C++生成标准的ASCII编码表的代码

下面内容段是关于C++生成标准的ASCII编码表的内容。

The standard ASCII table defines 128 character codes (from 0 to 127), of

which, the first 32 are control codes (non-printable), and the remaining 96

character codes are representable characters:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{  int i,j;

    char cmd[32][4]= {"NUL","SOH","STX","ETX","EOT","ENQ","ACK","BEL","BS","TAB",

                      "LF","VT","FF","CR","SO","SI","DLE","DC1","DC2","DC3","DC4","NAK",

                      "SYN","ETB","CAN","EM","SUB","ESC","FS","GS","RS","US"};

    cout << "The standard ASCII table defines 128 character codes (from 0 to 127),";

    cout << "n of which,the first 32 are control codes (non-printable), and the";

    cout << "n remaining 96 charactercodes are representable characters:n";

    for( i = 0 ; i < 10 ; i++)

        cout << setw(4) << i;

    for( i = 0x41 ; i < 0x47 ; i++)

        cout << setw(4) << static_cast<char>(i);

        cout << endl << "-- ";

    for( i = 0 ; i < 16 ; i++)

    cout << left << "--- ";

    for( i = 0 ; i < 2 ; i++ )

        {

            cout << endl <<  i << "| " ;

    for(j = 0 ; j < 16 ; j++)

        }

    for( i = 2 ; i < 8 ; i++ )

        {

        cout << endl << i << "| " ;

    for( j = 0 ; j < 16 ; j++)

        }

    cout << endl << endl;

    return 0;

}
