Functional requirements:
(1) to use an array to save the student information, such as can define a 3 x 5 two-dimensional string array, each line array to save a student's information, arrays are defined as follows:
Students, string []={{" zhang ", "95001", "95", "97", "87"},
{" bill ", "95002", "93", "90", "90"},
{" detective ", "95003", "89", "92", "86"}}
You can also define more students information,
(2) according to the user to enter student id in the array to find the student information:
If you can find the ZhaXue, showed its name, student number, grade and grade point average, as shown in figure 11,
As cannot find ZhaXue number, use dialog displays "the student number was not found, please re-enter your student id!" ,
(3) to generate the installer (released),

Figure 11 query student information
Tip:
(1) the definition of student information array should be button_click method, do not put in any one button_click method,
(2) because the array is defined type string, so the two subjects are conserved as type string, when calculating the grade point average, need to convert subjects to int, then to calculate average scores,
