小编use*_*257的帖子

考虑以下代码:

#include <iostream>
#include <cmath>

int main() {
    int i = 23;
    int j = 1;
    int base = 10;
    int k = 2;
    i += j * pow(base, k);
    std::cout << i << std::endl;
}

它输出"122"而不是"123".这是g ++ 4.7.2(MinGW,Windows XP)中的错误吗？

我试图运行hibernate-tutorial-hbm位于模块basic的文件夹中的示例代码从Hibernate的教程。我将代码导入Eclipse，添加了

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

到根目录，pom.xml因为我正在使用Java9。执行时，Run as -> Maven test我在控制台上收到以下错误：
