So no, there is no guarantee the elements will be iterated over in the order they were inserted. FYI, you can iterate over an unordered_map more … Read more
On a 64-bit machine running in 64-bit mode: echo %programfiles% ==> C:\Program Files echo %programfiles(x86)% ==> C:\Program Files (x86) On a 64-bit machine running in 32-bit (WOW64) mode: echo %programfiles% ==> C:\Program Files (x86) echo %programfiles(x86)% ==> C:\Program Files (x86) On a 32-bit machine running in 32-bit mode: echo %programfiles% ==> C:\Program Files echo %programfiles(x86)% … Read more
