problem with pset 2 initials (more confortable)

Question

im having a problem with initials (More Confortable) in Pset2. The ckeck50 software outputs this:

: ( outputs "MB" for " milo banana "
\ expected output, but not "MB\u0000\n"

But when i try to run my program with that input i see no problem...

Thanks for your time!!

Here is my code

#include <stdio.h>
#include <cs50.h>
#include <ctype.h>
#include <string.h>

int main (void)
{

    int i;
    int j;

    string name = get_string();

    for (i = 0; i <= strlen(name); i++)
    {
        if(name[i] == ' ')
        {
            for(j = i; name[j] == ' '; j++);
            putchar(toupper(name[j]));
            i = j;
        }
        else if (i == 0) 
            putchar(toupper(name[i]));
    }
    putchar('\n');
}

And here is the check50 output:

~/workspace/pset2/initials/ $ check50 2016.initials.more initials.c
:) initials.c exists
:) initials.c compiles
:) outputs "MB" for "Milo Banana"
:) outputs "MB" for "milo banana"
:( outputs "MB" for " milo  banana "
   \ expected output, but not "MB\u0000\n"
:( outputs "MB" for "  milo banana  "
   \ expected output, but not "MB\u0000\n"
:) outputs "RTB" for "   robert   thomas bowden"
:) outputs "RTB" for "Robert Thomas Bowden"
:) outputs "R" for "ROB"
:) outputs "RTB" for "Robert thomas Bowden"

Thanks a lot!

I solved my problem. In some cases i was printing the \0 character at the end of the string. The new code, is this

#include <stdio.h>
#include <cs50.h>
#include <ctype.h>
#include <string.h>

int main (void)
{

    int i;
    int j;

    string name = get_string();

    for (i = 0; i <= strlen(name); i++)
    {
        if(name[i] == ' ')
        {
            for(j = i; name[j] == ' '; j++);
            if (j < strlen(name))
                putchar(toupper(name[j]));
            i = j;
        }
        else if (i == 0) 
            putchar(toupper(name[i]));
    }
    putchar('\n');
}
