If the function failed to allocate the requested block of memory, a null pointer is returned. 例1:malloc #include<stdio.h> #include<stdlib.h> int main(void) { int size; printf("请输入元素个数:"); scanf("%d", &size); int* arr = (int*)malloc(size * sizeof(int)); //内存申请...
By presenting code examples, the article illustrates the allocation, utilization, and deallocation of memory for single structs and arrays of structs. It addresses the initialization caveat ofmalloc, advocating forcallocas a solution that not only allocates memory but also initializes it to zero. ...
