程序在发布版本中编译但不调试 [英] Program compiles in release build but not debug

问题描述

大家好，我在VS 2015中构建遗留C ++程序时遇到问题，它在Release版本中没有错误，但是在Debug中没有错误，它在这个版本中包含这个版本

Hi All, I'm having problems building a legacy C++ program in VS 2015, it builds without errors in Release but not in Debug, the line it baulks at it this

gets_s( ch );

gets_s too few arguments for call

为什么发布版本是我的问题



我尝试过：

Why does it build in Release is my question

What I have tried:

<pre lang="c++">
gets_s( ch );

gets_s too few arguments for call

推荐答案

这可能是由 gets_s（）函数的模板重载引起的，该函数可能与调试版本的行为不同。 />


我在VS 2017中试过这个并且它在调试模式下编译得很好：

This is probably sourced by the template overload of the gets_s() function which might behave differently with debug builds.

I tried this with VS 2017 and it compiles fine in debug mode:

char ch[10];
gets_s(ch);

因此可能会对你的 ch 变量的声明感兴趣。



为避免错误，您可以明确传递大小：

So it might be of interest how your ch variable is declared.

To avoid the error you can pass the size explicitly:

char ch[10];
gets_s(ch, sizeof(ch));
