Sometimes the size of the array you declared may be insufficient. To solve this issue, you can allocate memory manually during run-time. This is known as dynamic memory allocation in C programming. To allocate memory dynamically, library functions aremalloc(),calloc(),realloc()andfree()are use...
C programming - Dynamic Memory AllocationOverview:Dynamic memory allocation is a powerful feature in C that allows you to allocate memory during runtime, which is especially useful when the amount of memory required cannot be determined before execution. The four key functions are malloc(), calloc...
This is known as dynamic memory allocation. If you're programming in C, this probably means using the memory allocation and release functions, mallocO and f ree(). Dynamic memory allocation and the structures that implement it in C are so universal that they're usually treated as a black ...
C Programming questions and answers section on "Memory Allocation" for placement interviews and competitive exams: Fully solved C Programming problems with detailed answer descriptions and explanations are given for the "Memory Allocation" section.
The Dynamic memory allocation enables the C programmers to allocate memory at runtime. The different functions that we used to allocate memory dynamically at run time are − malloc () − allocates a block of memory in bytes at runtime. calloc () − allocating continuous blocks of memory...
Object-Oriented Memory Allocation The functionsmallocandfreeare often used in the C Programming Language. In C++, the operatorsnewanddeleteare used instead. Thenewanddeleteoperators perform the same operation asmallocandfree, respectively. However, the new and delete operators are often used to alloc...
Allocate and Deallocate the Memory Using C Standard Library Benefits of Dynamic Memory Allocation Using the Standard Library The compiler automatically controls the memory allotted to variables in other programming languages like Java and Python. But in C++, this is not the case. Since its creatio...

Memory Allocation in C Language Memory allocation is performed using themalloc()function in C Language. This method gives back a reference to a memory block with the specified size. The pointer value is used to access the allocated memory block. Once the memory is not required, it needs to ...
Allocate Memory Usingcallocfor Initializing to Zero in C callocis a function in the C programming language used for dynamically allocating memory from the heap during runtime. It stands forcontiguous allocation, and it allocates a block of memory for an array of elements, initializing the memory...
