Thread: Simple Gets() problem

Take all user input as a string. If you need to convert to a number, attempt to convert to a number.




Lather, rinse, repeat.

here's how I use fgets:

Code:

#include <stdio.h>
#include <string.h>

char *strget (char *str, int size, FILE *ip)
{
	char *pointer;
	int clear;
	char *ret;

	ret = fgets (str, size, ip);

	if ((pointer = strchr(str, '\n')) != NULL)	/*if newline is present*/
		*pointer = '\0';			/*change it to \0*/

	/*otherwise there is at least one character in the buffer, so flush it*/
	else while ((clear = getchar ()) != '\n' && (clear != EOF));

	return ret; /*return fgets's return value just in case*/
}

The above code was written for C, hence the headers and stuff.
What it does is uses fgets to read in a string, removes the
newline if necessary and flushes the buffer if necessary -
everyone should have a function like this IMO. You can use it in
main just like fgets as normal, but it cleans up after itself. Then
do as Dave_Sinkula and citizen have said.
