[URL="http://curl.haxx.se/"]cUR[/URL]L is the library which is used to do HTTP/FTP and similar protocols. There is a decent binding [URL="http://curl.netmirror.org/libcurl/cplusplus/"]cURLpp[/URL] for C++ which would be best for what you want. PS: C++ language as such do not have such functionality.

One suggestion would be to build a html parsing program and then perhaps connect to [url]http://primes.utm.edu/lists/small/10000.txt[/url] and read out the list of primes into the memory and write them down to a file. Or you could choose[URL="http://www.numberempire.com/primenumbers.php"] this[/URL] website but the you'll need HTTP/POST feature to get the prime. PS: …

Well, the therad is burnt now. The solution has been pointed by s.o.s ( sorry I am not putting those tildes). Tylor Theorm will come handy to you for all this 'magical' function. you could even calculate sin,cos,tan, etc etc. But this is not the correct way to learn programming. …

I agree with Hemsworth. C++ is a programming language. You project do not require any programming backbone. You should also use a similar animation suite. If Adobe Flash is not affordable, you might look at Open Flash [url]http://www.osflash.org/[/url] Also, have a look at [url]http://www.openlaszlo.org/[/url] It is not good to use …

If everyone is giving opinions, I would also cast my vote to GNU GCC If you are on a Linux, you probably already know about it. GNU g++ is the command line compiler. But there exists various IDE like Dev-C++ which uses GNU g++ as the compiler. I personally use …

>>Then you can use stricmp() stricmp is not a standard function.

Yes. Input the date as a std::string . Then use the[URL="http://www.cplusplus.com/reference/string/string/substr/"] substr[/URL] function to slice the string to get individual strings for Date, Month and year. Lastly you would want to convert the std::string to integer, Use stringstream to convert the string into the integer(refer [url]http://www.parashift.com/c++-faq-lite/misc-technical-issues.html#faq-39.2[/url])

You may use third party library like libcURL([url]http://curl.haxx.se/libcurl/[/url]) which works well in fetching such webpage as strings. If you problem is solved, please mark the thread as solved so that others don't waste time on this problem.

int is a very poor choice for a data representation of Date. The right thing would certainly be to accept the user input as string -- [I]as is[/I] and then parse it according to your needs. I would even go as to creating a struct for holding three short int …

To the OP: When we (at least I) ask you to show up a code and we will try to fix it we say it in a spirit that a car mechanic would say ``Sir, I can't build a car for you, but if you have a defective car, I …

The easiest way, which is in fact the more elegant way to do things would be to declare a struct or class of a [I]card[/I]. Create a vector of such 52 cards and use the standard library's [I]random_shuffle[/I]() [[url]http://www.cppreference.com/wiki/stl/algorithm/random_shuffle][/url] to shuffle it.

>it's working but the code is very complex to me Do not know about the complex part, but the code is wrong, do not follow it. caut_baia, you were wrong in two ways: first, you tried to give the OP a direct answer which can spoil his fun of `getting' …

I can't see where are you comparing a pointer and an int. In the loop condition, msg[size] is a char and i is an integer. Pretty legal. msg[size] is having value 0. So I guess the loop would never execute. PS: If your compiler is generating any error, please post …

Arrays and pointer are closely related in C. But first tell me what book are you using? Anyways, one advice: your scripting languages like Python and Perl makes you feel that programming is fun, this is not the case with C. I am sure you will have to do quite …

>>Yeah, it's .c_str() NO. it is [URL="http://www.cplusplus.com/reference/iostream/stringstream/str.html"].str()[/URL] for string streams.It will return a string object on which you will have to do a .c_str(). So the corrected code would be somewhat like this: [CODE=cplusplus]#include<iostream> #include<sstream> int main() { std::stringstream arg; const float pi=3.145745; arg<<"AdjustSealevel.exe "<<pi; std::cout<<arg.str().c_str(); system( arg.str().c_str() ); } …

I suggest you to change the return type of the `menu()` to int. If the user wants to continue return 1 and he doesn't wants to continue(that is, when he pressed 5), return 0 Then inside your `main()`, you can simply do like this: int main(){ while( menu() ); } …

The if-else is redundant; A number which is smaller than 10, when undergoes modulus operator with divisor as 10 will yeild that number itself. 7%10=7 1%10=1 and so on... Your reverse function is not designed well: You are trying to print the reversed value of the number in the function …

Next time, if you intent to ask a C-related question, check out the C Forums of this website. By the way, a quick example of isalpha is: [CODE=c]#include<stdio.h> int main() { char c; printf("Enter a char"); scanf("%c",&c); if(isalpha(c)) …

Learning from examples is a great way to understand things; only if you understand the example completely before trying to fit your crude analogies. And when you are not able to construct a basic loop, a quick look-up on to your text book wont do harm. I would suggest you …

If at all you want to throw string literals, remember that they are const char* not simply char*. So refactor your code as: [CODE=CPP]void Xhandler(int test) { try { if (test) throw test; else throw "Value is zero"; } catch (int i) { cout << "Caught One! Ex. #: " …

Uh good. But I think you realised your limitation. For sorting integers, there are [URL="http://en.wikipedia.org/wiki/Sorting_algorithm#Summaries_of_popular_sorting_algorithms"]many algorithm available[/URL]. But before that, you need to build a common program to try those. This program includes code to input N numbers into an array. Then it sorts the array using one of the …

[QUOTE=Towel][CODE=cpp]rev1 = 0; { num3 *= 10; num3 += rev1%10; rev1 /= 10; }[/CODE][/QUOTE] Looks like you are trying to loop some statements. But the syntax of the loop is not correct. Read [url]http://www.cplusplus.com/doc/tutorial/control/[/url] (Loops) to find out the correct format.

[URL="http://www.cplusplus.com/reference/iostream/stringstream/"]stringstreams[/URL] are often useful when you want to parse a sting input, specially when you need to do something with words. So make a stringstream and use the >> operator to fetch out one word at a time. Check if that has a .length() equal to 3. If yes, increase …

Use a s[URL="http://www.cplusplus.com/reference/stl/map/"]td::map[/URL]. Create a map<std::string, int>. Scan through the file and insert each of the word to the map with initial value 1.
