Nothing, except when v is an array, in which case v.size() will not compile. Jan 17, 2019 at 8:57pm Grime(651) Is it better than sizeof(arr)/sizeof(arr[0]) for c-strings? edit: I found this at cppreference for std::size, ...
it says that fish in rect, which is of non-class type 'CRectangle()'. When building this I originally got it to work without vectors but it still needed to have CRectangle rect(1,1,1,1) or something similar in main even though the 1's weren't being used. Has anyone got any ide...

The integer is 10 The result should be 11, 12, and 13 As a side note, is there a way to add a repeating number to an integer to infinity? Example...the integer is 10 and I want to add 4 to it. Then 4 again. And again. And again in a loop ...

If we had in the 'Magic' above a foo.reserve( N );, then we could do N push_backs before size==capacity. There are two ways to access an element in the vector: 12 foo[i] foo.at(i) The at() should give a better error, when you use invalid index. Oct...
danielwow(9) Im trying to compile a source that seems correct however, i get a runtime error any ideas? Though, i did comment out the display and it ran but nothing ran so im guessing the error is somewhere in the display function. ...
