    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.
    #define MAXLINE 1000
    int getline(char string[], int maxline);
    	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;
    	while (j == ' ')    
    	s[j] == '\n';
    	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;
    	line[i] = '\0';
    	return i;
    thanks in advance for the response.

    char test[] "does this work?       ";
    function( test );
    printf("\'%s\'", test );
    That's how you test it. Simply surround the would-be-output by quotes, or put some other item past what would be the end, and see if it ends up displaying correctly.

    Hope is the first step on the road to disappointment.
