}
Program Run Result:
Step two: Copy to a redhat system and read the contents of these TXT documents with the cat command
Step three: read out the contents of these TXT documents in C + +
Program code:
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream cin1("testASCII.txt");
char s1a[100];
char s1b[100];
cin1.getline(s1a, 100, ‘\n‘);
cin1.getline(s1b, 100, ‘\n‘);
cout << "ASCII:" << endl << s1a << endl << s1b << endl << endl;
ifstream cin2("testBigEndianUnicode.txt");
char s2a[100];
char s2b[100];
cin2.getline(s2a, 100, ‘\n‘);
cin2.getline(s2b, 100, ‘\n‘);
cout << "BigEndianUnicode" << endl << s2a << endl << s2b << endl << endl;
ifstream cin3("testUnicode.txt");
char s3a[100];
char s3b[100];
cin3.getline(s3a, 100, ‘\n‘);
cin3.getline(s3b, 100, ‘\n‘);
cout << "Unicode" << endl << s3a << endl << s3b << endl << endl;
ifstream cin4("testUTF32.txt");
char s4a[100];
char s4b[100];
cin4.getline(s4a, 100, ‘\n‘);
cin4.getline(s4b, 100, ‘\n‘);
cout << "UTF32" << endl << s4a << endl << s4b << endl << endl;
ifstream cin5("testUTF7.txt");
char s5a[100];
char s5b[100];
cin5.getline(s5a, 100, ‘\n‘);
cin5.getline(s5b, 100, ‘\n‘);
cout << "UTF7" << endl << s5a << endl << s5b << endl << endl;
ifstream cin6("testUTF8.txt");
char s6a[100];
char s6b[100];
cin6.getline(s6a, 100, ‘\n‘);
cin6.getline(s6b, 100, ‘\n‘);
cout << "UTF8" << endl << s6a << endl << s6b << endl << endl;
return 0;
}
Operation Result:
Conclusion: ASCII-encoded files can read English characters, UTF8 encoded files, C + + in Linux can read Chinese and English
