Choose the false statements:1. Control stack keeps track of live proce...
Control Stack and Activation Records:
- The statement 1 is true. The control stack is used to keep track of live procedure activations in a program. It stores information about the current state of each procedure or function being executed.
- Statement 2 is also true. Activation records, which contain information such as local variables, parameters, and return addresses, can be managed effectively using a stack data structure. Each time a new procedure is called, a new activation record is pushed onto the stack, and when the procedure completes, the record is popped off the stack.
Dangling References:
- The statement 3 is false. A dangling reference is not a reference to deallocated storage; instead, it refers to a situation where a program tries to access memory that has already been released or is invalid. This can lead to unpredictable behavior and bugs in the program.
Therefore, the correct answer is option 'D', as all the statements are not false.
