cout << endl;
return 0;
}The output of the code is:
<=>?ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_‘abcdeNote that, although the character variableais evaluated as an integer, it is
printed as a character through the output.
Exactly the same output would have been obtained if theforloop were
replaced either by:
for (i=60; i<=101; i++)
{
cout << (char) i;
}or by:
for (i=60; i<=101; i++)
{
cout << char(i);
}The statements(char) iandchar(i)invoke integer-to-character conversion
functions that perform an operation known astypecasting.
To further illustrate that characters are stored as ASCII encoded integers,
we consider the instructions:
char d = 66;
char e = ’B’;
cout << d << e << endl;The screen display is:
BBPeculiarities of the input buffer
The following code asks for the user’s name and age, and then prints the
information on the screen:
