C++之类型转换函数(七)
输出结果:
root@txp-virtual-machine:/home/txp# g++ test.cpp
test.cpp: In function ‘int main()’:
test.cpp:42:15: error: conversion from ‘Test’ to ‘Value’ is ambiguous
Value v = t;
^
test.cpp:41:10: note: candidates are:
Test t(100);
^
test.cpp:31:5: note: Test::operator Value()
operator Value()
^
test.cpp:14:6: note: Value::Value(Test&)
Value(Test& t)
3、小结:
无法抑制隐式的类型转换函数调用
类型转换函数可能与转换构造函数起冲突
当然工程中可能比较习惯用 Type toType()的公有成员代替类型转换函数(就是换了种写法)
