错误描述: 今天在使用Qt写一个C++函数模板的测试程序的时候,编译的时候,编译的时候出现如下错误: 错误描述为:在main函数中,进行函数max()重载时,出现(ambiguous)含糊的,不明确的;引起歧义的使用; 因为第一次遇到这种错误,写篇内容纪念一下吧. 测试代码如下: #include <iostream> using namespace std; template <typename T>//typename == class T max(T a,T b) { ret
--max(字段名)中的"字段名"的数据类型是字符型的,"字段名"+ 0后,oracle会隐式的转换成数字型 --测试 )); insert into Test(a) ' from dual union all ' from dual union all ' from dual union all ' from dual union all ' from dual; select * from Test; select max(a) from Test; ) fro

base.h处于core模块中,是OpenCV的核心类.其作用是定义了OpenCV的基本错误类型,在程序运行出现错误是抛出错误,防止数据溢出.总而言之,其功能主要是考虑程序的健壮性. 头文件 #ifndef __OPENCV_CORE_BASE_HPP__ #define __OPENCV_CORE_BASE_HPP__ #ifndef __cplusplus # error base.hpp header must be compiled as C++ #endif #include <cli
