    cool but simple

    i just learnt about arrays and am good at maths so i wrote two simple progs that calculate squares and the fibonacci numbers here they are
    Code:
    #include <iostream>
    using namespace std; 
    int main()
    {
        int i;
        int fib[20];
    
        fib[0] = 1;
        fib[1] = 1;
    
        for (i = 2; i < 20; i++)
        {
            fib[i] = fib[i-1] + fib[i-2];
        }
    
        for (i = 0; i < 20; i++)
        {
            cout << "The " << i+1 << " element is " << fib[i] << endl;cin.get();
        }
    
    return 0;
    }

            k = i + 1;  
                       
            square[i] = k*k;
            cout << "The square of " << k << " is " << square[i] << endl;cin.get();
        }
