How to Sort an Array in Descending Order in C++ - Step by Step Examples

How to Sort an Array in Descending Order in C++ ?

Answer

To sort an array in descending order in C++, you can use the `sort` function from the `` library with a custom comparison function.

✐ Examples

1 Sort Array of Integers in Descending Order

In this example,

Create a vector of integers, for example, numbers.
Define a custom comparison function that compares two integers in descending order.
Use the sort function to sort the vector of integers using the custom comparison function.
Print the sorted vector to see the result.

C++ Program

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

bool compare_desc(int a, int b) {
    return a > b;
}

int main() {
    std::vector<int> numbers = {5, 2, 8, 1, 9};
    std::sort(numbers.begin(), numbers.end(), compare_desc);
    for (int number : numbers) {
        std::cout << number << " ";
    }
    return 0;
}

Output

Sorted array in descending order: 9 8 5 2 1

2 Sort Array of Strings in Descending Order

In this example,

Create a vector of strings, for example, words.
Define a custom comparison function that compares two strings in descending order.
Use the sort function to sort the vector of strings using the custom comparison function.
Print the sorted vector to see the result.

C++ Program

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

bool compare_desc(const std::string& a, const std::string& b) {
    return a > b;
}

int main() {
    std::vector<std::string> words = {"apple", "banana", "cherry", "date"};
    std::sort(words.begin(), words.end(), compare_desc);
    for (const std::string& word : words) {
        std::cout << word << " ";
    }
    return 0;
}

Output

Sorted array in descending order: date cherry banana apple
