1.PTA lab assignments
7-1 1.1 N seek one-half sequence and the first N
Content Title: The title requires programming, calculates a sequence of 1/2 + 1/3 + ... + and the first N.
1.1.1 Data Processing
Data are expressed: I used m, i, n these three variables are integer variables, as well as double precision floating point scalar i tem, sum.
Data processing: I used the first N and the sum formula and for statements.

1.1.4 PTA submit a list and description
Commit List Description
Q1: multiple display wrong answer, I checked and no punctuation error.
A1: I reviewed PTA common system errors and the Internet to find relevant information and under the guidance of the students, I found my line of code there is a problem.
1.2 Pursuit of 7-2 minutes and a first N odd sequence
Content Title: The title requires programming, calculates the sequence 1 + 1/3 + 1/5 + ... and the first N.
1.2.1 Data Processing
Data are expressed: I define an integer variable n, two double precision floating-point scalar.
Data processing: I used the for statement.

1.2.4 PTA submit a list and description
Description submit a list of
compilation errors: ignoring malformed.
Partially correct: there is no requirement to consider the subject, and is one of the odd points.
The answer correctly: corrected for m cycles, and each time plus 2.
2. Code peer assessment

Own Code Screenshot
The student code more straightforward, is relatively short, and my long code, use the item variable, not very common, even more profound, difficult to understand ordinary people.

3.3 Summary and perception of learning content
3.3.1 learning content summary
Main points of the fourth week is to use the loop statement, a little like the number of columns in mathematics, so I think it is necessary to learn mathematics, we can develop logical thinking.
3.3.2 Learning Experience
C language is an enigmatic course, review and consolidate, then the heart is not difficult to learn of. It will be very difficult at the beginning, some obscure. Review what you have learned a lot of lessons in advance prep school to learn, it will help us a good grasp this course.
