c++ - 在通过 scanf 输入 unsigned char 后，变量周围的堆栈已损坏

Question

#include <stdio.h>
int main()
{
    unsigned char y;
    scanf("%hhu", &y);
    printf("%hhu", y);
    return 0;
}

此代码适用于 g++(Dev C++)，但会导致 Visual Studio(2010)中的堆栈损坏，这是 VS 错误还是有任何其他方法可以在 VS 中输入 unsigned char 使用 scanf(); ?

听起来 VS 无法处理 %hhu:https://stackoverflow.com/a/15825386/1715829

The important detail is that you're using Windows, and presumably an outdated or non-conforming C environment (compiler and standard library). MSVCRT only supports C89 (and even then, not entirely correctly); in particular, there was no "hh" modifier in C89, and it's probably interpreting "hh" the same as "h" (i.e. short).
