本程序关键点在于函数的声明,在这里函数声明不能省略,如果第三第四行的函数声明:void add(int x,int y) 和void add2(float x,float y)
省略了,则在接下来定义的函数add里面的调用add2:[add2(x,y) ]会提示出错,因为没有声明的情况下,系统不知道调用的add2或者本身的add是
什么意思-The key points of the program lies in the function declaration, function declaration can not be omitted here, if the third and fourth lines of the function declaration: void add (int x, int y) void add2 (float x, float y) omitted add inside the functions defined in the next call add2: [add2 (x, y) ] will prompt an error, because of the declaration, the system does not know call add2 or the add what
