写出以下程序的执行结果。#include "stdio.h" void f13(int y,int *x) { y=y+*x; *x=*x+y; } int main() { int x=2,y=4; f13(y,x); printf("%d,%dn",x,y); return 0; }
写出以下程序的执行结果。#include "stdio.h" void f13(int y,int *x) { y=y+*x; *x=*x+y; } int main() { int x=2,y=4; f13(y,&x); printf("%d,%dn",x,y); return 0; }
参考答案和解析
B B。【解析】由主函数入手,定义了类TestClass的对象s1(2,3),当类对象进入其作用域时调用构造函数,构造函数应该是调用具有参数的“TestClass(inta,intb){x=a;y=b;}”,然后调用成员函数disp,则输出为“cout$amp;
