To determine which of the given statements are true, let's analyze each statement one by one.
1. A programming language which does not permit global variables of any kind and has no nesting of procedures/functions, but permits recursion can be implemented with static storage allocation.
This statement is true. Static storage allocation is a memory allocation technique in which memory is allocated to variables and data structures during the compile-time. Since the programming language does not permit global variables and nesting of procedures/functions, the compiler can determine the maximum amount of memory required for the program and allocate it statically. Recursion can still be implemented by using the stack, which is a static data structure.
2. Multi-level access link (or display) arrangement is needed to arrange activation records only if the programming language being implemented has nesting of procedures/functions.
This statement is true. Multi-level access link (or display) arrangement is used to keep track of the activation records of nested procedures/functions. It allows accessing variables and parameters from different levels of nesting. If the programming language does not have nesting of procedures/functions, then there is no need for multi-level access link arrangement.
3. Recursion in programming languages cannot be implemented with dynamic storage allocation.
This statement is false. Recursion can be implemented with dynamic storage allocation. Dynamic storage allocation is a memory allocation technique in which memory is allocated and deallocated at runtime. Recursive function calls can create activation records on the stack dynamically as they are called and deallocated when they return, allowing recursion to be implemented.
4. Nesting of procedures/functions and recursion require a dynamic heap allocation scheme.
This statement is false. Nesting of procedures/functions and recursion can be implemented without a dynamic heap allocation scheme. As mentioned earlier, recursion can be implemented with dynamic storage allocation on the stack. The stack provides a natural way to manage the activation records of nested procedures/functions.
5. Programming languages which permit a function to return a function as its result cannot be implemented with a stack-based storage allocation scheme for activation records.
This statement is true. A stack-based storage allocation scheme for activation records assumes a fixed-size activation record structure. However, if a programming language allows a function to return a function as its result, the size of the activation record may vary depending on the returned function. This requires a more flexible memory allocation scheme, such as heap allocation, to handle the varying sizes of activation records.
In conclusion, the true statements are:
- Statement 2: Multi-level access link (or display) arrangement is needed to arrange activation records only if the programming language being implemented has nesting of procedures/functions.
- Statement 3: Recursion in programming languages cannot be implemented with dynamic storage allocation.
- Statement 5: Programming languages which permit a function to return a function as its result cannot be implemented with a stack-based storage allocation scheme for activation records.
