#include <iostream>
using namespace std;
int main(){
int n=10;
int a[n];
for (int i=0; i<n; i++) {
a[i]=i+1;
cout<<a[i]<<endl;
}
return 0;
}
worked fine in Xcode4 under Mac
as said in books, it should be wrong, why?
so confused~
This a a C99 feature called VLA which some compilers also allow in C++. It's allocation on stack, just as it would be with int a[10]
.
That is C99 feature that allows VLA (variable length array).
Compile it with g++ -pedantic
, I'm sure that wouldn't compile.
