| | >I'm reading directly from the disk, so I guess I have to use ReadFile(); Why? What does `ReadFile()` do that any other read technique doesn't do? To alleviate your real problem, make your buffer larger than 512 -- say 16 more. Always read into the last 512 of that buffer, … |
 | 1st: Store the password in a file. Read it in for the compare. 2nd: For more security, encrypt the password somehow. Decrypt it before comparing.  |
| | Yes, ASM can be very useful. If you need to rewrite a function because its too slow, ASM can make it quite a bit faster. If you need to interface with a module of some kind and C++ is too clumsy to do the interface, ASM to the rescue. Drivers …  |

 | That's assuming a selection structure means a switch statement. Since we don't know the context of your terms, it's hard to say with accuracy. |
| | The closest is a character array: char *name = "Jody"; // create a pointer pointing to the name of 5 chars char name2[] = "Mary"; // create an array of 5 chars to hold the name char name3[20]= "Janine"; // create an array of 20 chars to hold the name … |
| | Re: Decimal > the thing I am confused is already been corrected but then I am stuck as I have no clue how to continue coding? And this is supposed to give us the information we need to help you? Think about actually asking a question we can answer. |
 | > for (i = srclen, j = 0; i < srclen && j < dstlen; i++, j++) If **i** starts as **srclen** when will `i < srclen` be true? What happens to your loop in this case? IMO, you need one more index value. Since you have **srclen** and **dstlen** …  |
| | I don't see anything wrong with any *line 18*. When asking for help, you need to give details. What is the problem you see? You gave us a line, but is it the same line in the post? If not, use the numbers in the post. |
| | Can't read the code because of lack of [formatting](http://www.gidnetwork.com/b-38.html). Try again.  |
| | First: Learn to [format](http://www.gidnetwork.com/b-38.html) your code consitently. It's difficult to follow. Second: [feof()](http://www.gidnetwork.com/b-58.html) is used incorrectly. Third: [system("pause")](http://www.gidnetwork.com/b-43.html) is not a good way to pause a program. Last: [scanf("%s",&text);](http://www.gidnetwork.com/b-62.html) is dangerous. `fgets()` is much safer. Since you didn't explain what you are trying to do beyond reading and writing the … |
| | Re: GDI PNG >I looked up the format but it looks nothing like a bitmap... Why should it look like a bitmap? It's a PNG format. >... and I read the GDI doesn't support PNG's. So how does LibPNG do it then? By not using GDI I suppose. Since it's called *LibPNG*, it … |

| | Re: Pointer question > `#define FOR(i,a,b) for(int i=a;i<b;i++)` Why? What's wrong with just using the `for` statement? Making it a define simply makes the program confusing. |

| | Re: Error in Output Look up again how to use a character array as a **string**. You are missing a couple key pieces of information about a string's length and termination character.  |

 | > Also don't use #include <conio.h> and getch() because they are really really bad. Read *bad* as non-standard and prone to cause problems for you when you start using one of the 99% of the compilers that don't know what `<conio.h>` and `getch()` are. The standard definition of *bad* doesn't … |

| | Problem #1: Never **ever** put code or variable definitions in a header file. Header files are used to *declare* functions and variables, not *define* them. Problem #2: void showList(const int list[], const int n) { cout<<"The list is ..... " <<endl; for (int i=0; i<n; i++) { cout<<setw(8)<<right<<list[i]; if ((i+1)%1000==0) … |
| | Re: char ** It's a *pointer* that points to a *pointer* that points to a *char* As for how it works, work it out. Draw a map of memory and see how it could possibly be layed out and used.  |

| | Re: sorting > Write the pseudocode to find the record with a specific studentID Well, do what the instructions say. If you have a list of numbers, how would **you** find a specific number? Assume each number is on 1 index card in a file box. Write down each step (the psuedocode) … |
 | Only [B]Ancient Dragon[/B] has the correct answer. You cannot ++ or -- the same variable in the same statement. The C Standard says doing so is undefined and not guaranteed to give the answer you expect.

 | Code Snippets should not use anything in `conio.h`. They should be written so anyone can comple the program. |
| | >A much simpler way, if this concatenation is just part of a much bigger program, is to use atoi and itoa. itoa() the two numbers, then strcat(), then atoi() back. **atoi()** is simpler than (x1\*10) + x2? How do you figure that? Please explain... And [itoa()](http://www.cplusplus.com/reference/clibrary/cstdlib/itoa/) is not generally available …  |
| | To make your code more readable, look at how **pyTony** wrote the subscripte value. I'm all for using SPACEs, but too many also make code hard to read. |
