Question

Write a cout statement so the variable profit is displayed in a field of 12 spaces, in fixed. point notation, with a decimal point and four decimal digits.

Short answer

Answer: You can achieve this by including the iomanip library and configuring the output stream using setw, fixed , and setprecision functions. Here is an example: ```cpp #include #include int main() { double profit = 1234.5678; std::cout << std::setw(12) << std::fixed << std::setprecision(4); std::cout << profit << std::endl; return 0; } ```

Step-by-step solution

Include required libraries

Include the iostream and iomanip libraries in your C++ code. ```cpp #include #include ```

Set up profit variable

Declare a variable of type double named 'profit' and assign it a value to test the output: ```cpp double profit = 1234.5678; ```

Configure the output stream

Use the 'setw', 'fixed', and 'setprecision' functions from the iomanip library to configure the output stream with the desired formatting. ```cpp std::cout << std::setw(12) << std::fixed << std::setprecision(4); ```

Print the profit variable

Now simply print the value of the 'profit' variable. ```cpp std::cout << profit << std::endl; ``` The final code should look like: ```cpp #include #include int main() { double profit = 1234.5678; std::cout << std::setw(12) << std::fixed << std::setprecision(4); std::cout << profit << std::endl; return 0; } ```
