Run this code
#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 = 69 2) buf2 = [test1] 3) inbuf = [-42], n = -42
