Int a 100 integer b 100
int (*b) [100] declares b to be a pointer to an array of 100 integers. The line with malloc allocates the memory to which pointer b points to. *b dereferences the pointer and thus gives us the recently allocated memory. b [1] is just an address, it can be rewritten as b + 1. That address is 100 integers further from what b points to. Nettet25. mai 2024 · 一、int和Integer的区别 两者的区别主要体现在以下几个方面: 1、数据类型不同:int 是基础数据类型,而 Integer 是包装数据类型; 2、默认值不同:int 的默认 …
