Building a prototype allows the designer to explore unforeseen problem areas before building the finished product. Prototypes can also be used for testing to see how a device will operate in real-world conditions as opposed to computer projections, and to determine production cost and propose a budget.
A function prototype is a function declaration that specifies the data types of its arguments in the parameter list.
That is, it decides what the function can return. The compiler uses this prototype to find out what kind of data it can return.
you can see the attached link for further information.
Prototypes are made to test the design, see if it's good enough, check that it works as intended and so on. Then, when they know that the design is good enough, they go to series production.
It'd be a big waste of money if they built a lot of units, and then discovers that they aren't working as intended.
Function prototypes are declarations of functions. A prototype does not require a definition at the point of use, the declaration alone tells the compiler the function's type, name and its argument types. Function prototypes are typically declared in header files so that the same function can be used in more than one translation unit, while the definition can be placed in any translation unit. Function definitions must adhere to the one-definition rule.
Function declarations or prototypes are often called function interfaces while the function definition provides the implementation of that interface. It is a good idea to keep interfaces and implementations separate, as the interface should provide everything a caller needs to know about the function, with user-comments providing any additional information required by the caller. The implementation details are of little relevance to the caller and can actually become a distraction, making code that much harder to read.
In C, all user-defined identifiers must be declared to the compiler before they can be used. This includes functions. A prototype is simply another name for a declaration. A function's definition is itself a declaration, however the compiler only needs to see the declaration. To ensure that all function declarations remain consistent across all translation units that require them, we place those declarations in header files such that each header file represents a group of related functions and/or types. We simply include those headers wherever they are needed. The function definitions are typically placed in the corresponding translation unit source file, however trivial implementations are often defined in the header thus making the definitions visible to the compiler and thereby giving greater opportunities for inline expansion.
Prototyping is an experimental process where design teams implement ideas into tangible forms from paper to digital. Teams build prototypes of varying degrees of fidelity to capture design concepts and test on users. With prototypes, you can refine and validate your designs so your brand can release the right products.
Normally, a designer will go into three steps before the handoff.
1. Wireframe;
2. Mockup;
3. Prototype.
When prototypes are made. Developers will translate those prototypes into code and present them in a visually acceptable manner. If you want to learn prototyping, you need to find a suitable tool. Here is one for you!
Mockplus - Connect your entire product design workflow
As a brand-new collaboration tool for designers and developers, it goes far beyond design and workflow—allowing mobile designers to create masterpieces. It allows you to upload your wireframes and visual designs from Photoshop, AdobeXD, and Sketch, and add them to your project folder.
A full set of features about prototyping, commenting, collaborating and design handoff enable you to create a product from the start to finish.
To know if your design works in `real world' applications. The to troubleshoot any problems, correct them and derive a final design.
Prototype of a function can be understood as the set of rules, that act as guideline for the rest of function.Prototype defines the function the function ,without it the function won't work.
Prototyping allows a rudimentary version of the final software to prove that the design is viable before too much effort is put into coding a flawed design.
when we write definition of a function i.e; body of a function above main() function, then the function prototype be omitted. -Ramashankar Nayak,M.C.A,Pondicherry University
Syntax errors and prototype errors.
A prototype in C is the declaration of a function. Without a prototype, the function cannot be called because the compiler would have no way of knowing if the function was being called correctly. Prototypes may appear in multiple translation units but can only be defined once. A definition is itself a prototype.
Your question makes no sense.
Yes. Examples can be found in stdio.h

yes
You can write a program without specifying its prototype when the function returns an integer.If the prototype is not mentioned the compiler thinks that the return type of the function used is integer.When making program which return integer you can ignore writing the protoype.
Your question makes no sense.
Prototype of function describes return value as well as which data can be passed to the function.
It means that the function doesn't have parameters.example:int foo (void); -- it is a prototype for function 'foo', having no parametersint bar (); -- it is not a prototype as it says nothing about the parameters
A function prototype is the first line of a function which depicts its access specifier, modifier ,return type and name along with the number and type of arguments in it.. example: public static void zoom(int a,String b)
Yes. Examples can be found in stdio.h
In C, a function prototype is a declaration to the compiler that a certain function exists, without a full definition. This allows other functions to call that function. The linker will later make sure that a function definition actually exists (perhaps somewhere else), and will turn the call to the function to a call to the correct function.
