To do: Using the C++ reverse_copy() to reverse the order of the elements within a source range while copying them into a destination range in C++ programming
To show: How to use the C++ algorithm, reverse_copy() to reverse the order of the elements within a source range while copying them into a destination range in C++ programming
// C++ STL algorithm, reverse_copy()
#include <vector>
#include <algorithm>
#include <iostream>
using namespace std;
int main(void)
{
// vector container
vector <int> vec1, vec2(11);
// vector iterators
vector <int>::iterator Iter1, Iter2;
int i;
// push data into vector container
for(i = 10; i <= 20; i++)
vec1.push_back(i);
// print the data
cout<<"The original vec1 vector data is: ";
for(Iter1 = vec1.begin(); Iter1 != vec1.end(); Iter1++)
cout<<*Iter1<<" ";
cout<<endl;
// reverse the elements in the vector
reverse_copy(vec1.begin(), vec1.end(), vec2.begin());
cout<<"\nThe copy vec2 vector data of the reversed vec1 vector is: ";
for(Iter2 = vec2.begin(); Iter2 != vec2.end(); Iter2++)
cout<<*Iter2<<" ";
cout<<endl;
cout<<"\nThe original vec1 vector unmodified as: ";
for(Iter1 = vec1.begin(); Iter1 != vec1.end(); Iter1++)
cout<<*Iter1<<" ";
cout<<endl;
return 0;
}
Output examples:
The original vec1 vector data is: 10 11 12 13 14 15 16 17 18 19 20
The copy vec2 vector data of the reversed vec1 vector is: 20 19 18 17 16 15 14 13 12 11 10
The original vec1 vector unmodified as: 10 11 12 13 14 15 16 17 18 19 20
