So you want to make a text editor, but you don't want to actually do the work?

[QUOTE]When a vector is declared to have a certain number of things such as you init it to size(10000) it's very inefficient to init it with a for loop[/QUOTE] When the vector is already resized, using a loop to initialize is no different from using a loop to initialize an …

[QUOTE]They don't bother teaching today's C/C++.[/QUOTE] That's not even today's C++. If they tried to teach today's C++, the teachers stuck in 1990 would have a stroke.

[QUOTE=sergent;1633922]Why almost always capital letters are used when defining macros or variables like [CODE]#define SOMETHING 432[/CODE] instead of [CODE]#define something 3243[/CODE][/quote] Macros are problematic in that they're a preprocessor effect.

[QUOTE]Then what it does?[/QUOTE] [ICODE]0<x<=2000[/ICODE] will be parsed as [ICODE](0 < x) <= 2000[/ICODE]. Or, depending on the value of x, either [ICODE]0 <= 2000[/ICODE] or [ICODE]1 <= 2000[/ICODE] since false and true evaluate to 0 and 1, respectively.

Try restarting b at 1 for every iteration of the outer loop. And instead of one loop counting to 5, consider using two loops: one counting up to 3 and one counting down from 2.

[QUOTE]compiled using Turbo c++ 3.0 compiler[/QUOTE] Have you considered dropping that ancient piece of shit and switching to a compiler that isn't twenty years old and severely limited under modern architectures?

[QUOTE]This program is written in C++ not C.[/QUOTE] At a glance, I'd call that code C, and bet that it compiles just fine as C. It would also compile as C++, but if you're using a strict C-compatible subset of C++, quibbling over the code being C++ is kind of …

The standard library equivalent can be found in the <time.h> header (or <ctime> for C++). But being used to Java's Date and Calendar classes, you'll probably find the interface either quaint or woefully inadequate. p.s. I fairly recently posted a [URL="http://www.daniweb.com/software-development/cpp/code/335271"]code snippet[/URL] for for the beginnings of a date_time class …

[QUOTE=pseudorandom21;1633474]Do I Need to know assembly?[/QUOTE] While I'm an advocate of learning assembly, you don't need to know assembly to write a Windows driver. You might choose to use assembly at some point, in which case knowing it expands your options, but it's not a prerequisite.

Well, obviously strstr() alone won't do the job since it performs an unconditional exact match. You'll need to customize the behavior a little bit to suit your definition of a word: [code] #include <ctype.h> #include <stdbool.h> #include <stdio.h> #include <string.h> bool is_word(int ch) { return !isspace((unsigned char)ch) && ch != …

In anticipation of questions like this, I wrote a [URL="http://eternallyconfuzzled.com/tuts/datastructures/jsw_tut_linklist.aspx"]tutorial[/URL] on linked lists. The code is in C, but the concepts apply for any language.

Um, 20 bytes is well beyond the range of C++'s built-in types. I suspect you want an arbitrary length math library like [URL="http://gmplib.org/"]GMP[/URL].

You have multiple problems with that code. Since I'm so nice, you can compare and contrast with the "corrected" code: [code] #include <ctype.h> #include <stdio.h> unsigned int get_int() { unsigned int c, sign; while (isspace(c = getc(stdin))) ; if(!isdigit(c) && c != EOF && c != '+' && c != …

[URL="http://www.boost.org/doc/libs/1_47_0/doc/html/boost_random.html"]Boost.Random[/URL] would be a good start. Just because rand() doesn't work for you doesn't mean you should write your own version that's better (you'd likely end up with something worse). There are many existing random number generators out there. [QUOTE]i have tried using rand() but i dont like it because …

[QUOTE][CODE]scanf("%lf",a);[/CODE][/QUOTE] You're missing the address-of operator: [code] scanf("%lf", &a); [/code]

clrscr() is a non-standard function typically declared in the <conio.h> header. Provided your compiler supports both <conio.h> [i]and[/i] clrscr(), including that header will fix your error. However, since your use of clrscr() is nonsensical anyway, my recommendation would be to remove it entirely (and change getch() to getchar()). In fact, …

I haven't had any problems with my iPad, though this sounds like a browser issue. Do you have any alternative browser applications? I'm not familiar with the Galaxy Tab.

How did you clear the stringstream? Can you post a more complete example?

[URL="http://eternallyconfuzzled.com/tuts/algorithms/jsw_tut_sorting.aspx"]This[/URL] is a tutorial I wrote about sorting in C. It can easily be translated into C++, especially since you're using a a very C-centric subset of C++. Check out the insertion sort and merge sort sections for examples dealing with linked lists.

[B]Last Activity: Nov 26th, 2007[/B] The OP doesn't need help anymore.

The error is precisely as stated. The system() function expects an argument of type const char*, and std::string doesn't have an implicit conversion to that type. You need to call the c_str() member function: [code] system(drvPath.c_str()); [/code]

[QUOTE]What is the significance of the letter n or l in these names?[/QUOTE] The "n" means that the operation is bound by a character limit, with the limit being remaining available space in the destination (in the case of strncpy() and strncat()), or a partial string count (in the case …

It's a scanset. scanf() will look for characters between the brackets. A leading ^ acts as an exclusion modifier, so [ICODE]%[^\n][/ICODE] will look for anything that's not a newline and stop reading when it encounters a newline.

[QUOTE]However, the goto statement is still executed[/QUOTE] The goto statement didn't execute. It only seems that way because your labeled statement is in both execution paths. Consider this: [code] #include <stdio.h> int main() { int a; a = 1+1; /* if (a!=2) { goto error; } */ error: printf("error is …

It works exactly as it should. You're passing month by value, so within renameMonths() "january" is being assigned to a copy. The original object in main() remains the same. To change the original object, you need to pass a reference (or a pointer): [code] void renameMonths(string& month) { if (month …

[QUOTE=hqt;1628555]but I don't know the different purpose of two type of declare: with above example is: [code] struct node** lastPtrRef=*Head;//type 1 struct node** lasPtrRef=&Head; //type 2 [/code] [/QUOTE] This is what I think your question boils down to, and the answer is that the first declaration is wrong while the …

[QUOTE]Is there a way(builtin library functions,methods..etc.) to find the number of digits in the integer?[/QUOTE] Nope, you have to write that yourself. Though you can certainly use standard library functions to make it easier (log10() for example).

How do you do it on paper? The parts where you find yourself repeating the same task will fall into a loop in code.

[QUOTE]error C2065: 'x' : undeclared identifier Simple as that. [/QUOTE] Yes, quite simple. You try to use x in printing() (via the USER_NAME macro), but x isn't declared in printing(). Macros are usable from the point of definition down (unless you #undef) and not bound by scope, so the effect …

[QUOTE]I tried using libs but some of them seemed to do all the work for me, the others seemed to be too complicated.[/QUOTE] How about writing your own version of those libraries? You might realize why doing all of the work for the programmer is a good thing, and/or why …

Okay, 'd' instead of 'the' I can understand (I don't agree with it, but I can understand), but WTF is up with omitting 'ee' from "between"? There's a point where being lazy and being a retard come together, and it's generally best to stay away from it when trying to …

It's a character constant with multiple non-escape characters (ie. 'ab').

[QUOTE]It does redirect but only from my main function.[/QUOTE] Is this other function coming from a DLL or something? Your described behavior suggests that the two functions are using different instances of stdout, or foo() is using some other method to write to standard output.

The difference is subtle, but significant: [code] char cards1[] = "JQK"; // Array initialized with the contents of a string literal char* cards2 = "JQK"; // Pointer to a string literal object [/code] In cards1, you own the object, it's modifiable, and everything is hunky dory. In cards2, you own …

Your object is not a pointer, so there's no need to use the arrow operator. Also, the [] operator is already dereferencing your pointer, so there's no need for an explicit dereference either: [code] class myclass { public: int *ptrarray; myclass() { ptrarray = new int[2]; ptrarray[0] = 5; ptrarray[1] …

[QUOTE]if this system was expanded into a distributed environment the main issue I can for see is with so many people using the system then posts will go out off order[/QUOTE] Can you provide an example of this case? [QUOTE]so that only one user can have access to posting on …

Well, since your first example is an prime example if dereferencing an uninitialized pointer, I'm tempted to suggest that you learn more about pointers. But I actually have a better answer to your immediate problem of not knowing when to use a pointer: don't use pointers. If you refrain from …

First, beggers can't be choosers. You're not likely to end up doing what you're really interested in with an entry level job. The point of an entry level job is getting some practical experience, not landing your dream job. ;) Even if you want to do back-end stuff, it's smarter …

02h is a control character, not the numeric value of '2'. What you're looking for is 32h.

[QUOTE][CODE]s2[i]=s2[i]+s1[i];[/CODE][/QUOTE] What makes you think s2 is large enough to be indexed with s2[i]?

It's working as expected. The next character is '\n', so the loop terminates immediately. You never end your string with a '\0' character, and the program prints garbage.
