所以It is always recommended to declare a function before its use so that we don’t see any surprises when the program is run (Seethisfor more details).
As aparameter to a function: int my_function(returnType(*parameterName)(parameterTypes)); (example code) As areturn value from a function: returnType(*my_function(int, ...))(parameterTypes); (example code) As acast(but try not to cast functions): ...
As aparameter to a function: int my_function(returnType(*parameterName)(parameterTypes)); (example code) As areturn value from a function: returnType(*my_function(int, ...))(parameterTypes); (example code) As acast(but try not to cast functions): ...
As long as you declare functions first, it is also possible to use functions to call other functions: Example Use one function to call another function: // Declare two functions, myFunction and myOtherFunction voidmyFunction(); voidmyOtherFunction(); ...
returnType (*variableName)(parameterTypes) = function_name; (example code) As a static const variable: static returnType (* const variableName)(parameterTypes) = function_name; (example code) As an array: returnType (*arrayName[])(parameterTypes) = {function_name0, ...}; (example code...
// declare a function called drawLine; don't mangle// its nameextern "C"void drawLine(int x1, int y1, int x2, int y2);不要以为有一个extern 'C',那么就应该同样有一个extern 'Pascal'和extern 'FORTRAN'。没有,至少在C++标准中没有。不要将extern 'C'看作是申明这个函数是用C语言写的,...
