Chapter 3, Problem 12SA
Explanation of Solution
The output of the program is given below:
9.00^3.20 = 1131.30
5.0^2.5 = 55.90
sqrt(48.35) = 6.95
static_cast<int>(sqrt(pow(y, 4))) = 10
Length of str = 47
The variables x and y are declared of double type and initialized. The variable str is just declared as a string type.
The first cout statement uses the manipulators fixed, showpoint and setprecision to fix the output numbers to a fixed decimal format. It also sets the output stream to display the decimal point and the decimal part of a number even if the decimal part is zero. Finally, the precision of the output is set to 2 decimal places.
The second cout statement displays the value of x (set to 9.0) raised to the power of y (set to 3.2) using the pow function specified in the cmath header file.
The third cout statement displays the value of 5...
