using namespace std;
int main()
{
	int num = 1, pre_num = 0, sum, n;
	do
	{
		cout << "Enter number of terms 'n'of Fibonacci series: ";
		cin >> n;
		cout << "Fibonacci series: ";
		for (int i = 0; i < n; i++)
		{
			sum = num + pre_num;
			pre_num = num;
			num = sum;
			cout << num << " ";
		}
	return 0;
}

c++ program to print fibonacci series

#include<iostream>
using namespace std;
int main()
{  
   int n;
   int a[n];
   cout<<"Enter no of terms:-t";
   cin>>n;
   a[0]=0;
   a[1]=1;
   cout<<a[0]<<" "<<a[1];
   for (int i = 2; i <=n; i++)
   {
       a[i]=a[i-1]+a[i-2];
       cout<<" ";
       cout<<a[i];
   }
 return 0;
