A job in school primary school, using files to achieve access to data, if the database may be simple, but the system is small, so the difference is not very big. Send it to everyone criticized criticism. . .
Description:
This program also needs to build a StudentInfo folder in the program current folder, where you put a StudentInfo.txt file format as follows:
Name ID SEX S1 S2 S3 S4 S5XXX 02281301 Male 88 87 90 82 89YYY 02281302 Male 85 94 86 87 89ZZZ 02281303 Male 84 86 81 82 81
Also build an image folder, put some student avatar, but if you don't want to achieve this, you can don't put it.
