Message Passing in C++

The act of sending and receiving information by an object is referred to as communication, and all communication between objects that takes place via message is known as message passing. In order for message passing to be possible, the following steps must be taken:

1. Classes must be developed to specify objects and their behaviors.
2. making the objects from class declarations after that
3. linking and calling the communication between objects

Only static message passing is supported by C++; Because they offer dynamic message forwarding, programming languages like Smalltalk and Objective-C are regarded as being more flexible than C++. when an object's method is called, the target object must also have that method; otherwise, the compiler generates an error.

When creating apps, developers frequently have to deal with multi-threading. We very likely need to synchronize many threads when working with them, and message passing is one of the synchronization techniques.

The message passing task's C++ code implementation is shown below:

class first
{
    public void Method_name(Object o)
    {
        // Method performs assigned tasks
    }
}
class second
{
    public void Method_name(Object o)
    {
        // Method performs assigned tasks
    }
}


class third
{
    Object o1 = new Object();
    first s = new first();
    s.Method_1(o1);
    Object o2 = new Object();
    second s2 = new second();
    s2.Method_1(o2);
    
}
