What should be typed to missing code sections in the following C++prc output properly?

The correct answer is option b.<br /><br />The missing code I should be:<br />```cpp<br />#include <iostream><br />```<br />This includes the necessary header file for input and output operations in C++.<br /><br />The missing code II should be:<br />```cpp<br />double f(double a, double b, double c) {<br /> if (b > a) return b;<br /> else if (c > a) return c;<br /> else return a;<br />}<br />```<br />This defines a function `f` that takes three double parameters `a`, `b`, and `c`. It checks if `b` is greater than `a`, and if so, returns `b`. If `c` is greater than `a`, it returns `c`. Otherwise, it returns `a`.
