Bevezetés a C ++ Fibonacci sorozatba
A Fibonacci sorozat számsor. Összeállítja a számláncot, amely összeadja az utolsó két számot. A Fibonacci sorozat kiszámítása egyszerű, mivel csak egy utolsó számjegyet kell hozzáadnunk, hogy újabb számot kapjunk. De amikor a számjegyek nagyobbak lesznek, akkor egyre bonyolultabbá válik. Tehát ennek a problémanak a megoldására megvizsgáljuk, hogyan lehet egy Fibonacci sorozat programot létrehozni C ++ nyelven, hogy ez könnyűvé váljon. Nézzük meg, hogyan működik a Fibonacci sorozat.
Legyen f (n) n. Kifejezés.
f (0) = 0;
f (1) = 1;
A sorozat a következő lesz:
1 (1 + 0)
2 (1 + 1)
3 (1 + 2)
5 (2 + 3)
8 (3 + 5)
13 (5 + 8)
21 (8 + 13
…stb
A Fibonacci sorozat létrehozásának logikája
- Inicializálja az első számot 0-ra
- Inicializálja a második számot 1-be
- Adja hozzá az első és a második számot.
- Tárolja a hozzáadási értéket a harmadik számban.
- Nyomtassa ki a harmadik számot.
- A második számot rendelje az első számhoz
- Assange a harmadik számot a második számra.
- Ismételje meg a 3-7. Lépést, amíg az adott szám Fibonacci sorozatát kiszámítják.
Fibonacci sorozat programok C ++ nyelven
Ebben a részben megtudjuk, hogyan lehet megtudni a Fibonacci sorozatot különféle módszerekkel, például rekurzió, hurok, tömb, rekurzió nélkül, stb:
1. A rekurziós módszer nélkül
Kód:
#include
using namespace std;
int main()
(
int first_num = 0, second_num = 1, third_num, i, num;
cout << "Enter random number to print fibonacci series:";
cin >> num;
cout << "Fibonacci Series for a given number:" < cout << first_num < cout << second_num << endl;
for(i = 2; i < num; ++i) //loop will starts from 2 because we have printed 0 and 1 before
(
third_num = first_num + second_num;
cout << third_num << endl;
first_num = second_num;
second_num = third_num;
)
return 0;
)#include
using namespace std;
int main()
(
int first_num = 0, second_num = 1, third_num, i, num;
cout << "Enter random number to print fibonacci series:";
cin >> num;
cout << "Fibonacci Series for a given number:" < cout << first_num < cout << second_num << endl;
for(i = 2; i < num; ++i) //loop will starts from 2 because we have printed 0 and 1 before
(
third_num = first_num + second_num;
cout << third_num << endl;
first_num = second_num;
second_num = third_num;
)
return 0;
)#include
using namespace std;
int main()
(
int first_num = 0, second_num = 1, third_num, i, num;
cout << "Enter random number to print fibonacci series:";
cin >> num;
cout << "Fibonacci Series for a given number:" < cout << first_num < cout << second_num << endl;
for(i = 2; i < num; ++i) //loop will starts from 2 because we have printed 0 and 1 before
(
third_num = first_num + second_num;
cout << third_num << endl;
first_num = second_num;
second_num = third_num;
)
return 0;
)

2. A rekurziós módszer használatával
Kód:
#include
using namespace std;
void FibonacciSeries(int num)
(
static int first_num = 0, second_num = 1, third_num;
if(num > 0)
(
third_num = first_num + second_num;
first_num = second_num;
second_num = third_num;
cout << third_num << endl;
FibonacciSeries(num - 1);
)
)
int main()
(
int num;
cout << "Enter random number to print fibonacci series:";
cin >> num;
cout << "Fibonacci Series for a given number: \n" << endl;
cout << "0" << endl;
cout << "1" << endl;
FibonacciSeries (num - 2); //number-2 is used because we have already print 2 numbers
return 0;
