using getchar

[ankit banerjee]

I want to use getchar in a while loop such that it does not dont want to press enter everytime how is this possible
for eg
while((c=getchar())!='\n')
{
printf("%c",c);
}
i want this variable c to be printed each time i press a character in run time and not pressing enter at all how is this possible i dont want my output at the end but simultaneously with pressing the character the character should be printed

Your program does not have control until the user presses enter. Any number of characters may be entered but the buffer is not available to you until the user presses enter.

You would need to write your own keyboard driver. Or you could write in Windows code and look for message WM_KEYDOWN.

stdin is commonly line buffered. This means that characters are collected (buffered) in the device driver until a newline is typed (for stdin). It sounds like you want stdin to be unbuffered. Take a look at stdio.h function setbuf and setvbuf.
