Write a c program using string functions

This article replaces the previous one with the same title. This issue has been fixed in the following implementation. Update note The article has been updated on the 19th of June to integrate 3 fixes: Introduction When it comes to software development in a professional environment, heterogeneity is the rule not the exception:

Write a c program using string functions


Simple Report all non-const variables declared at namespace scope. Avoid singletons Singletons are basically complicated global objects in disguise. In a multi-threaded environment, the initialization of the static object does not introduce a race condition unless you carelessly access a shared object from within its constructor.

Note that the initialization of a local static does not imply a race condition. However, if the destruction of X involves an operation that needs to be synchronized we must use a less simple solution.

If you, as many do, define a singleton as a class for which only one object is created, functions like myX are not singletons, and this useful technique is not an exception to the no-singleton rule.

Enforcement Very hard in general. Look for classes with names that include singleton. Look for classes for which only a single object is created by counting objects or by examining constructors. Make interfaces precisely and strongly typed Reason Types are the simplest and best documentation, have well-defined meaning, and are guaranteed to be checked at compile time.

Also, precisely typed code is often optimized better. That is error-prone and often verbose. Consider using a variant or a pointer to base instead. For generic code these Ts can be general or concept constrained template parameters. An int can carry arbitrary forms of information, so we must guess about the meaning of the four ints.

Most likely, the first two are an x,y coordinate pair, but what are the last two? Comments and parameter names can help, but we could be explicit: Hard to do well Look for member functions with many built-in type arguments. State preconditions if any Reason Arguments have meaning that may constrain their proper use in the callee.

The type system cannot easily and naturally express that, so we must use other means. For now, we place it in the definition function body. Expects is described in GSL. Note Prefer a formal specification of requirements, such as Expects p. Note Most member functions have as a precondition that some class invariant holds.

That invariant is established by a constructor and must be reestablished upon exit by every member function called from outside the class. The rules for passing pointers. Prefer Expects for expressing preconditions Reason To make it clear that the condition is a precondition and to enable tool use.

This can make them hard to distinguish from ordinary code, hard to update, hard to manipulate by tools, and may have the wrong semantics do you always want to abort in debug mode and check nothing in productions runs? Once language support becomes available e.

Note Expects can also be used to check a condition in the middle of an algorithm.

Note No, using unsigned is not a good way to sidestep the problem of ensuring that a value is nonnegative. Enforcement Not enforceable Finding the variety of ways preconditions can be asserted is not feasible.

Warning about those that can be easily identified assert has questionable value in the absence of a language facility. State postconditions To detect misunderstandings about the result and possibly catch erroneous implementations. Note Postconditions are especially important when they relate to something that is not directly reflected in a returned result, such as a state of a data structure used.

Example Consider a function that manipulates a Record, using a mutex to avoid race conditions: Stating the postcondition would have made it clear: Only postconditions related to the users can be stated in the interface.

Enforcement Not enforceable This is a philosophical guideline that is infeasible to check directly in the general case. Domain specific checkers like lock-holding checkers exist for many toolchains.
