What is the output of the following program? (2, 3, 6, 8)
#include <iostream>
#include <cmath>
#include <string>
#include <iomanip>
using namespace std;
int main()
{
double x, y;
string str;
x = 9.0;
y = 3.2;
cout << fixed << showpoint << setprecision (2);
cout << x << "^" << y << " = " << pow(x, y) << endl;
cout << "5.0^2.5 = " << pow(5.0, 2.5) << endl;
cout << "sqrt (48.35) = " << sqrt (48.35) << endl;
cout << "static_cast<int>(sqrt(pow (y, 4))) = "
<< static_cast<int>(sqrt(pow (y, 4))) << endl;
str = "Predefined functions simplify
cout << "Length of str = " << str.length() << endl;
