写出下面程序运行时单击窗体的输出结果。
Private Sub f(a%, b%)
a = a + b
b = a - b
End Sub
Private Sub Form_Click()
Dim a%, b%
a = 23
b = 12
Call f(a, b)
Print "a=" & a; ",b=" & b
End Sub
阅读下面程序,写出输出结果。
#include using namespace std ; class A { int a, b; public : A() { a = b = 0; }
A(int aa, int bb) { a = aa; b = bb; cout << a << ' ' << b << endl ; } }; int main() { A x, y(2,3);
return 0; }
