Use of the min() in C++

[Tailor]

Hello, I am the student of the MSC. I have the knowledge of the C++ language. I can also have the knowledge of the functions of the C++ language. I want to know about the min() function of the C++ language. So, I would like to know how can I use the min() function in the C++ language. Can you have the information on the min() function of the C++ language.

The following code of lines demonstrates you about the use of the min() function :

#include <iostream>
#include <algorithm>
using namespace std;
int main () 
{
  cout << "min(2,1)==" << min(2,1) << endl;
  cout << "min(1,2)==" << min(1,2) << endl;
  cout << "min(3.14,2.72)==" << min(3.14,2.72) << endl;
  cout << "min('a','z')==" << min('a','z') << endl;
  return 0;
}

Output:

min(2,1)==1
min(1,2)==1
min(3.14,2.72)==2.72
min('a','z')==a

Hello, According to my knowledge about the min() function that The min() function can be used for to find out the minimum character between the defined two values. The following can be the general syntax of the min() function :

template <class T> const T& min ( const T& a, const T& b );

There can be the one more program on the min() function as follows :

#define NOMINMAX
#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
    cout << min(3, 5) << endl;
}

Output :

3

The min() function of the C++ language can returns the minimum value among the two values that means it can returns the lesser of p and q. The min() function of the C++ language can uses the < operator to check the minimum value. The behavior of min() function template can be equivalent to the following :

template <class S> const S& min ( const S& p, const S& q ) 
{
  return (p<q)?p:q; 
}
