Questions: Which will be the correct output displayed from the following code? float dollars = 5.0000000; cout << fixed << showpoint << setprecision(4); cout << dollars << endl; a. 5.0 b. 5.00 c. 5.000 d. 5.0000 e. 5.00000

The answer is (d): 5.0000

Explanation for each option: a. 5.0 - This is incorrect because the setprecision(4) manipulator specifies that the output should have four digits after the decimal point. b. 5.00 - This is incorrect because it only shows two digits after the decimal point, whereas setprecision(4) requires four. c. 5.000 - This is incorrect because it only shows three digits after the decimal point, whereas setprecision(4) requires four. d. 5.0000 - This is correct because setprecision(4) specifies that the output should have four digits after the decimal point, and fixed ensures that the precision is applied to the decimal part. e. 5.00000 - This is incorrect because it shows five digits after the decimal point, whereas setprecision(4) requires four.

Summary: The correct output displayed from the given code is 5.0000, which corresponds to option (d).
