[c-prog] there's a bug in the program

[shahwalishaik]

Hello Friends,

 I've attended an interview few days back. The qeustion paper had
some programs. There's a bug in it, and we need to find it. Please,
help me find the bug.

   #include<string.h>
   #define MAX_STRING       80
   char  *Funct(char *p1, char *p2)
  {
    char str[MAX_STRING+1];
    int 1;

    str[MAX_STRING] = '\0';
    1=strlen(str);
    strncat(str,p2,MAX_STRING-1);
    return str;
}


[mod - There's more than one bug. Simply putting this code through a compiler 
would show you some syntax errors - you cannot use the numeral one as a 
variable name (the
    int 1;  and
    1=strlen(str);
lines. A runtime error is the potential buffer overrun in the call to strncat()
