C/C++ Program for the n-th Fibonacci number?

CC++Server Side ProgrammingProgramming

The Fibonacci sequence is a series where the next term is the sum of the previous two terms.The first two terms of the Fibonacci sequence is 0 followed by 1. 

In this problem, we will find the nth number in the Fibonacci series. For this we will calculate all the numbers and print the n terms.

Input:8
Output:0 1 1 2 3 5 8 13

Explanation

0+1=1
1+1=2
1+2=3
2+3=5

Using For loop to sum of previous two terms for next term

Example

#include<iostream>
using namespace std;
int main() {
   int t1=0,t2=1,n,i,nextTerm;
   n = 8;
   for ( i = 1; i <= n; ++i) {
      if(i == 1) {
         cout << " " << t1 ;
         continue;
      }
      if(i == 2) {
         cout << " " << t2 << " " ;
         continue;
      }
      nextTerm = t1 + t2 ;
      t1 = t2 ;
      t2 = nextTerm ;
      cout << nextTerm << " ";
   }
}

Output

0 1 1 2 3 5 8 13
