hie...i have a easy..but don't seem to be working code

while (check == 0)
	{
		printf("\nEnter a character:\n");
		scanf("%c",&val);
		curr->next=initLLNode(val);
		curr=curr->next;
		printf("Do you still want to enter more characters\n1. YES\n2. NO\nChoose either 1 or 2:");
		scanf("%d",&chose);
		num=num+1;
		if (chose==2)
		{
			check = 1;
		}
	}

somehow the second time this thing is looping,
it does not stop and prompts me for "Enter a character"
it displays ("Do you still want to enter more characters\n1. YES\n2. NO\nChoose either 1 or 2:" and only stop to ask me to
choose yes or no there..

anyone can help?

The first call to scanf reads a single character, but you most likely had to hit return for the buffer to be sent for processing. Because of this, the stream contains two characters, the one you typed and a newline. The newline then causes problems with further calls to scanf. The simplest solution is to call getchar and clear it out before it can cause mischief.

while (check == 0)
	{
		printf("\nEnter a character:\n");
		scanf("%c",&val);
                getchar();
		curr->next=initLLNode(val);
		curr=curr->next;
		printf("Do you still want to enter more characters\n1. YES\n2. NO\nChoose either 1 or 2:");
		scanf("%d",&chose);
		num=num+1;
		if (chose==2)
		{
			check = 1;
		}
	}

well...i tried this
but it don't seem to work too..



confused:

while (check == 0)
	{
		printf("Enter a character:");
		val=getchar();
		curr->next=initLLNode(val);
		curr=curr->next;
		printf("\nDo you still want to enter more characters\n1. YES\n2. NO\nChoose either 1 or 2:");
		scanf("%d",&chose);
		num++;
		printf("\n");
		if (chose==2)
		{
			check = 1;
		}
	}

edna, try putting getchar() after scanf("%d",&chose);
