var scope example
Raw
var_scope.cpp
// Good idea
for (int i = 0; i < 15; ++i)
{
MyObject obj(i);
// do something with obj
}
// Bad Idea
MyObject obj; // meaningless object initialization
for (int i = 0; i < 15; ++i)
{
obj = MyObject(i); // unnecessary assignment operation
// do something with obj
}
// obj is still taking up memory for no reason
