Working with Character Data
		• Each computer uses a particular character set, two in substantial use today are ASCII and EBCDIC. The vast majority use ASCII. • Character Issues: – Comparing Characters: if (ch >= ‘a’ && ch <= ‘z’) – islower is preferred usage – Converting Digit Characters to Integers: ‘9’ – ‘0’ = 9 – Converting to Lowercase and Uppercase: toupper and tolower can help (#include <cctype>) –  Accessing Characters Within a String: Use position number, e.g. ch = inputStr[2];
