[Bearbeiten] Beispiel

#include <sstream>
#include <iostream>
#include <iomanip>
int main()
{
    std::istringstream in("10 010 10 010 10 010");
    int n1, n2;
    in >> std::oct >> n1 >> n2;
    std::cout << "Parsing \"10 010\" with std::oct gives:  " << n1 << ' ' << n2 << '\n';
    in >> std::dec >> n1 >> n2;
    std::cout << "Parsing \"10 010\" with std::dec gives:  " << n1 << ' ' << n2 << '\n';
    in >> std::resetiosflags(std::ios_base::basefield) >> n1 >> n2;
    std::cout << "Parsing \"10 010\" with autodetect gives: " << n1 << ' ' << n2 << '\n';
}

Output:

Parsing "10 010" with std::oct gives:  8 8
Parsing "10 010" with std::dec gives:  10 10
Parsing "10 010" with autodetect gives: 10 8
