# 像Python一样玩C/C++
在Python中我们可以使用`Jupyter Notebook`直接看到结果,例如:
```c
l = [1,2]
l
```
直接输出:
```
[1,2]
```
那当使用C++的时候,例如:
```cpp
map<string, int> mp{
{"one", 1},
{"two", 2},
{"three", 3},
{"four", 4}
};
```
如果要输出,就得循环遍历,可否直接输出结果呢?
so easy!!! `Jupyter Notebook`可以解决一切问题,哈哈~
## 如何在Jupyter中玩C++
在github上有一个仓库如下所示
> https://github.com/QuantStack/xeus-cling
`xeus-cling` 是一个用于C++的Jupyter内核基于C++解释器和Jupyter协议xeus的原生实现。
目前支持Mac与Linux但不支持Windows。
安装也是非常简单首先安装好Anaconda在里面创建一个虚拟环境
```
conda create -n cling
```
切换进去:
```
conda activate cling
```
给新环境安装`jupyter``notebook`
```
conda install jupyter notebook
```
使用`conda-forge`安装`xeus-cling`
```
conda install xeus-cling -c conda-forge
```
为了加速安装请记得给Anaconda配置源
检查是否安装好了内核(kernel)
```
jupyter kernelspec list
```
输出:
```cpp
python3 /home/xxx/anaconda3/envs/cling/share/jupyter/kernels/python3
xcpp11 /home/xxx/anaconda3/envs/cling/share/jupyter/kernels/xcpp11
xcpp14 /home/xxx/anaconda3/envs/cling/share/jupyter/kernels/xcpp14
xcpp17 /home/xxx/anaconda3/envs/cling/share/jupyter/kernels/xcpp17
```
打开`Jupyter Notebook`就可以看到看到kernel了。
启动`Jupyter Notebook`
```
jupyter-notebook
```
## 如何在Jupyter中玩C
只需要安装c kernel即可
可以直接在当前环境中创建c kernel也可以新开一个环境安装下面是在当前环境中直接安装。
```
pip install jupyter-c-kernel
install_c_kernel
jupyter kernelspec list
```
此时,就输出:
```cpp
c /home/light/anaconda3/envs/cling/share/jupyter/kernels/c
python3 /home/light/anaconda3/envs/cling/share/jupyter/kernels/python3
xcpp11 /home/light/anaconda3/envs/cling/share/jupyter/kernels/xcpp11
xcpp14 /home/light/anaconda3/envs/cling/share/jupyter/kernels/xcpp14
xcpp17 /home/light/anaconda3/envs/cling/share/jupyter/kernels/xcpp17
```
启动`Jupyter Notebook`
```
jupyter-notebook
```
