8.3 Functionality of Imperative Languages 239 In the exercises, we ask you to compare the syntactic differences that surface in these examples. The use of uppercase and lowercase in identifiers is part of the culture of a language. In our examples, we have tried to stay with the style that is common within the language’s culture. For example, most C++ program- mers use all uppercase for named constants and begin variable names with lowercase, while Ada and VB.NET programmers tend to begin variable names with uppercase letters. Input/Output Structures In our pseudocode algorithms we have used the expressions Read and Write to indicate that we were interacting with the environment outside the program. Read was for getting a value from outside the program and storing it into a variable inside the program, and Write was for displaying a message for the human to see. Machine-language instructions for input and output are very primitive.
