Thread: please help.

hello guys. im in need of some urgent help over here. the case so far is like this:
the code below already checks if the user inputs a letter, it will be discarded. only numbers allowed.

now i need to enter another checking solution such as if (guess[0]>6)
in other words. i would like the invalid entry to pop up if a number aboe 6 is entered.

could someone please help me implement this into my code below. ive tried many solutions but all not working fine..

Code:

valid1 = 0;
while (!valid1) {	
	printf("ENTER GUESS 1: ");
	fflush (stdout);
	if (scanf("%d",&guess[0]) == 1)
	valid1 = 1;
	else
	printf("INVALID ENTRY, PLEASE TRY AGAIN\n\n");
	while (getchar() != '\n');
}

many thnx to anyone who helps.
greatly appreciated.

PS. sorry about the heading i was going to add more details but clicked on post too quickly.

Indenting properly is a good idea.

Code:

valid1 = 0;
while (!valid1) {	
	printf("ENTER GUESS 1: ");
	fflush (stdout);
	if (scanf("%d",&guess[0]) == 1)
		valid1 = 1;
	else
		printf("INVALID ENTRY, PLEASE TRY AGAIN\n\n");
	while (getchar() != '\n');
}

But how can it NOT work? What did you try?

You can use if/else if.
