程序段N10 R1=30 R2=32 R3=50 R4=20;N20 G00 X=R2*SIN(R1)+R4 Z=R2*COS(R1)+R3;中,只对X坐标值有影响的R参数是()(SIEMENS系统)。
有以下程序:include using namespace std;class R{public: R(int f1,int r2) {R1=r1;有以下程序: #include <iostream> using namespace std; class R { public: R(int f1,int r2) { R1=r1; R2=r2; } void print(); void print ()const; private: int R1, R2; }; void R: :print() { cout<<R1<<", "<<R2<<end1; } void R: :print() const { cout<<Rl<<", "<<R2<<end1; } int main () { R a(5,4); const R b(20,52); b.print (); return 0; } 执行后的输出结果是A.5,4B.20,52C.0,0D.4,5
