- A ______ circuit is one in which the current flows in a single continous path and is of the same value at every point in circuit
- If _____ voltage is applied across _____ circuit, _____ electric current will flow in _____ circuit.
- The function of direct current regulated power supply is to input an alternating current power of 220volts, so that it can output __________.( ) A: alternating current 200 volts voltage B: direct current 24 volts voltage C: direct current 200 volts voltage D: alternating current 24 volts voltage
- 有以下程序： #include ＜iostream＞ #include ＜cmath＞ using namespace std； class Distance； class point { public： friend class Distance； Point(int a，int B) { x=a； Y=b； } void Print() { cout＜＜"X= "＜＜X＜＜end1； cout＜＜"Y= "＜＜Y＜＜end1； } private： float X，Y； }； class Distance { public： float Dis(Point &p，Point &q)； }； float Distance :: Dis(Point &p，Point &q) { float result； result=sqrt((p.X-q.X)*(p.X-q.X)+(p.Y-q.Y)*(p.Y-q.Y))； cout＜＜result＜＜end1； retUrn result； } int main() { Point p(10，10)，q(10，30)； Distance d； d．Dis(p，q)； return 0； } 运行后的输出结果是( )。 A: 10 B: 30 C: 0 D: 20
