Question

我有

错误C3861：'_ crt_va_end'：找不到标识符

以及

IntelliSense：标识符“_crt_va_end”：未找到标识符

我不知道该怎么做，所以我发布了我的整个项目，希望有人能帮助我。

这是我的代码：

我已经在 Visual Studio 2013 中完全构建了您的项目，没有更改文件，它确实有效！主函数的putput在以下

Cogniac
Ararat
10
200
100
300

Drinks
Water
20
1.25
0.0125
1.2625

Cigarret
Winston
5
100
100
500

301.25

你想要的结果吗？我猜您的问题是编译器，您可以只清理项目并重建它。
