How to Sort Characters in String in C++ - Step by Step Examples

How to Sort Characters in String in C++ ?

Answer

In C++, you can sort characters in a string by converting the string to a vector of characters, sorting the vector, and then joining it back into a string.

✐ Examples

1 Sort Characters in Ascending Order

In this example,

We create a string named str.
We convert the string to a vector of characters.
We sort the vector of characters in ascending order.
We join the sorted vector of characters back into a string.
Finally, we print the sorted string in ascending order.

C++ Program

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

int main() {
    std::string str = "hello world";
    std::sort(str.begin(), str.end());
    std::cout << "Sorted string in ascending order: " << str << std::endl;
    return 0;
}

Output

Sorted string in ascending order:  dehllloorw

2 Sort Characters in Descending Order

In this example,

We create a string named str.
We convert the string to a vector of characters.
We sort the vector of characters in descending order.
We join the sorted vector of characters back into a string.
Finally, we print the sorted string in descending order.

C++ Program

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

int main() {
    std::string str = "hello world";
    std::sort(str.begin(), str.end(), std::greater<char>());
    std::cout << "Sorted string in descending order: " << str << std::endl;
    return 0;
}

Output

Sorted string in descending order: wroolllhed
