    array out of bound seg fault

    Code:
    int read_word(int fld_delim, int rec_delim, int eor_delim, char field[MAXSIZE], FILE *fp) {
    
     int p, i;
            p = i = 0;
    
            while ( (p=getc(fp))!= EOF ) {
                   if( p == fld_delim) {
                          field[i++] = '\0';
                          return FLD_DELIM;
                   }
    
                   if( p == rec_delim) {
                          field[i++] = '\0';
                          return REC_DELIM;
                   }
                   if ( p == eor_delim ) {
                          field[i++] = '\0';
                          return EOR_DELIM;
                   }
    
                   if ( i <= MAXSIZE ){
                     printf("i=%d",i);
                          field[i++] = p; // <-- I get array out of bound here
                   printf("field= %s\n",field);
                   }
            }
            field[i++] = '\0';
            return FINISH;
    }
    Thanks for the help!

    So stop writing to memory you don't own. What more help do you want?

    An array is defined like so:
    int array[10];
    and is accessed:
    array[0] through to array[9]

    Accessing array[10] is going past the end, and is therefore out of bounds.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
