Uvod v Fibonaccijeve vrste v C ++

Fibonaccijeva serija je niz števil. To naredi verigo števil, ki sestavijo zadnji dve številki. Izračun Fibonaccijeve serije je preprost, saj moramo samo dodati zadnjo dvomestno številko, da dobimo še eno številko. Toda v nekem trenutku, ko število števk postane večje, postane precej kompleksno. Torej bomo za rešitev te težave videli, kako lahko v jeziku C ++ izdelamo Fibonaccijev program serije, da bo postalo enostavno. Poglejmo, kako dejansko deluje serija Fibonaccije.

Naj bo f (n) n. Pojem.

f (0) = 0;

f (1) = 1;

Serije bodo naslednje:

1 (1 + 0)

2 (1 + 1)

3 (1 + 2)

5 (2 + 3)

8 (3 + 5)

13 (5 + 8)

21 (8 + 13)

…in tako naprej

Logika za ustvarjanje Fibonaccijeve serije

1. Prvo številko inicializirajte na 0
2. Drugo številko inicializirajte na 1
3. Dodajte prvo in drugo številko.
4. V tretjo številko shranite vrednost dodajanja.
5. Natisnite tretjo številko.
6. Prvi številki dodelite drugo številko
7. Tretjo številko povežite z drugo številko.
8. Ponavljajte korak 3 do korak 7, dokler ni izračunana serija Fibonaccije za dano število.

Programi Fibonaccijeve serije v C ++

V tem razdelku bomo videli, kako najti Fibonaccijevo vrsto z različnimi metodami, kot so rekurzija, zanka, matrika, brez rekurzije itd.:

1. Brez metode rekurzije

Koda:

#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. Z uporabo metode rekurzije

Koda:

#include

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;
