Chapter 16: Problem 37

\(\mathrm{T} \quad \mathrm{F} \quad\) A class object passed to a function template must overload any operators used on the class object by the template.

Short Answer

Expert verified

Answer: True (T)

Step by step solution

Understanding function templates

A function template is a versatile version of a function that can be used with various data types without modifying its code. The function template takes one or more type parameters or template parameters that act as a placeholder for specific data types when calling the function.

Understanding operator overloading

Operator overloading allows us to redefine the behavior of the existing operators so that they can also perform operations on user-defined data types or class objects. In C++, we can overload most really-existing operators for our custom classes.

Connecting function templates and operator overloading

When passing class objects as arguments to a function template, we might need to use certain operators on those class objects within the template. For example, we might want to compare two class objects with the equality operator (==) or add two class objects with the addition operator (+). In this case, the operator overloading allows us to use these operators for our custom class objects.

Analyzing the statement

The statement, "A class object passed to a function template must overload any operators used on the class object by the template," refers to the necessity of overloading operators for the class object to be used within a given function template. This is indeed true, as if the operators are not overloaded, the function template might not understand how to perform the requested operation on the class objects.

Conclusion

After understanding function templates and operator overloading in C++ and connecting their relationship, we can conclude that the original statement is True (T). A class object passed to a function template must overload any operators used on the class object by the template.
