sorting vector

[oLC9216C]

Hi, I want to sort a vector<string> list alphabetically.
How can I do that?

for example I have a vector<string> with:
apple
alike
add
cat
blue
red
lion

how can I make it become

add
alike
apple
blue
cat
lion
red

The string value is only a word not a sentence.

The simplest way is to use std::sort() from the algorithm library.

http://www.cplusplus.com/reference/algorithm/sort/

#include <algorithm>

// ...

std::vector<std::string> vs; // assume it contains words

// ...

std::sort(vs.begin(), vs.end());

You shouldn't name your vector as "list" because there might be confusion between that and std::list, which is another container just like std::vector.

If you want to do the sorting yourself, read more here:

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

using namespace std;

int main()
{
    vector<string> vs;
    vs.push_back("apple");
    vs.push_back("alike");
    vs.push_back("add");
    vs.push_back("cat");
    vs.push_back("blue");
    vs.push_back("red");
    vs.push_back("lion");

    for (vector<string>::iterator it = vs.begin() ; it != vs.end(); ++it)
        cout << ' ' << *it;
    
    sort(vs.begin(),vs.end());
    
    cout << "\n";
    
     for (vector<string>::iterator it = vs.begin() ; it != vs.end(); ++it)
        cout << ' ' << *it;
    
    
   
   return 0;
