Article Introduction：The C library's memory allocation function void*realloc(void*ptr,size_tsize) attempts to resize the memory block pointed to by ptr that was previously allocated using a malloc or calloc call. Memory Allocation Functions Memory can be allocated in two ways: Once memory is allocated at compile time, it cannot be changed during execution. Either there is insufficient memory or it is a waste of memory. The solution is to create memory dynamically, i.e. based on the program's needs during execution. The standard library functions used for dynamic memory management are as follows: malloc()calloc()realloc()free()realloc() function is used to reallocate allocated memory. Allocation can be reduced or increased

Article Introduction：Dynamic array C language implementation method: malloc and free: use malloc() to allocate memory, realloc() to change the size, and free() to release memory. Array functions in stdlib.h: realloc() changes the size, calloc() creates and initializes to 0, reallocarray() specifies the number of elements.
