A starting point could be as follows.
Type C-c C-c to evaluate.
Type C-c C-v v to expand the source.

#+BEGIN_SRC C++ :flags -std=c++11

#include <vector>
#include <iostream>
using namespace std;

class Solution {
    vector<int> twoSum(vector<int>& nums, int target) {
      vector<int> result;
      return result;

vector<int> nums = {2, 7, 11, 15};
int target = 9;

int main()
  Solution solution;
  for (int x : solution.twoSum(nums,target))

I'd like to write a blog about leetcode solutions in c++. How can I evaluate those c++ code snippet using org babel?

    1 Array

      1.1 Two Sum

Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

Given nums = [2, 7, 11, 15], target = 9,

Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].

|class  Solution  {
     vector<int>  twoSum(vector<int>&nums,int  target)  {


I need to add default headers and pass arguments to the entry class.
