C library - malloc() function - The C stdlib library malloc() function is used for dynamic memory allocation. It allocates or reserves a block of memory of specified number of bytes and returns a pointer to the first byte of the allocated space.
In the realm of C programming, efficiently managing memory is crucial for building high-performance applications. One of the tools at a programmer’s disposal for such a task is malloc(), a function that dynamically allocates memory during runtime. Un
size - an unsigned integral value (casted to size_t) which represents the memory block in bytes malloc() Return Value The malloc() function returns: a void pointer to the uninitialized memory block allocated by the function null pointer if allocation fails Note: If the size is zero, the va...

If size is 0, malloc allocates a zero-length item in the heap and returns a valid pointer to that item. Always check the return from malloc, even if the amount of memory requested is small.RemarksThe malloc function allocates a memory block of at least size bytes. The block may be ...
