Ideas in this flowchart

Comparing strings and characters
Comparison operators can be used for single characters
Character comparison depends on the ASCII text table
Each alphanumeric character, symbol, and whitespace character has an associated integer
ASCII character codes range from 0 to 127
The expression ('A' < 'a') is true
Uppercase letters are ordered before lowercase letters in ASCII
'A' has code 65 and 'a' has code 97
Because 65 < 97, the character comparison is true
Additional comparison examples are provided in a table

"16.1.2. Comparing Strings and Characters The comparison operators in Table 16.1 can also be used for single characters because of the nature of the ASCII text table (see Table 2.4). Each alphanumeric character, including the various symbols and whitespace characters, is associated with an integer 0–127. We can therefore write statements like ('A' < 'a') , which is true since uppercase letters are ordered before lowercase letters in the ASCII table ( 'A' is 65 and 'a' is 97 and so 65 < 97 is true ). Several more examples can be found in Table"
