The default parameter passing mechanism in most programming languages, including C and C++, is "Call by Value".

Here's a step by step explanation:

1. Call by Value: In this method, the value of each of the actual parameters (arguments) in the calling function is copied into corresponding formal parameters of the called function. In this case, changes made to the parameter inside the function have no effect on the argument.

2. Call by Reference: In this method, a reference to the actual parameter (not the value) is passed to the function. This means that changes made to the parameter affect the passed argument.

3. Call by Value Result: This is a hybrid of call by value and call by reference. The method is mostly as if a call by value is performed, but before the called function finishes execution, the final values of the formal parameters are copied back into the actual parameters.

In most languages, the default is Call by Value, unless specified otherwise. However, it's important to note that this can vary depending on the programming language. For example, in Java, primitive types are passed by value, while objects are passed by reference.
