Shuffling an array c++
WebMay 1, 2009 · c++. /* This is a shuffling program. It takes an array of integers and "shuffles" it so the order is more or less "random" by swapping array indexes. The more swaps you make, the more random the order will appear. This particular example simply takes an array of 10 integers containing the numbers 0 through 9 and shuffles it. WebAug 9, 2014 · void shuffle(int array[], const int size); This is a very C like interface. It also limits you to using C-Arrays (In C++ there are lots of container types). So I would change this to use iterators. template void shuffle(T begin, T end); You can still use the same function with your C array (as pointers implement the iterator interface).
