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.

Code:

---

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.

Quzah.
