux and i m trying to run c program in c so problem is i cant include header file #include<conio.h> and its related function.....

pls help me out..

Hello lonely,

first of all the description of your problem is not very good so its quite hard to give you any pointers. Also please use some punctuations. Makes it easier to read.

My guess is you are trying to compile c code?

if the compiler can't find the included libraries i guess they are not installed or are in the wrong directory. Try to find the include file with

find / -iname "conio.h"

It should give you the full path to the file. If not, it's not installed.
Else copy it to the directory where you are compiling and change the line

#include <conio.h>

to

#include "conio.h"

This tells the compiler to look in the working directory and not in the include pathes.

If you need any further help after describing your problem a bit more I'm glad to help you out.

[trainee@localhost progc]$ find /iname "conio.h"
find: /iname: No such file or directory
find: conio.h: No such file or directory

above is error

this is my program

#include<stdio.h>
#include "conio.h"

int main(void)
{
clrscr();
char str[20];
printf("enter your string");
gets(str);
printf("entered string is %s",str);
return 0;
}

conio.h is declares functions for MS-DOS I think. Not sure if you will find that on any Linux distribution.

I guess you need it for clrscr() - try replacing that with:

What happens if I type in a string that's 100 characters long?

thanks....

Linux Distro's do include software compatibility with M$-DOS programs and terminal windows. They are not in every Distro, YOU will need to hunt around; or better yet, install the software to run the programs correctly.

If i am not mistaken the function 'gets' is depreciated and shouldn't be used. Try using scanf.

Not sure if it's depreciated, but it's a security risk (buffer overflow) as a user can enter more characters than the size of the buffer (in the above example it's 19 plus a terminating NULL).

I think that scanf suffers from the same problem (correct me if I'm wrong).
I always use fgets.

PS there is a dedicated programming forum at LQ.

iirc, although you may be able to find conio.h in an MS-DOS virtual env, it's not supported under native Linux (Unix doesn't assume the keybd in the same way) ... I could be wrong ...
