Reverse an array in C++
The article showcase an array to be reversed in descending order using the C++ coding wherein the highest index is swapped to lowest index consequently by traversing the array in the loop.
Example
#include <iostream>
#include <algorithm>
using namespace std;
void reverseArray(int arr[], int n){
for (int low = 0, high = n - 1; low < high; low++, high--){
swap(arr[low], arr[high]);
}
for (int i = 0; i < n; i++){
cout << arr[i] << " ";
}
}
int main(){
int arrInput[] = { 11, 12, 13, 14, 15 };
cout<<endl<<"Array::";
for (int i = 0; i < 5; i++){
cout << arrInput[i] << " ";
}
int n = sizeof(arrInput)/sizeof(arrInput[0]);
cout<<endl<<"Reversed::";
reverseArray(arrInput, n);
return 0;
}Output
As the integer type of array supplied in a bid to be reversed in descending order, the following yields as ;
Array::11 12 13 14 15 Reversed::15 14 13 12 11
