The Yoyo Cell
SITUATION: "You, walking down the street, stressed about your discharged phone and bored to death... :-("Talking about the presented situation (which happens to everybody pretty often), we see that it comes with 2 problems, so 2 necessities. First: a phone charger and 2nd: a toy.
The Yo yo Cell |
It has the basic functions of a phone and by dragging out its built-in earphones cable it turns into a yo yo. Playing with the yo yo, you charge the phone!!! Isn't it perfect?
The Yoyo charge |
Would you buy a yo yo cell or a yo yo charger? I think the 2nd option is really interesting.

C++: Diferente intre Borland C++ si MinGW
Diferentele dintre aceste 2 medii de programare sunt putine la nivel incepator, mediu si nu foarte avansat, insa la nivel profesionist acestea incep sa se inmulteasca. In acest articol, va voi prezenta CELE MAI SEMNIFICATIVE 7 DIFERENTE DINTRE BORLAND C++ SI MINGW, suficiente pentru categoria intai enumerata.
- Functia principala ("main") nu mai poate fi declarata de tip "void" (ca in Borland), ci doar de tip "int", implicand aparitia randului de comanda "return 0;", la sfarsitul programului.
- Dupa anumite biblioteci (precum "fstream", "iostream" si "algorithm") mai trebuie introdusa comanda pentru alocare de spatiu: "using namespace std;".
- ".h" - ul de la finalul tuturor bibliotecilor din Borland dispare in unele cazuri (ex. "fstream" si "iostream"), iar in celelalte cazuri se pastreaza (ex. "math.h" si "stdio.h") si se poate inlocui cu un "c" la inceput, ambele fiind corecte in MinGW (adica se poate scrie "stdio.h" sau "cstdio").
- Limitele se maresc foarte mult pentru tipurile de declarare a varibilelor, "int" ajungand aproape cat vechiul "long"!!!
- Programul primeste un "WARNING" daca nu este dat un "Enter" la sfarsitul sursei, astfel incat cursorul mouse-ului sa fie pe randul urmator, ca in imagine:

Introduction in Origami
The base of origami is folding the coloured paper, for representing different animals, birds, boats, flowers etc. obtained by various combinations of surfaces and lines. There is the possibility of creating a large diversity of figurines, which confers a plus of originality to this art.
Some people treated origami as a simple game, but the most of them considered it as art, due to the possibility to represent creatively and realistically different subjects. The true beauty of the origami art is...

C++: Ciurul lui Eratostene
TEORIA:
Pasul 1: Cream un sir de numere consecutive (de la 2) pana la maximul posibil precizat in restrictiile problemei.
Pasul 2: Incepem cu primul numar (2) si intr-un sir auxiliar cu exact atatea elemente ca primul (in care initial toate sunt 0) marcam multiplii numarului, prin transformarea in 1 a valorilor corespunzatoare acestora, din al IIlea sir.
Pasul 3: Luam urmatorul numar pentru care valoarea sa din al IIlea sir este 0 si repetam pasul 2 pentru numarul respectiv.
Pasul 4: .......

Proprietatile patratului perfect
- Daca p/n2 => p2/n2 (p=un nr. prim)
- k=n2. Daca Dk={1, n, n2} => n=un nr. prim
- Un nr. este patrat perfect daca:
- se poate scrie ca n2
- Un nr. nu este patrat perfect daca:
- ultima cifra a sa este 2, 3, 7 sau 8
- ultimele doua cifre ale sale nu se gasesc printre: 00, 01, 21, 41, 61, 81, 04, 24, 44, 64, 84, 25, 16, 36, 56, 76, 96, 09, 29, 49, 69, 89
- este de forma: M3+2, M4+2, M4+3, M5+2, M5+3, ...
