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

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

Answer

To sort an array in ascending order in C++, you can use the `sort` function from the `algorithm` library for both arrays of integers and arrays of strings.

✐ Examples

1 Sort Array of Integers

In this example,

Create an array of integers, for example, numbers.
Use the sort function from the algorithm library to sort the array of integers in-place.
Print the sorted array to see the result.

C++ Program

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

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

Output

1 2 5 8 9

2 Sort Array of Strings

In this example,

Create a vector of strings, for example, words.
Use the sort function from the algorithm library to sort the vector of strings in-place based on string comparison.
Print the sorted vector to see the result.

C++ Program

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

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

Output

apple banana cherry date
