C. The application of object oriented programming in the old bag of North China University of Techno

Three forms of parameters: (define a swap function for example) 1. Common parameters (value type).

For example: using system;

class test, j = ", i, j);

2. ref (citation type).

Example: using system;

class test, j = ", i, j);

3. out (output type).

using system;

class test

static void swap(out int x, out int y)

Here the initialization of i and j is done.

x = 1; y = 2;

int temp = x;

x = y;

y = temp;

static void main()

In this case, I and J can be initialized without it.

int i , j ;

swap(out i, out j);

i = , j = ", i, j);

The digital technology major of North China University of Technology is mainly PS, 3DMAX, DW, FLASH, etc., such as retouching and modeling, animation, software and programming languages such as C language.

Digital technology (digital media technology) (belongs to the electrical information class) aims to cultivate both technical quality and artistic quality of modern art and design talents, compared with the digital art major, this major slightly pays attention to the cultivation of technical quality, can adapt to the new ** art creation, network multi-** production, advertising, film and television animation, mass media, real estate industry demonstration animation production work.

Here's a suggestion: You have to learn well in the courses offered by the school, which involves whether you can graduate or not. However, you should not expect too much that these courses in the school will bring you a lot of professional ability, if you want to improve your professional ability, you still have to determine what you want to do by yourself, and then completely rely on your own efforts to improve your professional ability.

The school's teaching materials are discipline-based, and they are far from reality.
