Function prototype A function prototype is simply the declaration of a function that specifies function's name, parameters and return type. It doesn't contain function body. A function prototype gives information to the compiler that the function may later be used in the program. Syntax of functi...
在 cppreference 中搜索 prototype，发现都是 C 中的词条会用到 prototype 这个词。函数原型（prototype...
在C#和Java中,都已經取消了這兩種機制,老實說,function prototype的確可以由compiler代勞,只要compiler在compile前,預先蒐集所有的function,然後自行產生function prototype即可,這樣連header file也可省了,不過header file另外一個附屬功能:『註解文件』,雖然在Java有Javadoc,C#有XML Comment可另外產生文件檔,但我個人認為...
It is now considered good form to usefunction prototypesfor all functions in your program. A prototype declares the function name, its parameters, and its return type to the rest of the program prior to the function's actual declaration. To understand why function prototypes are useful, enter ...
What is memcpy()memcpy() is a standard function used in the C programming language to copy blocks of memory from one place to another. Its prototype is defined in the string.h header file as follows:void *memcpy(void *dest, const void *src, size_t n); ...
Function prototype in C is used by the compiler to ensure whether the function call matches the return type and the correct number of arguments or parameters with its data type of the called function. In the absence of the function prototype, ...

The same applies to functions. Functions cannot be called before they are declared. That is why, in all the previous examples of functions, the functions were always defined before themainfunction, which is the function from where the other functions were called. Ifmainwere defined before the ...
