Hi all,
How to write the below python pointlist to cpp?
ptlist = [[0,3],[1,7],[2,4],[4,6],[7,8]]
Thank you,
Shruthi

#include <iostream>
#include <vector>
int main()
{
std::vector<std::pair<int, int>> a;
a.push_back(std::make_pair(0, 3));
a.push_back(std::make_pair(1, 7));
a.push_back(std::make_pair(2, 4));
a.push_back(std::make_pair(4, 6));
a.push_back(std::make_pair(7, 8));
for (auto i : a)
{
std::cout << i.first << ' ' << i.second << '\n';
}
}

Or simply:
std::vector<std::pair<int, int>> a = { {0, 3}, {1, 7}, ... };
fixed size:
std::pair<int, int> a[] = { {0, 3}, {1, 7}, ... };
Tank you so much @coder777 , @zapshe
