Question

C++如何读取CSV文件并赋值到二维数组里

Answer 1

#include <string>#include <sstream>#include <iostream>int main() { std::string str("123,56,34"); std::stringstream ss(str); while (std::getline(ss,str,',')) { std::stringstream s(str); double num; s >> num; std::cout << num << std::endl; }}

你只要搞清楚 std::getline 就可以了
