Sorting the characters in a string in C++

Sorting of characters is too easy with this function in C++.

#include <iostream>
using namespace std;

int main () 
{
    string str = "Shirley";

    // It sorts the characters and stores in the same string.
    // Sorting happens based on the ASCII value.
    sort(str.begin(), str.end());
    cout << str << endl;

    return 1;
}

Output:

Sehilry

Takeaways :

• It sorts the characters and stores it in the same string. 
• Sorting happens based on the ASCII values.

I also wanted to show you that we can copy a string to character.

#include <iostream>
#include <sstream>
#include <cstring>
using namespace std;

int main()
{ 
    stringstream line("I often post some programming contents");
    string word = "";
    char arr[1] = {'\0'};
    int count = 0;
    
    while (getline(line, word, ' ')) {
        count++;
        cout << word << endl;
        if (count == 1) {
            strcpy(arr, word.c_str());
            cout << " First word is " << arr << endl;
        }
        
    }

    return 0;
}

Output

I
 First word is I
