    According to given question the answer will be 3.1 not 3.14 means you will get the answer up to one decimal place. If you want the answer up to 2 decimal place you have to write code as given below.
    void main()
    {
    float x= 3.1496;
    cout << fixed;
    cout << setprecision(2) << x;
    }
