Sure:
int main (void) { puts ("Hello, world"); return 0; }
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.
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.
A function prototype is a declaration of a function that specifies its name, return type, and parameters without providing the actual body or implementation of the function. It serves as a way to inform the compiler about the function's existence and how it can be called. In languages like C and C++, prototypes are typically placed before the main function or in header files, allowing for proper type checking during compilation. This helps to ensure that the function is used correctly throughout the code.
This is not a question.
A function prototype is basically a definition for a function. It is structured in the same way that a normal function is structured, except instead of containing code, the prototype ends in a semicolon.Normally, the C compiler will make a single pass over each file you compile. If it encounters a call to a function that it has not yet been defined, the compiler has no idea what to do and throws an error. This can be solved in one of two ways.The first is to restructure your program so that all functions appear only before they are called in another function.The second solution is to write a function prototype at the beginning of the file. This will ensure that the C compiler reads and processes the function definition before there's a chance that the function will be called.For example, let's take a look at a few functions form a linked list implementation.// Sample structuresstruct linked_list_node {int data;struct linked_list_node *next;};struct linked_list {int size;struct linked_list_node *root;};// Function Prototypesvoid deleteLinkedList(struct linked_list *list);void deleteNodes(struct linked_list_node *node);// Actual functions:// deletes the given linked listvoid deleteLinkedList(struct linked_list *list) {if( list != NULL ) {// delete nodesdeleteNodes(list->root);// lose the pointerlist->root = NULL;// delete actual listfree(list);}}// deletes all nodes starting at nodevoid deleteNodes(struct linked_list_node *node) {if( node != NULL ) {// deallocate next, if it existsif( node->next != NULL ) {deleteNodes(node->next);// lose the pointernode->next = NULL;}// deallocate nodefree(node);}}
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.

Prototypes may appear in multiple translation units but can only be defined once. A definition is itself a prototype.
In C programming, a function prototype declares the function's name, return type, and parameters before its actual definition, allowing the compiler to understand how to call the function. When it is said that "printf should have a prototype," it means that the function should have a declaration that informs the compiler about its signature, typically included via the <stdio.h> header file. This ensures proper type checking and helps avoid errors during compilation when the function is used. Without a prototype, the compiler may not know how to handle the function call correctly.

No, you cannot patent an idea without a prototype. A prototype is typically required to demonstrate the functionality and feasibility of the idea in order to obtain a patent.
It is not possible. In C, any program must have at least one function to be able to compile and execute properly: the function main()
C programs do not function without functions.
It can be done via its address, for example: void function (void (*callback)(void)) { (*callback)(); }
This is not a question.
not possible dude
