How to Simulate Static Classes in C ?

Accessing Static Methods in C

You may have noticed that in many programming languages, it is possible to declare a class as static. This allows you to access its methods without instantiating an object. In C , however, this concept is not directly supported.

The Solution

To simulate static class behavior in C , you can use a public static method within your class. This method can be accessed without creating an instance of the class. Consider the following example:

<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) {
  bool isBitSet = false;
  // Determine if bit is set
  return isBitSet;
}</code>

Usage

You can use this code to call the method in the following manner:

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

This code will execute without creating an instance of the BitParser class.

Note: All constructors within the class should be declared as private or = delete to prevent the creation of instances.
