How to sort a Vector in descending order using STL in C++?

• Last Updated : 19 Mar, 2019

Given a vector, sort this vector in descending order using STL in C++.

Example:

```Input: vec = {1, 45, 54, 71, 76, 12}
Output: {76, 71, 54, 45, 12, 1}

Input: vec = {1, 7, 5, 4, 6, 12}
Output: {12, 7, 6, 5, 4, 1}
```

Approach: Sorting can be done with the help of sort() function provided in STL.

Syntax:

```sort(arr, arr + n, greater<T>());
```
 `// C++ program to sort Vector``// in descending order``// using sort() in STL`` ` `#include ``using` `namespace` `std;`` ` `int` `main()``{``    ``// Get the vector``    ``vector<``int``> a = { 1, 45, 54, 71, 76, 12 };`` ` `    ``// Print the vector``    ``cout << ``"Vector: "``;``    ``for` `(``int` `i = 0; i < a.size(); i++)``        ``cout << a[i] << ``" "``;``    ``cout << endl;`` ` `    ``// Sort the vector in descending order``    ``sort(a.begin(), a.end(), greater<``int``>());`` ` `    ``// Print the reversed vector``    ``cout << ``"Sorted Vector in descendiing order:n"``;``    ``for` `(``int` `i = 0; i < a.size(); i++)``        ``cout << a[i] << ``" "``;``    ``cout << endl;`` ` `    ``return` `0;``}`
Output:
```Vector: 1 45 54 71 76 12
Sorted Vector in descendiing order:
76 71 54 45 12 1
