argument is a action verb
An invalid argument is when the facts you are using are invalid or your forms of defense are wrong or incorrect, a valid argument is the opposite of an invalid argument. "There is a windmill in my beard. your argument is invalid." (This is a good example of a bad contradiction)
An argumentum is a formal term for an argument.
Formal fallacies are errors in the structure of an argument, while informal fallacies are errors in the content or reasoning of an argument.
C++ doesn't have parameters it has arguments, both formal and actual. Actual arguments are the arguments you pass to a function. Formal arguments are the arguments used by the function and which are treated as local variables within the function body. Formal arguments always fall from scope when the function returns. In order for a function to make changes to the actual argument you you can either return the formal argument by value and assign the function to the actual argument upon return, or you can pass the argument by reference. In the former case, the returned value is temporary. If the function is not assigned to the actual argument, the temporary value falls from scope. In the latter case, the actual and formal arguments both refer to the same object through separate names (aliases). Thus any operations performed on the formal argument will affect the actual argument (they are one and the same object). Example: // Forward declarations. int byval (int); void byref (int&); int main() { int actual = 42; byval (actual); // The byval formal argument is no longer in scope. // Although a temporary value of 84 was returned, // it wasn't assigned to anything and is no longer // available. // The actual argument still has the value 42. actual = byval (actual); // The byval formal argument is no longer in scope, // however, its value was returned and assigned // to the actual argument. // The actual argument now has the value 84. byref (actual); // The formal argument and the actual argument are // one and the same argument. // The actual argument now has the value 42. } int byvalue(int formal) { formal *= 2; return formal; } // The formal argument no longer exists, but its value // was pushed into the function's return address. That // value will cease to exist unless the caller immediately // assigns the function's return value to a variable. void byref(int& formal) { formal /= 2; } // The formal argument no longer exists and nothing // was pushed onto the function's return address. // However, formal was just an alias for the actual // argument, thus the actual argument has already // been updated.

A formal fallacy is a mistake in the logical structure of an argument, while an informal fallacy is an error in the content or context of the argument.
A formal logic proof solver can be used to determine the validity of a logical argument by systematically applying rules of logic to the argument's premises and conclusions. The solver checks if the argument follows a valid logical structure, ensuring that the conclusions logically follow from the premises. If the proof solver successfully demonstrates that the argument is valid, it provides a formal verification of the argument's soundness.
A formal debate is an argument between two individuals that is bound by rules and the participants conduct themselves professionally. Some formal debates are competitions that are judged to have a winner.
In C++ there is no such thing as a parameter, there are only arguments, both actual and formal. Some languages use the term parameter to mean a formal argument and argument to mean an actual argument, while others reverse the meanings completely. Some languages make no distinction at all and use the terms parameter and argument interchangeably. However, C++ is quite clear on this: actual arguments are the names that you pass to a function, while formal arguments are the names received by the function. Even so, you will still encounter incorrect usage of the terms parameter and arguments, even by C++ experts (myself included!) The following example code demonstrates the difference between an actual argument and a formal argument, as the terms apply in C++: int foo(int formal) { return(formal*2); } void bar(int& formal) { formal*=2; } int main() { int actual=1; actual = foo(actual); bar(actual); return(0); } The function foo() declares a formal argument by value while bar() declares a formal argument by reference. In main() we declare a variable with the name actual and pass this actual argument to both functions in turn. When we pass actual to foo(), the value of actual is assigned to formal. Since formal is a copy of actual, they are separate names with separate values (initially they will have the same value of course). Thus any changes made to formal will have no effect on actual, hence we must assign the return value from foo() to actual in main(), in order to record the change made by foo(). When we pass actual to bar(), a reference to actual is assigned to formal. A reference is simply an alternate name for the same argument, however the name actual is not visible to bar(), so they are still separate names, but they always have the same value. Thus any changes to formal will affect actual, thus there is no need to assign any return value to record the change.
A formal fallacy in logic occurs when the structure of an argument is flawed, leading to an invalid conclusion. An informal fallacy, on the other hand, involves errors in reasoning or the content of the argument, making it unsound.
Anecdotal argument is more intimate and less formal compared to logical or empirical argument. It relies on personal experiences, stories, or examples to make a point, connecting with the audience on a more emotional level. It is often used in casual conversations or personal narratives.
In programming languages, a parameter and an argument are the same thing; there is no actual difference between the two. Although a few languages do differentiate between an actual argument and a formal argument by calling one a parameter and the other an argument (or vice versa), the terms are universally interchangeable. That is; there is no single definition that applies to any one language, including Visual Basic. The language may have a convention, but there's no reason to follow that convention. Personally, I prefer the term argument and use the terms formal argument and actual argument whenever I need to specifically differentiate one from the other. In this way I can refer to them in a consistent but language-agnostic manner. Only a Pedant would argue that the terms parameter and argument have a specific meaning to a specific language, even when the creators of that language use the terms interchangeably themselves. To clarify, an actual argument is the argument being passed to a function while a formal argument is the argument that is used by the function. The two will always have the same value, but they are not the same argument. For instance, consider the following function definition: f (int a) { print a*2 } Whether we regard 'a' as being a parameter or an argument is immaterial -- it is a formal argument or formal parameter, whichever you prefer. The meaning is clarified by using the word "formal". Now consider the calling code: b = 42 f (b) Here, b is the actual argument (or actual parameter) being passed to the function f. Note that a and b are not the same variable or reference. That alone means there is no reason to differentiate them; the meaning of argument or parameter is implied by the context alone. It doesn't matter whether the function uses pass by value or pass by reference semantics. When passing arguments by value, a is simply a copy of b (independent variables with the same value). When passing by reference, a refers to the same memory address as b (a is an alias for b). In either case, the function uses the formal argument named a while the calling code uses the actual argument named b. In other words, the names are only accessible from within the scope in which they are declared, even if they refer to the same memory address. Of course, a function may pass one of its formal arguments to another function. Thus with respect to the calling function, its formal argument becomes an actual argument to the function being called.
When we invoke a function, we pass the actual arguments in the same order specified by the function's formal arguments, thus it is the relative position that determines how they are matched. Note that actual parameter names are within the scope of the calling code while formal parameter names are scoped to the function in which they are declared. The calling code has no access to the formal argument names, and the function may or may not have access to the actual argument names. Python uses the pass-by-object paradigm: if the object being passed is immutable, then it is passed by value (the formal parameter is assigned a copy of the object's value), otherwise it is passed by reference (in which case the formal argument becomes an alternative name for the actual argument).
