Another useful STL algorithm is reverse(). This algorithm reverses the order of elements in a specified sequence. reverse() takes two iterators that mark the sequence’s beginning and end, respectively. Here is an example of reversing the order of a char array:
#include #include using namespace std; int main() { char arr[4] = {'a','b','c','d'}; reverse(arr, arr+4); // arr is now "dcba" } Remember that the second argument of reverse() must point one element past the array’s bounds. Here’s an example of applying reverse() to a vector object:
int main() { char arr[]= {'a','b','c','d'}; vector vc (arr, arr+4); // initialize vc reverse(vc.begin(), vc.end()); }
