In the statement template ,

The correct answer is: C. either (a) or (b)

In the statement template , T can be a class or a scalar variable.

A class is a user-defined data type that can be used to create objects. A scalar variable is a variable that can store a single value.

For example, the following code defines a template function that can be used to print the value of any type of variable:

c++
template <class T>
void print(T value) {
std::cout << value << std::endl;
}

The following code calls the print function to print the value of an integer variable, a floating-point variable, and a string variable:

“`c++
int x = 10;
float y = 3.14;
std::string z = “Hello, world!”;

print(x);
print(y);
print(z);
“`

The output of the code is:

10
3.14
Hello, world!
