C++ convert string to uint64_t

I am trying to convert from a string to a uint64_t integer. stoi returns a 32 bit integer, so it won't work in my case. Are there other solutions?

Try this:

#include <iostream>
#include <sstream>
#include <cstdint>

int main() {
    uint64_t value;
    std::istringstream iss("18446744073709551610");
    iss >> value;
    std::cout << value;
}
