Short Answer

Expert verified
A) #include (iostream) B) #include {iostream} C) #include D) #include [iostream] E) All of the above Answer: C) #include

Step by step solution

01

Identifying the correct way to include the iostream header file

To include the "iostream" header file in a C++ program, we need to use the #include directive followed by the name of the header file enclosed in angle brackets.
02

Evaluating each option

Let's go through each statement and see if it's the correct way to include the "iostream" header file. A) #include (iostream): This option is incorrect because the header name should be enclosed in angle brackets instead of parentheses. B) #include {iostream}: This option is also incorrect because the header name should be enclosed in angle brackets instead of curly braces. C) #include : This option is the correct way to include the "iostream" header file, as it is enclosed in angle brackets. D) #include [iostream]: This option is incorrect because the header name should be enclosed in angle brackets instead of square brackets. E) All of the above: Since there is only one correct option, this option is also incorrect.
03

Conclusion

The correct way to include the iostream header file in a C++ program is #include . Therefore, the correct answer is option C.
