How to Use std::sort to Order an Array in C ?

Sorting Arrays with std::sort in C

Question: How can I use the C standard template library's std::sort() to arrange an array in ascending order?

<code class="cpp">int v[2000];</code>

Answer: In C 11, you can utilize two convenient functions:

<code class="cpp">std::sort(std::begin(v), std::end(v));</code>

Additional Question: Does C have a way to determine the start and end positions of an array?

Answer: Yes, in C 11, std::begin and std::end are overloaded for arrays.

<code class="cpp">std::sort(std::begin(v), std::end(v));</code>

If you're using an earlier version of C , you can create your own versions of begin and end:

Non-const:

<code class="cpp">template<class Cont>
typename Cont::iterator begin(Cont&amp; c){
  return c.begin();
}

template<class Cont>
typename Cont::iterator end(Cont&amp; c){
  return c.end();
}</code>

Const:

<code class="cpp">template<class Cont>
typename Cont::const_iterator begin(Cont const&amp; c){
  return c.begin();
}

template<class Cont>
typename Cont::const_iterator end(Cont const&amp; c){
  return c.end();
}</code>

Overloads for C-style arrays:

<code class="cpp">template<class T, std::size_t N>
T* begin(T (&amp;arr)[N]){
  return &amp;arr[0];
}

template<class T, std::size_t N>
T* end(T (&amp;arr)[N]){
  return arr + N;
}</code>
