C / C ++ Pointers vs ReferencesPointers, UseReferences, References
链接:C/C++ Pointers vs Java References - GeeksforGeeks Java 没有指针;Java 有引用。 引用:引用是指向其他事物的变量,可用作其他事物的别名。 指针:指针是存储内存地址的变量,目的是作为存储在该地址的内容的别名。 因此,指针就是引用,但引用不一定就是指针。指针是引用概念的一种特殊实现方式,而且这个术语往往...

Does C language support references? No. The concept of reference has been added to C++, not in C. So if you run the following code, C compiler will object then and there. #include<stdio.h> #include<conio.h> int main(void) {
I am struggling to understand what is the purpose of pointers and references? why do we need them? How are they different from one another? Any practical use of pointers and references would be helpful. Thanks c++pointerscppreferences
