I'm a beginner to C, so please try not to laugh at the following question...
I am writing a short program that asks the user to input a string, then a small function manipulates the string. It then loops back to scanf, waiting for more user input. I understand how to end the loop if the user enters a particular string, but I want to end it when the user enters ctrl+d without having to press enter. What am I missing? Thanks.
Add an If statement kinda like this i would assume.
if (strstr(argument, 'whatever the value for cntrl-d is')
{
exit(1);
}
I think, i'm a novice to, but thats where i'd start.
To error is human, to really foul things up requires a computer
Thanks for the response, Twiggy. However, if I'm not mistaken, I think that solution would require the user to hit enter to terminate the string, which, unfortunately, is not an option. I want the program to end immediately if the user hits ctrl+d and not wait for the user to hit enter.
I'm a bit unsure, but...Of course, this all rests on setbuf (stdin, NULL). If it doesn't work, then you'll have to look into the compiler dependent BIOS functions for your compiler.Code:char string [100]; setbuf (stdin, NULL); for (;;) { for (i = 0, c = getchar(); c != CTRL_D && c != '\n'; c = getchar()) { string[i++] = c; } if (c == CTRL_D) break; string[i] = '\0'; doStringStuff(string); }
Callou collei we'll code the way
Of prime numbers and pings!
