C++ List sort() Usage and Example

C++ List (List)

C ++ The List sort() function arranges the elements of the given list in ascending order. It does not involve any construction or destruction of elements. Elements are only moved within the container.

Syntax

void sort();

Parameters

It does not contain any parameters.

Return value

It does not return any value.

Example1

Let's look at a simple example

Example

#include iostream>
#include<list>
using namespace std;
int main()
{
　　　list<int> li={6,4,10,2,4,1};
　　　list<int>::iterator itr;
　　　cout << "The elements of the list are:";
　　　for(itr=li.begin();itr!=li.end();++itr)
　　　std::cout <<　*itr << ",",
　　　li.sort();
　　　cout << '\n';
　　　cout << "The sorted elements are:";
　　　for(itr=li.begin();itr!=li.end();++itr)
　　　std::cout <<　*itr << ",",
　　　　return 0;
}

Output:

The elements of the list are:　6,4,10,2,4,1,
The sorted elements are:　1,2,4,4,6,10

In this example, the sort() function sorts the elements of the given list, and its output is1,2,4,4,6,10.

Example2

Let's look at a simple example

Example

#include iostream>
#include<list>
using namespace std;
int main()
{
　　　list<char> li={'n','h','o','o','o'};
　　　list<char>:: iterator itr;
　　　for(itr=li.begin();itr!=li.end();++itr)
　　　std::cout <<　*itr;
　　　li.sort();
　　　cout << '\n';
　　　for(itr=li.begin();itr!=li.end();++itr)
　　　std::cout <<　*itr;
　　　　return 0;
}

Output:

w3codebox
hnooo

In this example, the sort() function sorts the characters based on their ASCII values.
