int main(){
	int a{0},b{1},count{},c{};
	cin >> count;
	for (int i = 0; i < count; ++i)
	{

		a = c;
	}
}

fibonacci sequence c++

using namespace std;

int main ()
{
    int num1, num2, num3, input; 
    num1 = 0;
    num2 = 1;
    cout << "How many nums in sequence do you want to see: "; 
    cin >> input; 
    cout << num1 << " " << num2 << " "; 

    for(int i = 2; i < input; i++) // runs through every element but first two 
    {
        num3 = num1 + num2;

        num1 = num2; 
        num2 = num3;
