What's wrong with this code? ... please help :(

Question

#include <iostream>
#include <cmath> // needed for math functions like sqrt()
#include <iomanip>
using namespace std;

int main()

{

float a, b; // the smaller two sides of the triangle
float hyp; // the hypotenuse calculated by the program

cout << "Please input the value of the two sides" << endl;
cin >> a >> b;
hyp = sqrt(exp(a) + exp(b));

// Fill in the assignment statement that determines the hypotenuse.
cout << setprecision(2) << fixed << showpoint;
cout << "The sides of the right triangle are " << a << " and " << b << endl;

cout << "The hypotenuse is " << hyp << endl;

return 0;
}

-----------------------
I put in the value of two sides: 9 3
I expected the output of hyp is 9.49 but I got 90.13 ....
How can I fix it? :(

Answer 1

it's not
exp(a)+exp(b)

it is
pow(a,2)+pow(b,2)

I think there is no need for

cout << setprecision(2) << fixed << showpoint;
