Chapter 3: Problem 17

Write a cout statement so the variable totalAge is displayed in a field of 12 spaces, in fixed point notation, with a precision of 4 decimal places.

Short Answer

Expert verified

Answer: To display the totalAge variable in a formatted way, you should include the required headers (iostream and iomanip), initiate the main() function, declare the totalAge variable, set field width and precision with setw() and setprecision() functions, and finally use the cout statement to print the totalAge. The complete code is as follows: ```cpp #include #include int main() { double totalAge = 29.3456; std::cout << std::setw(12) << std::setprecision(4) << std::fixed; std::cout << totalAge << std::endl; return 0; } ```

Step by step solution

Include Required Headers

First, we need to include the headers for input and output operations as well as for formatting the output. So, we'll include iostream and iomanip headers: ```cpp #include #include ```

Initiate main() Function

Now, create the main() function where the cout statement will be placed: ```cpp int main() { } ```

Declare totalAge Variable

Inside the main() function, declare the totalAge variable and assign it a value (for example, let's set totalAge to 29.3456): ```cpp double totalAge = 29.3456; ```

Set Field Width and Precision

Now, configure the cout statement to display totalAge in a field of 12 spaces and with a precision of 4 decimal places using setw() and setprecision() functions inside the iomanip header: ```cpp std::cout << std::setw(12) << std::setprecision(4) << std::fixed; ```

Print the totalAge

Finally, use the cout statement to display the totalAge variable after applying the required format: ```cpp std::cout << totalAge << std::endl; ```

Complete Code

Here's the full code with all the steps combined: ```cpp #include #include int main() { double totalAge = 29.3456; std::cout << std::setw(12) << std::setprecision(4) << std::fixed; std::cout << totalAge << std::endl; return 0; } ``` When you compile and run the code, it will display the totalAge variable in a field of 12 spaces, in fixed point notation with a precision of 4 decimal places.
