Storage allocation refers to the process of determining and assigning memory locations to data structures during runtime. This allocation ensures that these structures are accessible by the program and can be used for efficient data processing.
There are two main types of storage allocation:
Static allocation: This involves allocating memory locations explicitly by the programmer using keywords like int num[10]; or float *ptr;.
Dynamic allocation: This involves allocating memory locations at runtime using functions like malloc() or calloc().
Static allocation is suitable when the size of the data structure is known at compile time. For example, allocating an array of 10 integers requires specifying the size as 10 when declaring the array.
Dynamic allocation is used when the size is not known at compile time or when the data structure needs to be expanded or contracted during program execution. Functions like malloc() and calloc() allow the programmer to specify the amount of memory to allocate and return a pointer to the allocated memory.
In the runtime environment, the compiler determines the memory locations of these data structures and makes them accessible to the program through pointers. These pointers provide a way for the program to access and manipulate the data elements, ensuring efficient data transfer and manipulation.
By understanding storage allocation, programmers can optimize memory usage and improve the performance of their programs by reducing the amount of time spent searching for available memory locations and managing memory allocation and deallocation
