Breaking change: for scoping change – default is now: /Zc:forScope

  • Article

Original Code:

//sample.cpp
int main() {
for(int i = 0; i < 10; ++i);
for(i = 0; i < 10; ++i) ;
}                                                                                

Error VC2005 issues:

sample.cpp(3) : error C2065: 'i' : undeclared identifier

Code after applying the fix:

//sample.cpp
int main() {
int i;
for(i = 0; i < 10; ++i) ;
for(i = 0; i < 10; ++i) ;
}
