is urgent, give examples to be considered, but suffice to explain the problem. an application needs to access the database and must specify a connection string in order to obtain a connection. For a program, the connection string is generally fixed after it is run. A, set in the construction code block or construction method, then each time you create the object must be set once, repeat, very troublesome. B, in the program to write the connection str

Why can't I declare a static variable inside a method?
Because a static variable is a common variable for all instances of a class, it is a global variable within the scope of the class. If you define a static variable inside a method, it causes the static variable that is defined to be a local variable
, static global variable is too large, but that can cause stack overflow.
Answer and Analysis:
For a,b: According to the description in this section B), we know that a,b is correct.
For C: According to the description in this overview section a), we know that C is correct (the so-called function reentrant problem, d
For iPhone development, we use instruments when detecting all of them during execution, but sometimes we can eliminate these in the cradle. Static analysise.
You can run build and analyze directly for the build check. You can also check that the build option is checked in getinfo, and each build is executed. However, you will see that it will waste the analysis time during build, resulting in a long build t

Static in C can be used to modify variables, or to modify functions.First look at the time to modify the variable. Variables in C can be divided into the existence of global data areas, stacks and heaps. In fact, we usually say the stack is stack rather than heap, do not confuse.

When compiling your application in the emulator, it is very important that scan-build use the correct GCC version, otherwise you will see some strange compilation errors.Scan-build provides –USE-CC and-use-c++ options. Note that while your main interest is to analyze your project, please note

Like a data member, a member function can also be defined as static, and the preceding addition of a function in a class becomes a static member function. Such as
