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