Hi friends, would like to share something if Anyone wanted to know the C++ fibonacci program in simple way can go through this Code: // Program name : test051.c // Print Fibonica series of nth numbers #include <iostream.h> #include <conio.h> void main() { int n, first = 0, second = 1, third = 0; clrscr(); cout <<"Enter Fibonica n th number : "; cin >> n; cout<<first<<" "<<second<<" "; for(int i = 3; i <= n; i++) {third = first + second; cout<<third<<" "; first = second; second = third; } getch(); } Output Enter Fibonacci nth number : 10 0 1 1 2 3 5 8 13 21 34 Enter Fibonacci nth number : 15 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 As i am a beginner,i am learning all programming languages in simple way with easy solutions.
