Once converted, you need to first call the. Clear () method if you want to complete the conversion operation again.

Similarly borrowing >> and << can also complete other data types, such as double/string,float/string, and so on, which is not mentioned here.

Ps:

The <sstream> library has only recently been included in the C + + standard. (Do not confuse <sstream> with the <strstream> that was deleted before the standard was released.) As a result, older compilers, such as GCC2.95, do not support it. If you happen to be using such a compiler and want to use <sstream>, you need to update it first.
