31. Visual Studio 2015的项目当使用Visual Studio 2019打开时碰到问题

Posted by haifeng on 2020-09-24 15:44:11 last update 2020-09-25 11:04:52 | Answers (0) | 收藏


D:\work\cs\c++\vs2019\calculator_vc\calculator\calculator\calculator.vcxproj : warning  : 无法找到 Visual Studio 2010 (v100) 的生成工具。若要使用 Visual Studio 2019 (v142) 生成工具进行生成,请单击“项目”菜单或右键单击解决方案,然后选择“重定向解决方案...”。安装 Visual Studio 2010 (v100) 可使用 Visual Studio 2010 (v100) 生成工具进行生成。

 


 

错误 LNK2019 无法解析的外部符号 _fprintf,函数 _crypt_argchk 中引用了该符号 calculator D:\work\cs\c++\vs2019\calculator_vc\calculator\calculator\tomcrypt.lib(crypt_argchk.obj) 1

 

解决办法:

右键calculator项目, 点击【属性】,在【配置属性】-->【链接器】-->【输入】-->【附加依赖项】中加入 legacy_stdio_definitions.lib

32. Calculator 中的函数

Posted by haifeng on 2020-05-05 10:27:03 last update 2020-05-05 10:27:03 | Answers (0) | 收藏


在 Calculator 中可以使用 listfunctions() 函数列出当前系统中预设的所有函数.

listfunctions() 还可以接受参数 1, 即 listfunctions(1), 它将列出所有函数的原型. 

如果要查看函数的用法, 可以使用 help() 函数, 比如 help(len) 将显示 len() 函数的用法.

36. [DevPlan] 在Calculator中加入求解一元n次方程的功能

Posted by haifeng on 2019-10-09 09:56:03 last update 2022-09-15 08:05:08 | Answers (0) | 收藏


开发计划

在Calculator中加入求解一元n次方程的功能, 这里 $n\leqslant 3$.

 

开发日志

 

首先要解决的问题是将输入的不规范方程表达式转换为标准的形式. 比如:

x^2-3x^3+7x-9=0   ===>  -3*x^3+1*x^2+7*x-9==0

系统存入系数向量 w=(-3,1,7,-9), 或者 w=(-9,7,1,-3), 后者方便记忆或转换, 比如 w[i] 即 x^i 的系数
