Astd::basic_string_view over the underlying string object.
#include <iostream>#include <sstream> int main(){// input/output streamstd::stringstream buf1; buf1<<69;int n=0; buf1>> n;std::cout<<"1) buf1 = ["<< buf1.view()<<"], n = "<< n<<'\n'; // output stream in append modestd::ostringstream buf2("test",std::ios_base::ate); buf2<<'1';std::cout<<"2) buf2 = ["<< buf2.view()<<"]\n"; // input streamstd::istringstream inbuf("-42"); inbuf>> n;std::cout<<"3) inbuf = ["<< inbuf.view()<<"], n = "<< n<<'\n';}
Output:
1) buf1 = [69], n = 692) buf2 = [test1]3) inbuf = [-42], n = -42
