reverse integer cpp code example
Example 1: reversing numbers in C++
#include <iostream>
#include <string>
using namespace std;
int reverse(int number);
int main() {
int x = 18475;
cout << "18475 reversed is " << reverse(18475) << endl;
}
int reverse(int number) {
int result = 0;
while (number > 0) {
result = result * 10 + number % 10;
number /= 10;
}
return result;
}
Example 2: reverse() in c++
#include <iostream>
#include <algorithm>
#include <vector>
#include <iterator>
using namespace std;
int main()
{
vector<int>a = {11,22,33,44,99,55};
reverse(a.begin(), a.end());
auto it = a.begin();
for(it= a.begin(); it!=a.end(); it++){
cout << *it << ' ';
}
}
Example 3: reverse c++
reverse(str.begin(),str.end());
