A function heading consists of

A return type, a function identifier and a parameter list

The parameters for a function

are allocated when the function begins execution

The arguments for a function

are provided by the caller

The arguments for a function

are placed in a comma-delimited list in the function call operator

Local variables

are created when the function begins execution

The function call operator

is appended to the function identifier

The parameters in a parameter list

Must have their data types explicitly specified

A local stack variable

is released when a function returns to its caller

A function prototype provides for the compiler

the return type, the function identifier, and the data types of the parameters

In terms of syntax, the only difference between a function implementation and a function prototype is

the implementation has a function body while the prototype has a semicolon
