How to Reverse an Array in C++ ?

Answer

To reverse an array in C++, you can use the standard library function std::reverse from the header.

✐ Examples

1 Reverse Array of Integers

In this example,

We have an array named intArray containing integers.
We include the header to use the std::reverse function.
We call std::reverse on the range of elements in intArray to reverse the array.
We print the reversed array to demonstrate the reversal.

C++ Program

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    std::vector<int> intArray = {1, 2, 3, 4, 5};
    std::reverse(intArray.begin(), intArray.end());
    std::cout << "Reversed Array: ";
    for (int num : intArray) {
        std::cout << num << " ";
    }
    return 0;
}

Output

Reversed Array: 5 4 3 2 1

2 Reverse Array of Strings

In this example,

We have an array named strArray containing strings.
We include the header to use the std::reverse function.
We call std::reverse on the range of elements in strArray to reverse the array.
We print the reversed array to demonstrate the reversal.

C++ Program

#include <iostream>
#include <algorithm>
#include <vector>
#include <string>

int main() {
    std::vector<std::string> strArray = {"apple", "banana", "cherry"};
    std::reverse(strArray.begin(), strArray.end());
    std::cout << "Reversed Array: ";
    for (const std::string& str : strArray) {
        std::cout << str << " ";
    }
    return 0;
}

Output

Reversed Array: cherry banana apple
