[Bearbeiten] Beispiel
#include <iostream> #include <sstream> int main() { std::cout << "The number 42 in octal: " << std::oct << 42 << '\n' << "The number 42 in decimal: " << std::dec << 42 << '\n' << "The number 42 in hex: " << std::hex << 42 << '\n'; int n; std::istringstream("2A") >> std::hex >> n; std::cout << std::dec << "Parsing \"2A\" as hex gives " << n << '\n'; }
Output:
The number 42 in octal: 52 The number 42 in decimal: 42 The number 42 in hex: 2a Parsing "2A" as hex gives 42
