"Soft Examination article"--Summary of knowledge points in soft examination (I.)

Soft test to now ready to do the work is almost, in the process of choosing a problem, found some of their own weak points, always love a few points of error,

Here's a little bit of a summary.

compiling programs and interpreting programs

Compiler: Will source program-"Target language program, do not participate in the specific implementation process

Following several processes:

Among them, lexical analysis and parsing can be found in the compilation phase, if there is an error, cannot compile successfully. While semantic analysis examines static semantic errors, it does not

affect compilation results.

Interpreter: Source program-"intermediate code, participate in the implementation of domestic to you, generally in the course of the operation to explain."

Commonly used intermediate code: suffix (also known as inverse polish), tree, ternary, four Yuan style.

The intermediate code generated by the explanation is typically in scripting language.

Software Quality Model

Application principle: Find the Object

Entity diagram:

Data flow and processing

Jingle: Parent-child data different names      .

Data Flow consistency, maintain four points: 1, the balance of the parent and sub-graphs, 2, data conservation, 3, local data storage, 4, a processing output data

The stream cannot have the same name as the input data stream for the processing.

Algorithm

Jingle: Direct bubbling is basically classified as stable.

Summarize

a summary of the need to summarize the knowledge is very much, the summary still need to continue, or wait for the next article to continue it ~ knowledge a little broken ~
