C ++内核的Jupyter笔记本错误[cling] [英] Jupyter notebook error for C++ Kernel[cling]

问题描述

我已经在Jupiter Notebook中安装了使用C ++的cling内核但是在执行代码之后

I have installed cling kernel for using C++ in Jupiter notebook but after implementing the code

#include <iostream>
using namespace std;

int main() {

  int a;
  a=9;
  cout<<a;
  return 0;
 }

我收到错误消息--->错误:此处不允许使用函数定义int main(){

I am getting an error as ---> error: function definition is not allowed here int main() {

推荐答案

在这种情况下，您不会编写整个程序代码.就像脚本语言一样.您只需编写应评估的行.不要编写 main 函数:

In cling you don't write the whole program code. It's like a script language. You just write the lines that should be evaluated. Don't write the main function:

#include <iostream>
using namespace std;

int a;
a=9;
cout<<a;

您还可以在保全中定义函数，但是不允许将其他代码写入同一单元格.

You can also define functions in cling but then you are not allowed to write other code into the same cell.
