The value of the character pointed to by theget pointer.
#include <iostream>#include <sstream> int main(){std::stringstream stream("Hello, world");std::cout<<"sgetc() returned '"<<(char)stream.rdbuf()->sgetc()<<"'\n";std::cout<<"peek() returned '"<<(char)stream.peek()<<"'\n";std::cout<<"get() returned '"<<(char)stream.get()<<"'\n";}
Output:
sgetc() returned 'H'peek() returned 'H'get() returned 'H'
(removed in C++17) | reads one character from the input sequence and advances the sequence (public member function)[edit] |
| advances the input sequence, then reads one character without advancing again (public member function)[edit] |
