During programming , I find that these are several programs ,during I’am doing some programming .

for example , while I make the data struct in the this field,I also realize that I miss the length 

Now ,I think I should better find the most meta of the object. 

and the program also have some problem like this:

1.the function of functions is not one poupose .

for example ,in SearchInfo function,the judging person’s code is in the array or not .I think you could also use function.

finally , I last say that using the adding programming thought is a good idea!
