问题描述

我是编程新手.谁能告诉我声明和定义之间的区别.

I am new to programming. Can anyone tell me difference between declaration and definition.

推荐答案

声明是可以的，您将在定义它.定义就是对诺言的兑现.

外部诠释//减速
int i;//defination

int i = 10;//定义+初始化

Declaration is promise, that you will be defining it. Definition is fulfillment of that promise.

Like,
extern int i; //deceleration
int i;//defination

int i = 10;//definition + initialization
