Help with a small program!!
Hi ,
I am new to C programming and have a question on the following. I have to write a program which must accept a single character as input and echo that character before the enter key is pressed. The programming environment is GNU. The execution must end once ctrl D is pressed.I was not able to use getchar putchar to solve this. Can somebody help me out??

When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Thanks Hammer for ur post. I tried out the programs but they require the user to press the enter key before echoing the character. Can you please tell me how to go about this?

Well it helps if you actually READ what you're given. The first link tells you what you say you can't find.

From the second link:
The first link has a broken link at the end of the page, where it says "this FAQ entry".Code:#include <stdio.h> #include <termios.h> #include <unistd.h> int mygetch(void) { struct termios oldt, newt; int ch; tcgetattr( STDIN_FILENO, &oldt ); newt = oldt; newt.c_lflag &= ~( ICANON | ECHO ); tcsetattr( STDIN_FILENO, TCSANOW, &newt ); ch = getchar(); tcsetattr( STDIN_FILENO, TCSANOW, &oldt ); return ch; }

Here's a tip - post what you tried instead of whining "it doesn't work"
You may have to link to the library.I tries using curses.h but tht doesnt seem to work either!!
