Function Problem

Code:

---

void passgets(char pword[],int maxlength){
    int counter=0;
    char ch;
    while((ch = getch())!='\r'&&counter<maxlength-1){
                                                      if(ch =='\b'&&counter>0){
                                                                              printf("\b \b");
                                                                              counter--;
                                                      }
                                                      else{
                                                          pword[counter++]=ch;
                                                          putchar('*');
                                                      }
    }
}

I have put that together from combining code from a few of the previous threads about masking passwords. The problem is that when I test it it ends up with a bunch of random characters at the end. How do I fix this?

Null terminate the string.

You need to append the \0 yourself.

OK I tried adding

Code:

---

strcat(pword,'\0');

---

to the end of the function but then once it hits that the progam crashes. How else should I do it?
~Sven

pword[counter] = '\0';
Easy innit?

Code:

---

strcat(pword,'\0');

---

1) strcat needs the first to be null terminated in the first place
2) It expects a null terminated character pointer as the second

Thanks Salem I wasn't thinking that it was that simple.
