看到面试题C语言中函数参数的入栈顺序如何? 自己不知道,边上网找资料.下面是详细解释 #include <stdio.h> void foo(int x, int y, int z){ printf("x = %d at [%X]/n", x, &x); printf("y = %d at [%X]/n", y, &y); printf("z = %d at [%X]/n",
一:函数补充 默认作为函数参数的数据,是浅拷贝传递.不是和C等语言一样,产生一个临时变量. class T: def __init__(self,num): print(id(num)) self.num = num print(id(self.num)) def printf(self): num = self.num print(id(num)) #数据没有被改变过,所以这里的所有相关num变量都是指向同一个内存空间 if __name__ == "__main__": num =

class Program { private static void Fun(int x, int n, Stack<int> stack, List<int> outList,ref int count) { if (outList.Count == n) { count++; Console.WriteLine(string.Join(',', outList)); } if (x <= n) { stack.Push(x); Fun(x + 1, n, stack,
C++编译器默认使用的是 __cdecl 模式,参数是通过栈传递的,因此是从右到左的传参顺序. int f(int a, int b, int c) { return 0; } int main(){ return f(printf("a"),printf("b"),printf("c")); } 当用函数做实参时,编译器一般会根据参数传递顺序,先计算出函数的返回值,然后将返回值传递给原来的函数. 函数的参数是通过栈传递的.因此参数从右往左入栈顺
