Comments on the program output
Note that the character shown in the first line of output in the previous slide is the character from the Extended ASCII character set that is represented by the numeric value 242 (see http://www.lookuptables.com/).
This character is not correctly depicted in the comments at the beginning of the program in Listing 1.
This is probably because the text editor in Visual Studio 6.0 doesn't recognize eight-bit characters. (It probably recognizes only seven-bit characters.)
Also note that the ± character used earlier is represented by the numeric value 241.
