include include <stdio.h> 大哥，程序没问题。就是输出格式错了， printf("the program consumes: \n%d",totaltime);改成 printf("the program consumes: \n%lf",totaltime);浮点数，你用十进制输出了。另外，要记得在程序开始，或者其它地方初始化start：start =clock();我调了半天。。。
这一段代码在本菜鸟看来,貌似人畜无害,只是把谓词函数cmp写成了类内函数(之前曾讲cmp写成全局函数,在main中类似调用,没碰到过问题),谁知编译竟报出: error: invalid use of non-static member function ‘bool MyClass::cmp(int, int)’ 看报错信息的字面意思似乎是:因为cmp是非static函数,那如果把cmp定义成...

MicRecorder.cpp:297:79: error: invalid use of non-static member function。 1 2 如果要创建线程函数audioThread为MicRecorderImpl类成员函数,就需要使用静态函数。 但是,使用静态函数有两个问题: 1.静态函数不能访问非静态成员; 2.无法实现多实例;
class Date { public: int day,month,year; void init(int,int,int); void print_ymd(); }; void Date::init(int yy, int mm, int dd) { year = yy; month = mm; day = dd; } void Date::print_ymd() { std::cout << year << "-" << month << "-" << day << std::endl; ...
项目中使用std::thread把类的成员函数作为线程函数,在编译的时候报错了:"invalid use of non-static member function",于是研究了一番,于是就产生了这篇博文,记录一下。 错误示例 #include <iostream> #include <thread> ...
I'm having a bad time trying to call a correctly-working expression (ultra[currentSensor].ping_timer(echoCheck)) from an own class method (myclass::run) instead of from void loop(). I'm getting the following compiler error: "invalid use of non-static member functi...
