The stringstream class is defined inside the header file.. It works similar to other input and output streams in C++. WebSets the showpos format flag for the str stream. When the showpos format flag is set, a plus sign (+) precedes every non-negative numerical value inserted into the stream (including zeros). This flag can be unset with the noshowpos manipulator. For standard streams, the showpos flag is not set on initialization. Parameters str Stream object … database and application relationship
