[编辑]示例

#include <iostream>#include <sstream>   int main(){// 输入/输出流std::stringstream buf1; buf1 <<69;int n =0; buf1 >> n;std::cout<<"1) buf1 = ["<< buf1.view()<<"], n = "<< n <<'\n';   // 追加模式的输出流std::ostringstream buf2("test", std::ios_base::ate); buf2 <<'1';std::cout<<"2) buf2 = ["<< buf2.view()<<"]\n";   // 输入流std::istringstream inbuf("-42"); inbuf >> n;std::cout<<"3) inbuf = ["<< inbuf.view()<<"], n = "<< n <<'\n';}

输出:

1) buf1 = [69], n = 69 2) buf2 = [test1] 3) inbuf = [-42], n = -42
