Each student takes four modules: RAD, SD1A, PS and IIS. The passing grade is 40% in every module.
The input data
grades10.txt contains one line per student.
The line begins with the matriculation number and the name. The marks for each of the subjects are given in the sequence RAD, SD1a, PS and IIS. Each of these fields is separated by the tab character.

Print the names of the students who have passed the RAD module.
Try adding an if statement, for example try replacing

if (iis<50) System.out.println(name);
Semester pass list
Print the names of the students who have passed all four modules.
You need to print some names but not other. An
if statement will do this.
