Call By Address 與 Call By Reference In C++

#include

using namespace std;

void something(int *b)

{

*b += 100;

return;

}

void some2(int &b)

{

b+=100;

}

int main()

{

int a = 5;

int *x=&a;

cout << (*x) << endl;

something(x); // b 指到 x 且x指到a的記憶體位址

cout<<*x<

something(&a); // b 指到 a 的記憶體位置;

cout << a << endl; //call by address

some2(a); // int &b = a; 與 call by address 差別在於一個需要每次都打&

cout <

system("pause");
