How to Create a Static Class-like Behavior in C ?

Creating a Static Class in C

C does not natively support static classes like C#, where classes can be marked as static to prevent their instantiation. However, it is possible to achieve a similar effect by creating a class with all static methods.

Implementation

To create a C class with all static methods:

1. Define a class with the public access specifier.
2. Declare all methods inside the class as static.
3. Make the constructor private or delete it to prevent class instantiation.

Example

Consider the following BitParser class:

<code class="cpp">// BitParser.h
class BitParser
{
public:
  static bool getBitAt(int buffer, int bitIndex);
};</code>

<code class="cpp">// BitParser.cpp
bool BitParser::getBitAt(int buffer, int bitIndex)
{
  // Code to determine if the bit is set
}</code>

Usage

You can use this class to access its static methods without creating an instance:

<code class="cpp">cout << "bit 5 is " << BitParser::getBitAt(buffer, 5) << endl;</code>

Note:

This approach effectively emulates a static class by ensuring that no instances of the class can be created, and all its functionality is accessible through its static methods.
