The correct answer is A. the insertion operator.

The insertion operator is used to write data to an output stream. It is denoted by the insertion operator symbol (<<). The insertion operator can be used to write data of any type, including variables of type float.

The following code snippet shows how to use the insertion operator to write a variable of type float to an output stream:

“`

include

int main() {
float f = 3.14;
std::cout << f << std::endl;
return 0;
}
“`

The output of the above code snippet is:

3.14

The seekg() function is used to reposition the read/write pointer of an output stream. The writeQ function is not a valid function in C++. The put() function is used to write a single character to an output stream.

I hope this helps!
