To Earl Cash : Já taky ne, to až když jsem využil f-ci VS navrhování tříd, tak to tam VS dalo...

Jak spočítám úhel odrazu, znám-li úhel dopadu(vyjádřený vůči vodorvné rovině) a plochy, od kterých se předmět odráží jsou horizontální nebo vertikální?
Potřeboval bych tytto vědomosti a ve škole jsme se to ještě neučili....

Pokud by to bylo trochu polopaticky – nevadilo by.

1.Nechápu proč máš ve f-ciSoucet urcenou navr.hodnotu int a pretypovavas na double?
2. co znamena

float cin >> a;

#include <iostream>



#include <math.h> 



int Soucet(int x, int y)



{



      return ((x*x)+(y*y));



}







int main()



{



	using std::cout;

	using std::cin;

	int a, b, c;

	cout << "strana a=";

	cin >> a;



      cout << "strana b=";



      cin >> b;



      c=Soucet(a,b);



    double d = sqrt((double)c);



      cout << "x=" << d <<"\n";



      cout << "\nKonec...\n\n";



 	cin.get();



      return 0;



}

Aha, děkuji za odpověď. ASi budu používat once....

Co používat? #pragma once nebo #ifndef a #define?
Osobně se mi víc zamlouvá once, ale v žádné literatuře ani na interentu jsem o něm neslyšel...

A kde konkrétne sa o tom v sekcii Building SDL píše ??

EDIt: A DirectX SDk mam

Tak jsem si to prostudoval,ale tam pisi,ze se to ma kompilovat ala multi-threaded DLL.Ale ja bych to rad zkompiloval jako Multi-threaded - rad bych se zbavil závislostí na CRT - dle jedne rady zde na programujte.com, myslim, ze primo od vas.

Snazim se prekompilovat SDL na Multi-threaded.Avsak pri kompilaci dostanu chyby v knihovne cstdio,mktera by podle me mela byt bez chyb

Nevím, co dělám špatně, ale asi tak po 20 zkompilováních mi můj program začne hlásit, že se nepodařilo najít MSVCR90.dll - přitom ji mám..Ale stačí založit nový projekt, vložit do něj existující soubory azase můžu 20x kompilovat....
