How to call public functions

Different programming languages ​​call public functions differently: Python: Use import and . Symbol C: Use #include and namespace/class name Java: Use import and class name Other languages: Check out language-specific documentation

How to call a public function

Different programming languages ​​call common functions differently. The following are the calling methods in several common languages:

Python

In Python, you can use the import statement to import the module and then use the dot ( . ) operator to call the common function therein. For example:

 <code class="python">import math print(math.sin(1.5)) # 输出: 0.9974949871005295</code>

C

In C, you can use the #include preprocessing directive to include the header file and then use the namespace or class name to call the public function. For example:

 <code class="cpp">#include <iostream> using namespace std; int main() { cout </iostream></code>

Java

In Java, you can use the import statement to import the package and then use the class name to call the public function. For example:

 <code class="java">import java.util.Arrays; int[] array = {1, 2, 3, 4, 5}; Arrays.sort(array); // 对array进行排序</code>

Other languages

In other languages, the method of calling a public function may vary. Please consult the documentation for specific languages ​​for more information.

Advantages of Using Public Functions

• Code reuse: Public functions allow reuse of code in multiple programs, thereby improving development efficiency and reducing duplicate work.
• Modularity: Public functions organize the code into modular units, making the code easier to maintain and understand.
• Standardization: Public functions provide a consistent way to perform common tasks, ensuring the reliability and robustness of the code.
