For example, if the narrowing conversion error occurs when setting the compile flag `-Werror` (which treats warnings as errors), you may consider disabling or modifying the specific warning causing the issue. C. Use a Type-Safe Solution: Instead of relyingon implicit type conversions, you can...
(3)reinterpret_cast This is the least safe of the casting mechanisms, and the one most likely to produce bugs. Areinterpret_castpretends that an object is just a bit pattern that can be treated (for some dark purpose) as if it were an entirely different type of object. reinterpret_cast用...
warning C4244: 'argument' : conversion from 'float' to 'int', possible loss of data The fix for this warning is to replace the call to abs with a floating point version of abs, such as fabs for a double argument or fabsf for a float argument, or include the <cmath> header and ...
C4838: conversion from 'int' to 'std::size_t' requires a narrowing conversion--why? 發行項 2017/03/03 Question Friday, March 3, 2017 9:26 PM The following gets a compiler warning C4838: conversion from 'int' to 'std::size_t' requires a narrowing conversion. prettyprint 複製 size...
Correct warning for narrowing string conversions Removed a spuriousstatic_castfromstd::stringthat wasn't called for by the standard, and that accidentally suppressed C4244 narrowing warnings. Attempts to callstd::string::string(const wchar_t*, const wchar_t*)now properly emit C4244 about narrowing...
Checks是clang-tidy静态检查的项目,默认情况下是全不选的,但是也不能全选,因为会导致极长的lint时间和很多冗余的抽象warning,可以参考官方的介绍填写需要的项目 可以根据自己需要利用正则开启"performance-*","bugprone-*","portability-*","modernize-*","cppcoreguidelines-*","google-*","readability-*",这些类...
