C Language Programming Thoughts

The combination of C language course design and the practical application of modern computer technology is a good test of our ability in this stage after we have finished the theoretical course. From the beginning of the algorithm to the beautiful graphical interface after commissioning and the other exciting program is a good learning and exercise process. So that we can consolidate the original theoretical knowledge and develop our ability to flexibly use and combine the knowledge and skills we have learned to analyze and solve practical problems. We realize that our knowledge and abilities can be applied and played in practice. Not only can inspire innovation consciousness but also can develop creative ability, develop communication ability. This internship, although only one weeks, has really benefited me. Through the internship I enriched the computer operation experience deepened the understanding of C language familiar with its environment more

    I learned the C language data types, constants and symbolic constants, variables, C-language operators and expressions, assignment operators and assignment expressions, self-increment and comma expressions, and so on.   think that the instance phase should be a transition stage, through the previous stage of the grammar of the study, there may be many concepts we are more vague, or a lot of things too abstract, this for our second stage of learning to do the instantiation of the preparation, so to speak, The first stage is a class that we build for our learning thing, which tells us what we should do in this area. The second order, that is, this stage, we should go to the previous paragraph of the thing materialized (instantiation of the previously created class), that how to materialize, plainly, to practice some small examples, from the online download of e-book There are many examples of this, if you have to buy books in the bookstore, it should also provide a lot of Inside the example, I have played every time, maybe some people will not personally to play with the hand, what copy and so on, of course, but I personally think, for beginners, it is better to do a good job, after all, these things for us, are more unfamiliar, if each word is finished by themselves, Some code you do not want to remember also difficult, here, we have to understand every example of practice, if you can change some examples slightly, to understand the essence of the thing, let oneself know why do so, then is the best, I usually practice, this step is indispensable, are accustomed to, so also became a reflex, I don't think so. Finally, we should remit the total, the previous examples used in the technology to rationale, and then do a larger example, as far as possible to understand all the knowledge to apply to the inside, just try to, of course, some things can not be integrated together, is also the exclusion of code.

Second, aircraft games (or other software) in the last semester to learn the basic C language statement is how to use it?

Before learning a lot of similar to what printf,scanf,if,else function, and so on, summed up a bit about the following several ways to use:

1, expression statement, empty statement, compound statement.
2, input and output data, input and output functions of the call.
3, compound statement.
4, goto statement and the use of the statement label.
III. analysis of the structure of aircraft games (or other software).

Make simple changes to the code as required by the teacher

1) The program uses functions to form a modular structure
2) in the main function, first call the menu () function to generate the menus
3) Then, by constantly receiving the user's keys, determine what the operation
4) Then set the airplane and the bullet to move
5) display

#include <conio.h>
#include <stdlib.h>
#include <time.h>
#define N 35
