This style is also full of opportunity for errors.

We have to learn the notation, but doing so is relatively simple: There is no standard way of directly using the symbolic form of the buffer size,m ma ocmo x, in thes sc ca an nf f format string, so I had to use the integer literal.

However, skipping initial whitespace is the norm and the other versions of the program skip whitespace. To summarize, to solve the original simple problem, I had to introduce loops, tests, storage sizes, pointers, casts, and explicit free-store management in addition to whatever a solution xeitel the problem inherently needs.

What we want is for the string to expand to cope with the input.

The simplest specific example I can think of is a program to find the mean and median of a sequence of double precision floating-point numbers read from input. To user re co,o al l lo oc c while staying portable, I had usem ma al l lo oc c rather thann ne ew w.

f The main problem is that this simple C- style solution is shoddy. All rights reserved – 4 – store. A conventional C-style solution would be:.

As a first attempt we could simply prevent the array overflow by usings sc ca an nf f in a more appropriate manner:. Thus they acquire a habit that is hard to break and leave a trail of programaf code behind.

However, consider the added conceptual load on a novice. For such programs, simplicity and type safety is what matters. However, the main part of the program is conceptually simple and differs only notationally from the problem statement.

That is bad style and a maintenance hazard. As a first attempt we could simply prevent the array overflow by usings sc ca an nf f in a more appropriate manner: For toy programs and for students who program only to get a good grade in a nonessential course, this simplification would be sufficient.

What design and programming techniques do we want to emphasize?

A conventional C-style solution would be: It argues briefly that lessons from these simple examples are relevant to large programs. What subsets of the language do we want prpgramar emphasize progamar real code?


What doesu us si in ng gdo? Efficiency is not an issue in a trivial program like the one above.

However, real systems often have parts where efficiency is essential. Here, I simply did something obvious to avoid porgramar discussion going off on another tangent.

Compared to the previous versions, this seems rather complex. By reducing com and complexity, we reduce development time, ease maintenance, and decrease the cost of testing.

The key to major improvements is a reduction of the size and complexity of the code we write through the use of libraries. Someone using the C-style approach would have to carefully consider which approach would form a good deiyel for further teaching and eventual use. What does i in nc cl lu ud de emean?

However, for professional programmers efficiency is a major issue.
