Output produced by the nested loop example program
increment operator is used to increment the count. Because
s
and
t
are defined
locally there is, in fact, no need to use different variables and the following code
would produce
exactly
the same result:

loop2.c
*/
/* Language:
Borland C++ 4.5
*/
/* Output:
Table of decimal, hex. and ASCII characters */
/* Note:
Program runs in a DOS console window

while (s < 4)

}

Inputs and prompts
A single character can be returned from the standard input (usually the keyboard)
by means of the
getchar()
function. The following routine shows how a single
