(Displaying Characters for Given ASCII Codes) Write a program that inputs an ASCII code and prints the corresponding character. Modify this program so that it generates all possible three- digit codes in the range 000–255 and attempts to print the corresponding characters. What happens when this program is run?

Question

What will be an ideal response?

Answer 1

```
// Printing ASCII characters based on codes entered by the user.
#include
using namespace std;

int main()
{
int c;

cout << "Enter an ASCII character code (-1 to end): ";
cin >> c;

// loop until user enters -1
while ( c != -1 )
{
if ( c >= 0 && c <= 255 )
cout << "The corresponding character is '"
<< static_cast< char > ( c ) << "\'\n";
else
cout << "Invalid character code\n";

// ask for another character
cout << "\nEnter an ASCII character code (-1 to end): ";
cin >> c;
} // end while

return 0;
} // end main
```
Enter an ASCII character code (-1 to end): 44
The corresponding character is ','
Enter an ASCII character code (-1 to end): 77
The corresponding character is 'M'
Enter an ASCII character code (-1 to end): 26
The corresponding character is '?'
Enter an ASCII character code (-1 to end): 0
The corresponding character is ' '
Enter an ASCII character code (-1 to end): -1
