C++引用作为参数传递

void swap1(int& x, int& y){ int temp; temp = y; y = x; x = temp; } C++引用作为参数传递，直接传入地址，不再开辟新的复制空间，c语言中没有 int main() { int x, y; x = 10, y = 103; // swap(&x, &y); // swap1(x,y); cout<<"*x: "<<x<<"*y: "<<y<<endl; cout << "Hello world!" << endl; return 0; }

C语言 

void swap(int* x, int* y){ int temp; temp = *y; *y = *x; *x = temp; } int main() { int x, y; x = 10, y = 103; swap(&x, &y);//一个int变量，加上了取地址符号就变成了指针 cout<<"*x: "<<x<<"*y: "<<y<<endl; cout << "Hello world!" << endl; return 0; }

指针数组数组指针到底是什么东西

 

卧槽，可以直接以数组的形式传递
