macOS fgets Isn't Waiting For Me

[Halfmaster1]

I am using the fgets

char extraString[20];
		
		i=0;
		while (i!=20) 
		{
			extraString[i]=0;
			i++;
		}
		i=0;
		
		fgets(extraString, 20, stdin);

Bu the program skips right over it, going on the the rest of the code, even thought I haven't typed a single letter.

Thanks

Can you post a full compilable example?

Can you show us what's stored in extraString?

Does this happen the very first time you try fgets, or only subsequent attempts?

What is the return code from fgets? How is the application being launched?
eg: If you're launching it on a console, then STDIN should be a valid input stream. Some other launch mechanism may not have a valid input stream, and thus result in EOF for any call against STDIN.


Also.. you might want to look at memset to clear your extraString variable.

memset (extraString, 0, 20);

Sorry for taking so long, I had things to do.

That is an exact copy paste from my code. I later add the values of the chars, and use that number elsewhere in the program, to allow the user to control the outcome, with a word, that is easier to remember.

Oh, and thanks for the memset function, I'll use it in the future.

Thanks. (<--should make that my signature)


Edit: It started working again. Don't know why, I didn't change anything.
