How to use min function in c++

The min() function in C returns the minimum of two or more values. It is a generic function that can compare values ​​of different types. Usage is as follows: Compare two values: min(a, b) Compare multiple values: min(a, b, c) Compare values ​​of different types: min(a, b, c) (need to specify the type explicitly) Applicable to Comparison of elements in arrays and containers

min() function in C

min() function is used Returns the minimum of two or more values. It is a generic function that can be used to compare values ​​of different types.

Syntax

<code class="cpp">template <typename T>
T min(T a, T b);
template <typename T>
T min(T a, T b, T c);
...</code>

Where, T is the type of the value to be compared.

Usage

• Compare two values:

<code class="cpp">int x = min(5, 10); // x = 5</code>

• Compare Multiple values:

<code class="cpp">int y = min(5, 10, 15); // y = 5</code>

• Comparing values ​​of different types:

<code class="cpp">double z = min(5.5, 10.0); // z = 5.5</code>

Note

• If the types of objects to be compared are different, you need to specify the type explicitly, otherwise a compilation error will occur.
• If the object to be compared is a string, you can use the std::string::compare() function.
• The min() function can also be used to compare elements in arrays and containers.
