What is the C++ code for Fibbionci series

Question

Fibbionci Series = 0,1,1,2,3,5,8.......i.e.Next number is sum of last two numbers.

Answer 1

#include <iostream>
using namespace std;
int main() {
float a=0,b=1,limit=10000;
while (b<limit)cout<<(a=(b+=a)-a)<<";";
}

Answer 2

#include <iostream>
using namespace std;

int main()
{
int n, t1 = 0, t2 = 1, nextTerm = 0;

cout << "Enter the number of terms: ";
cin >> n;

cout << "Fibonacci Series: ";

for (int i = 1; i <= n; ++i)
{
// Prints the first two terms.
if(i == 1)
{
cout << " " << t1;
continue;
}
if(i == 2)
{
cout << t2 << " ";
continue;
}
nextTerm = t1 + t2;
t1 = t2;
t2 = nextTerm;

cout << nextTerm << " ";
}
return 0;
}
