Question

Write a stub for the function whose function declaration is given next. Do not write a whole program, only the stub that would go in a program. Hint: It will be very short. double rain_prob(double pressure, double humidity, double temp); //Precondition: pressure is the barometric pressure in inches of mercury, //humidity is the relative humidity as a percent, and //temp is the temperature in degrees Fahrenheit. //Returns the probability of rain, which is a number between 0 and 1 // 0 means no chance of rain. 1 means rain is \(100 \%\) certain.

Short answer

Question: Create a stub function based on the following function declaration: double rain_prob(double pressure, double humidity, double temp); Answer: A stub function is created by providing a default or neutral return value without implementing the actual functionality. Here is the stub for the given function declaration: ```cpp double rain_prob(double pressure, double humidity, double temp) { return 0.5; } ```

Step-by-step solution

1. Function declaration

First, we need to write the given function declaration. ```cpp double rain_prob(double pressure, double humidity, double temp); ```

2. Create a function stub

Next, we create a function stub for the given function declaration. A stub generally only has one return statement that returns a default or neutral value. ```cpp double rain_prob(double pressure, double humidity, double temp) { return 0.5; // The stub returns a default neutral value of 0.5 } ``` The completed stub for the rain_prob function is as follows: ```cpp double rain_prob(double pressure, double humidity, double temp) { return 0.5; } ```
