这是一段 Python 代码,其中 edition1 是一个数据框,BOOM 列值为 1 时返回BOOM列,否则返回一个空列表。代码中还向 edition1 添加了一个名为 adjacent 的列,其值为 0。

std::vector<float> temp; temp = temp[1:,] - temp[0:-1,]
这是一个语法错误,无法编译通过。C++中的vector没有类似于Python的切片操作。要计算temp中相邻元素的差值,可以使用for循环或者使用C++自带的算法函数std::adjacent_difference。例如:
```
std::vector<float> temp = {1.0, 2.0, 3.0, 4.0};
std::vector<float> diff(temp.size() - 1);
std::adjacent_difference(temp.begin(), temp.end(), diff.begin());
// 现在diff中存储的是temp中相邻元素之间的差值
```
tableLayoutPanel1.Controls.Add(splitter1, 0, 0);
This code adds a control named "splitter1" to the first cell (0,0) of a TableLayoutPanel named "tableLayoutPanel1".
The TableLayoutPanel is a container control that arranges its child controls in a grid pattern, and the coordinates (0,0) represent the first row and first column in the grid. The Splitter control is used to resize two adjacent controls at runtime by dragging the splitter handle.
Therefore, this code adds a splitter control to the top-left corner of the TableLayoutPanel.
