>>CWinsockInterface::~CWinsockInterface Sounds like something that you wrote. To my knowledge there is no such Microsoft class.

1) yes -- see [URL="http://www.cplusplus.com/reference/clibrary/cstdlib/atexit.html"]ateixt()[/URL] 2) probably not. 3) No. MS-DOS had terminate-and-stay-resident programs that did something like that.

[QUOTE=jephthah;572887]okay, experts, i need help.[/quote] :icon_eek: I think the problem is the way you are opening the file. [quote] [b]a+[/b] Open a file for reading and appending.

c++ has other more dependable typecasting. C-style typecasting can let you kill yourself if you don't know exactly what you are doing, such as in this example attempting to typecast to normally incompatible data types. [code] double a = 12.34; char* b = (char *)&a; int c = (int)b; [/code] …

looks ok to me, except in the cin.getline() lines you should use sizeof instead of hardcoding the number [icode]cin.getline (text1, sizeof( text1 ) );[/icode] And you could declare a const int to define 256 instead of hardcoding it everywhere.

Where is function [b]getline()[/b]. It isn't a standard C function so you must have written it yourself. I thought you are supposed to write the new text entered from the keyboard into the file? Your program isn't doing that. And you need to rewind the file pointer back to the …

1) why use double in the struct since the values in the file are only integers. 2) A linked list would be a better choice because it is easier to add new structs. [URL="http://richardbowles.tripod.com/cpp/linklist/linklist.htm"]Here [/URL]is one of the many tutorials you can find with googler.

never ever for any reason use gets(). [URL="http://www.gidnetwork.com/b-56.html"]Here's why[/URL]. >>Could it have something to do with using gets()? Yes. [b]instr[/b] can only hold 9 characters plus the null terminator and you are trying to stuff more than that into it. gets() is scribbling the overflow all over your program's memory.

>>but my inner loop for j is working again and agian instead of just working for 3 times. are you talking about function addBlackBook() ? Of course it does because you told it ro run that j loop 500 times (line 56)!

In ComplexNumber::ComplexNumber you are supposed to set the values of the class variables to that of the parameters.

line 35: you need to pass variable grade by reference to that Get_Letter_Grade() can change its value. Then in main() you need to save all the graded in an array so that the GPA can be calculated. line 39: the value of [b]number[/b] is never set to anything so all …

Very humerous and very very true. I saw a lot of drunks like that when I tended bar 30 years ago.

The loop at lines 28-32 could be better written like this: [code] int i = 0; while( i < arraysize && infile >> numbers[i] ) { i++; } [/code] line 34: do you know for a fact that the file contains exactly 8 integers? It would be better to pass …

you have to put the timer code in a second thread then when someone types something in thread1 kill the timer thread. How to construct new threads depends on the operating system.

If the data contains random-length records or lines then you have no other choice but to use sequential access. As always, there are a few exceptions, such as if you create an index file that contains the offsets to the beginning of each line or record, but probably goes beyond …

Functions writtein in C language can be called by almost every other language.

First figure out how to split the string then worry about how to write the overload operator. What kind of string -- character array or std::string? How are you supposed to know where to split the string? Is there something in the string that is supposed to tell you where …

why did you put a return in the middle of main() ? Lines 12-19 will never get executed because of that unconditional return on line 11. Just delete line 11 and the reset will be executed.

From the error number I'd say you are using one of the Microsoft compilers. If that is true you can easily and quickly find out the missing { or } by putting the cursor on one of the brackets and hitting Ctrl+{ or Ctrl+}. This doesn't work so well if …

Or you could use std::string's at() method, but I don't see that very often.[URL="Error: c-project_.c(7,2):Unable to open include file 'stdbool.h"] Read this about it[/URL].

line 32 sets status to something other than 10. That means its value is not 10 when line 40 is executed, so the loop continues. I would use a different variable, such as [icode]bool found = false[/icode] then set it to true when line 30 is executed. [code] bool found …
