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;
}
