Fibonacci Series Program in C++ and C with flowchart

Fibonacci Series Program in C++ and C with the flowchart.

Fibonacci Series Program in C++ with “do-while loop”

#include<iostream>

using namespace std;

int main()

{

int a=0,b=1,t,j=1,num;

cout<<"enter the limit ";

cin>>num;

cout<<"The Fb Series is "<<a<<b;

{

t=a+b;

cout<<t;

a=b;

b=t;

j++;

}

while(j<=num);

cout<<endl;

}

Output

enter the limit 3

The Fb Series is 01123

What lines will execute if “j=1”?

1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.

What lines will execute if “j=2”?

1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, (T), 10, 11, 12, 13, 14, 15, 16, 17

What lines will execute if “j=3”?

1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, (T), 10, 11, 12, 13, 14, 15, 16, 17, 18, 10, 11, 12, 13, 14, 15, 16, 17, 18

Fibonacci Series Program in C++ with for loop

#include<iostream>

using namespace std;

int main()

{

int x;

int num;

int next;

int fst=0;

int sec=1;

cout<<"Enter Nubmer the Number To Start Series: ";

cin>>num;

cout<<"Numbers In The Fibonacci Series Are: \n";

for(x=0; x<num; x++)

{

cout<<"\n"<<fst;

next = fst + sec;

fst = sec;

sec = next;

}

cout<<"by";

}

Output
