Thread: k&r ex1-18 removing trailing spaces.

ive been at this for a while. i just cant seem to get the logic down so if none of the below code makes sense or can be done a better way please suggest the way. =)

if this code is correct, how would i test to see if it actually removes trailing spaces.

Code:

#include<stdio.h>
#define MAXLINE 1000

int getline(char string[], int maxline);

main()
{
	int	c;
	int 	i;
	int	j;
	int	len;
	char	s[MAXLINE];
	
	for ( i = 0; i < MAXLINE - 1; ++i)     
		s[i] = c;
		
	len = getline(s, MAXLINE);
	j = len;
	--j;
	--j;
	while (j == ' ')    
		--j;

	s[j] == '\n';
	++j;
	s[j] == '\0';		
		
	printf("%s", s);
}

/*getline function returns len*/

int getline(char line[], int limit)
{
	int c, i;

	for (i = 0; i < limit-1 && (c = getchar()) != EOF && c != '\n'; ++i)
		line[i] = c;

	if (c = '\n') {
		line[i] = c;
		++i;
	}

	line[i] = '\0';
	return i;
}

thanks in advance for the response.
