- “Malloc” is a function in C used to allocate a block of memory on the heap. You just need to tell it how many bytes of memory you want. For example, if I want to allocate enough space for an integer, I would use `int *ptr = (int *) malloc(sizeof(int));`. Here, `siz...
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 runtim
malloc is a standard library function in C and C++ that is used to allocate memory dynamically. It takes a single argument, which is the size of the memory block to be allocated in bytes. The function returns a void pointer to the allocated memory block, or NULL if the allocation fails....
Key Points of realloc() function: realloc() retains the original data in the memory block and resizes it as specified. If the new size is larger, the additional memory is uninitialized (unless calloc() was used for the original allocation). ...

C中malloc的使用(转) malloc函数 原型:extern void *malloc(unsigned int num_bytes); 用法:#include <malloc.h> 功能:分配长度为num_bytes字节的内存块 说明:如果分配成功则返回指向被分配内存的指针,否则返回空指针NULL。 当内存不再使用时,应使用free()函数将内存块释放。
