Input and Output of string, wstring, cout, wcout, and Chinese characters

In C ++, you can directly store and output Chinese characters using string and cout:

# Include <iostream> # include <string> using namespace STD; void main () {string S1 = "first"; cout <S1 <Endl ;}

Normal output:

First

However, sometimes wstring is used to store Chinese characters.

• Import the locale header file
• L must be added before Chinese characters and stored with wstring
• Change the local language before output, wcout. imbue (locale ("CHS "))
• Output with wcout

# Include <iostream> # include <string> # include <locale> using namespace STD; void main () {string S1 = "first"; wstring S2 = l "second "; cout <S1 <Endl; wcout. imbue (locale ("CHS"); wcout <S2 <Endl ;}

The result is:

First

Second
