To show: How to use the C++ char and wchar_t types in C++ programming

 

// the C++ char (string) and wchar_t (wstring) types example

#include <string>

#include <iostream>

using namespace std;

int main(void)

{

const basic_string <char> str1("TEST");

// uses the typedef for string word synonym to basic_string <char>

string str2("TEST");

 

// simple comparison between two objects of type basic_string

cout<<"String str1: "<<str1<<"\nString str2: "<<str2<<endl;

cout<<"Operation: (str1 == str2)?"<<endl;

if(str1 == str2)

cout<<"Strings str1 & str2 are equal."<<endl;

else

cout<<"Strings str1 & str2 are not equal."<<endl;

 

// L - literal qualifier for long

const basic_string <wchar_t> str3(L"TESTING");

// uses the typedef for wstring word synonym to basic_string <wchar_t>

wstring str4(L"JUMPING");

 

// simple comparison between two objects of type basic_string <wchar_t>

cout<<"\nString str3: TESTING \nString str4: JUMPING"<<endl;

cout<<"Operation: (str3 == str4)?"<<endl;

if(str3 == str4)

cout<<"Strings str3 & str4 are equal."<<endl;

else

cout<<"Strings str3 & str4 are not equal."<<endl;

return 0;

}

 

Output example:

 

String str1: TEST

String str2: TEST

Operation: (str1 == str2)?

Strings str1 & str2 are equal.

 

String str3: TESTING

String str4: JUMPING

Operation: (str3 == str4)?

Strings str3 & str4 are not equal.
