我真的可以用方括号初始化数组吗? [英] Can I really initialize an array with round brackets?

问题描述

有时候，我在程序代码的一个地方打错了文字:

Occasionaly, I've made a typo in one place of code of my program:

int a = 10;  
char* b = new char(a);

错误很明显:我写了()而不是[].奇怪的是...代码已正确编译，已在调试器中正常运行.但是，执行了这些行的功能后，调试器外部的已编译.exe崩溃了.

Error is obvious: I've written () instead of []. The strange thing is... code compiled ok, it ran in debugger ok. But compiled .exe outside of debugger crashed a moment after function with these lines was executed.

第二行代码真的合法吗?如果是的话，对编译器意味着什么?

Is second line of code really legitimate? And if it is, what does it mean to compiler?

推荐答案

它是单个字符，其数值为a，在本例中为10.知道，指针不仅指向数组.

It's a single char with the numerical value of a, in this case 10. Pointers don't only point to arrays, y'know.
