Description. Declaration Syntax • General form of a declaration: declaration-specifiers declarators ; • Declaration specifiers describe the properties of the variables or functions being declared. Building Functions The builder of a function (a programmer) is responsible for the declaration (also known as prototype) and the definition.

If the following function will throw a string exception, then void myFunction( ); a. the function definition and declaration should have a throw list b. the function definition, but not the declaration should have a throw list c. the function should have an empty throw list.

This is illegal because tripler expects a single integer variable, and the argument here is an entire array. Download App. 6.23 Analyze the following statements. Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function statement within an enclosing function is irrelevant.
