C++ 如何处理输入多行整数的问题

Answer 1

#include <sstream>
#include <string>
#include <vector>

std::string line, num;
std::vector<std::vector<int>> v;
size_t linenum = 0;
while (getline(cin, line)) {
    std::istringstream iss(line);
    while (line >> num) {
        v.push_back(vector<int>());
        v[linenum].push_back(stoi(num));
    }
    ++linenum;
}

I just finished reading C++ primer, and this is probably the approach.

You are doing a question on OJ. If it is OJ, the required input is actually different from what you understand. You can refer to this
