C appending char to char*
- by Ostap Hnatyuk
So I'm trying to append a char to a char*.
For example I have char *word = " ";
I also have char ch = 'x';
I do append(word, ch); Using this method..
void append(char* s, char c)
{
int len = strlen(s);
s[len] = c;
s[len+1] = '\0';
}
It gives me a segmentation fault, and I understand why I suppose. Because s[len] is out of bounds. How do I make it so it works? I need to clear the char* a lot as well, if I were to use something like char word[500]; How would I clear that once it has some characters appended to it? Would the strlen of it always be 500? Thanks in advance.
