Chapter 4: Problem 26

Write a C++ statement that prints the message "The number is valid." if the variable temperature is within the range -50 through 150.

Short Answer

Expert verified
Question: Write a C++ statement that checks if the value of a variable 'temperature' is within the range -50 through 150 and prints "The number is valid." if the condition is satisfied. Answer: ```if (temperature >= -50 && temperature <= 150) { std::cout << "The number is valid." << std::endl; }```

Step by step solution

01

Check the range

To verify if the value of the variable 'temperature' is within the range -50 through 150, use an if statement with a logical condition that checks if the value is greater than or equal to -50 and less than or equal to 150: ```cpp if (temperature >= -50 && temperature <= 150) ```
02

Print the message

If the condition in the if statement is satisfied, meaning that the value of the 'temperature' variable is within the given range, use a 'std::cout' statement inside the if statement block to print the message "The number is valid.": ```cpp std::cout << "The number is valid." << std::endl; ```
03

Final Solution

Putting the steps together, the final C++ code should look like this: ```cpp if (temperature >= -50 && temperature <= 150) { std::cout << "The number is valid." << std::endl; } ```

Sometimes either a switch statement or an if/else if statement can be used to implement logic that requires branching to different blocks of program code. But the two are not interchangeable. A) Under what circumstances would an if/else if statement be a more appropriate choice than a switch statement? B) Under what circumstances would a switch statement be a more appropriate choice than an if/else if statement? C) Under what circumstances would a set of nested if / else statements be more appropriate than either of the other two structures? Try to come up with at least one example case for each of the three, where it is the best way to implement the desired branching logic.
