Final answer:
The default linkage for functions and their parameters depends on the programming language being used.
Step-by-step explanation:
The default linkage for functions and their parameters depends on the programming language being used. In most programming languages such as C and C++, the default linkage is external. This means that the function or parameter can be accessed from other files or modules within the program.
For example, in C++, if a function is declared without a linkage specification, it will have external linkage by default. This allows the function to be called from other files or modules. However, it's important to note that different programming languages may have different default linkages for functions and their parameters.
The question 'What is the default linkage for the functions and their parameters?' pertains to programming, and in this context, it appears to be specific to the C or C++ programming languages. When a function or variable is declared without any explicit linkage specification, it has external linkage by default. This means they are accessible from other files in addition to the one where they are declared.
On the other hand, function parameters (also known as formal parameters) always have no linkage, which means their scope is limited to the function itself; they cannot be accessed from outside the function block. It is important to know about linkage types—external, internal, and none—when managing larger projects with multiple source files.
