Question
Which of the following is true of function templates?a. All function templates begin with the keyword class.
b. Every formal type parameter is preceded by either keyword typename or template.
c. Formal type parameters act as placeholders for built-in types or user-defined types and are used to specify the types of arguments to the function, to specify the return type of the function, and to declare variables within the body of the function definition.
d. A programmer must define a separate function template for each template function specialization to be used in the program.

Q:
Which of the following statements is false?a. An enumeration's constants have integer values.b. An unscoped enum's underlying type is independent of its constants' values but is guaranteed to be large enough to store those values.c. A scoped enum's underlying integral type is int, but you can specify a different type by following the type name with a colon (:) and the integral type. For example, we can specify that the constants in the enum class Status should have type unsigned int, as in enum class Status : unsigned int {CONTINUE, WON, LOST};d. A compilation error occurs if an enum constant's value is outside the range that can be represented by the enum's underlying type.
