如題，

 `int n;
  cin>>n;
  int a[n];

c++可不可以這樣初始化數(shù)組啊，在VS2010中不可以，在devc++（編譯器gcc） 中可以。

This is the variable length array VLA in the C language C99 standard, which is not supported by the C++ standard. The gcc compiler supports variable-length arrays, but the vc compiler does not. Search for variable length arrays. There will be a lot of information on this (in Chinese and English). Stroustrup, the father of C++, talked about variable-length arrays on his website. There is a short paragraph. If you are interested, you can check it out http://www.stroustrup.com/bs_...

C++ does not support variable length arrays, C supports it
