# valarray min() in C++

• Last Updated : 23 Jun, 2020

The min() function is defined in valarray header file. This function returns the smallest value contained in the valarray.

Syntax:

`T min() const;`

Returns: This function returns the minimum value in the valarray.

Below programs illustrate the above function:

Example 1:-

 `// C++ program to demonstrate``// example of min() function.`` ` `#include ``using` `namespace` `std;`` ` `int` `main()``{``    ``// Initializing valarray``    ``valarray<``int``> varr = { 3, 2, 1, 4, 5 };`` ` `    ``// Displaying minimum element of valarray``    ``cout << ``"The smallest element"``         ``<< ``" of valarray is = "``         ``<< varr.min() << endl;`` ` `    ``return` `0;``}`
Output:
```The smallest element of valarray is = 1
```

Example 2:-

 `// C++ program to demonstrate``// example of min() function.`` ` `#include ``using` `namespace` `std;`` ` `int` `main()``{``    ``// Initializing valarray``    ``valarray<``int``> varr = { 22, 24, 36, 42, 12 };`` ` `    ``// Displaying minimum element of valarray``    ``cout << ``"The smallest element "``         ``<< ``"of valarray is = "``         ``<< varr.min() << endl;`` ` `    ``return` `0;``}`
Output:
```The smallest element of valarray is = 12
```
