A block is a statement containing its own local data declaration. The concept of a block is originated with ALGOL. The block-structured language permits an array with adjustable length. The main feature of blocks is their bracketing structure (begin and end used in ALGOL) in which they can define their ... Read More

Stack Allocation scheme is the simplest Run-Time Storage Management Technique. The storage is allocated sequentially in the stack beginning at one end. Storage should be freed in the reverse order of allocation so that a block of storage being released is always at the top of the stack.A program consists ... Read More

The stack allocation is a runtime storage management technique. The activation records are pushed and popped as activations begin and end respectively.Storage for the locals in each call of the procedure is contained in the activation record for that call. Thus, locals are bound to fresh storage in each activation, ... Read More

It is the simplest allocation scheme in which allocation of data objects is done at compile time because the size of every data item can be determined by the compiler. The main function of static allocation is to bind data items to a particular memory location. The static memory allocation ... Read More

There are various issues in programming language design that affect the utilization of storage by a running program. There are several elements to which storage must be allocated to execute the object program. Storage space is majorly required for object programs and user-defined data structures, variables, and constants. There is ... Read More

The compiler demands a block of memory for the operating system. The compiler utilizes this block of memory executing the compiled program. This block of memory is called storage management. One of the important tasks that a compiler must perform is to allocate the resources of the target machine to ... Read More

Symbol Table is a data structure that supports an effective and efficient way of storing information about various names appearing in the source program. These names are used in the source code to identify the different program elements, like a variable, constants, procedures, and the labels of statements.The symbol table ... Read More
