How to Generate a Fibonacci series in C++ Programming?

#include <iostream>
using namespace std;
int main()
{
int i, a=0,b=1,c, num;
cout << "Enter Number for how many times generate Series: ";
cin >>num;
cout << "Fibonaci Series is: \n";
for(i=0;i<num;i++)
{
c=a+b;
a=b;
   b=c;
cout << "\t" <<c<<endl;
}
return 0;
}

Square root upto given Number.

#include <iostream>
//#include <math.h>
using namespace std;
int main()
{
int num;
cout << "Enter Number upto which u want to take square: ";
cin >> num;
for (int q=1;q<=num;q++)

cout << "Square of " << q << " is " << q*q <<endl;

return 0;
}
