Pre-defined comes built in as a function. [=SUM(A1:A12]
User-generated is created by the user. [=A1+A2]
keywords are predefined words
Predefined functions are functions that have been written and we can use them in our C++ statements. But we must know how to use each of these predefined functions.
What is the difference between predefined function and user defined functions
A predefined structure or, more generally, a predefined type, is a type that is defined internally by the compiler implementation. For instance Microsoft's implementation includes predefined runtime information and GUID structures, amongst other predefined types such as size_t. These types are built in to the compiler itself, so you won't find them in a header file. By contrast, user-defined structures (types) are those you define yourself, or are provided for you by a third party.

You're paying for the brand name or not.
When you are using mathematical formulas, it is good to know the difference. For example finding the circumference or area of a circle.
oscillator is which oscillates to a required proportion in order to generate signal with required frequency. whereas, regulator limits the signal to a predefined value and offers a constant out put through out
the formulas for lateral area dont include the figures bases. surface area does.
A function is designed to do a specific kind of task, like the way the MAX function can only calculate the highest value in a range. Functions are predefined formulas that do tasks in a simpler way, saving the user time. A function normally has a standard process so it can be applied to any values that the user supplies. A formula can consist of functions and can do a wide range of things. A formula can be a particular function used to do a specific calculation. What-if analysis uses formulas or functions to enable you to work out what happens in similar situations using different values. The formulas stay the same and then different values can be used to experiment to see what happens in different situations.
