Snippet
#include <iostream> int main() { //define first two fibonacci series numbers. int fib1 = 0; int fib2 = 1; //declare the variable to store the next number of fibonacci series int fib3; //declare the variable to store how many numbers to be printed. Default is 2. int numbers = 2; //the counter to keep track how many numbers are printed. int counter = 2; //Ask user how many numbers of the fibonacci series need to be printed. std::cout << "How many Fibonacci number you need ? : " ; //Store the number. std::cin >> numbers; //If number entered is less than 3, exit the program. if (numbers < 3) return 0; //Print the first two element. std::cout << fib1 << "\t" << fib2; //do-while loop to calculate the new element of the series and printing the same. do { counter++; fib3 = fib1 + fib2; std::cout << "\t" << fib3; fib1 = fib2; fib2 = fib3; } while (counter <= numbers); std::cout << std::endl; system("pause"); return 0; }
