C ++ compiler error [Error] name lookup of 'i' changed for ISO '

In VC 6 , the scope of the range is a function of i scope, can still be used for the outer loop variable i that is:

for (int i = 0; i < n; ++i) { 
        //…… 

}

cout<<i<<endl;

So the compiler;

for (int i = 0; i < n; ++i) { 
        //…… 
} 
int i = 5; 

So the compiler error.

 

In DEV C ++ in, I scope is limited to the for loop , namely:

for (int i = 0; i < n; ++i) { 
        //…… 

}

cout<<i<<endl;

So the compiler error.

 

for (int i = 0; i < n; ++i) { 
        //…… 
} 
int i = 5; 

So the compiler through.

 

 

The same in VS (vs2015) I also tested, with the results of the above in dec.
