Passing information from calling function (Method) to the called function (method) is known as argument passing, by using argument passing, we can share information from one scope to another in C++ programming
There are two ways to pass an object into as a function argument: Pass-by-Value and Pass-by-Reference. They follow same rules as the assignment statement. 1. Pass-by-Value - The function argument variable is declared as pass-by-value, which works like an assignment statement assigning the...
In this example, the ModifyValue method takes an int parameter by reference using the ref keyword. When you call this method in the Main method, you're passing the number variable by reference. As a result, the value of a number is modified within the ModifyValue method, and the change ...

an in-process automation server (a dynamic-link library (DLL)) and you pass an argument ByRef, this is very efficient since no marshalling is done. The server is using the same array in memory as the client. This is possible since the server runs in the same address space as the ...
Consider what happens when the argument isn't a temporary: string local_str; Widget widget(local_str); In this case, both versions of the code make a copy of the string, but the second version also moves the string. That, again, is a cheap constant-time operation, whereas copying is ...

Strings as Function InputsThe most efficient and secure way to use a CString object in called functions is to pass a CString object to the function. Despite the name, a CString object doesn't store a string internally as a C-style string that has a NULL terminator. Instead, a CString ...
