My caesar output has no spaces

Question

I have little bug in my program with spaces; when the user writes "world, say hello" the output is correct but without spaces.

I tried to use:

if (isblank(n))
{
 text = n + ' ';
}

but that didn't help.

Answer 1

You don't necessarily have to use isblank() here. Instead, there should be an "else" case that executes when the "ith" character of the plain text to-be-encrypted is neither an uppercase nor lowercase letter. It should look something like this:

else
{
        printf("%c", plain[i]);
}

,assuming that plain is the name of the input string from the user that has to be encrypted by your programme.
