Usually in a char[] array in C, the last character will be "/" ?

char  sz[7];
sscanf(line, "level %s",  &sz[]);
for (int i = 0; sz[i] == "/"; i++)
{
if (sz[i] == ":")
continue;
.....
.....
}

sz[] will be getting value in the format 120:0
So can I use the above to trace through sz[] array from beginning till the end?
If its wrong please guide me the correct way.
Thanks.

Hi gopikrish,

The normal way to walk a string looks something like:

for ( i = 0; s[i] != '\0'; i++ )

Although some shorten it to:

for ( i = 0; s[i]; i++ )

which I personally dont like but is acceptable.

Why do you thing that there is a "\" at te end of a string?

No, Usually in a char[] array in C, the last character will be '\0' (null character) not "/"

characters are enclosed in '' not in "".

i dont know what you are trying to achieve but it should be

char  sz[7];
sscanf(line, "level %s",  &sz[]);
for (int i = 0; sz[i] != '\0'; i++)
{
if (sz[i] == ':')
continue;
.....
.....
}

the last character of a C-array according to C99 standards should be '\0', there is no way it could be '/'

so what you have to do is this

char  sz[7];
sscanf(line, "level %s",  &sz[]);
for (int i = 0; sz[i] != '\0'; i++) // or for (int i = 0; sz[i]; i++)
{
if (sz[i] == ":")
continue;
.....
.....
}
