A week teaching content & goals
Chapter 2 in C programming language - the output of the cyclic structure F 2.4 - Celsius conversion table. It requires students to master cycling program designed to be used for loop to achieve a specified number of times.
Second, this week the head job

1.PTA lab assignments (20 points / questions)
From the PTA elected two focus topics you are most satisfied with the completion of the following topics, select the greater difficulty of the subject, the higher the score, each question 20 points (5 points each), content requirements are as follows:
1.1 questions require programming, calculates sequence - 1/4 + 1/7 - 1/10 + ... and the first N.
1.1.1 Data Processing
数据表达：运用了item sum denominator flag i n 6个变量用item来表示运算，sum作为输出结果，
数据处理：使用了赋值语句 for循环语句1.1.2 Screenshot experiment code
1.1.3 build test data
| Input data | Output Data | Explanation |
|---|---|---|
| 10 | sum = 0.819 | Consistent with the facts |
| 100 | sum = 0.843 | Consistent with the facts |
| 50 | sum = 0.832 | Consistent with the facts |
| -5 | Invalid Value! | Less than 0 |
1.1.4 PTA submit a list and description
1. Compile Error: You entered () in three scanf% d think that there is need to enter a three-digit character
2. Format Error; if used in a for loop statement - else cause the output to match a title 1
7-4 1.2 squared reciprocal portion and a sequence (15 minutes)
This problem requires two positive integers m and n- ( m ≤ n- ) programming, and calculates the sequence m 2. 1 + / m + ( m + 1'd). 1 + 2 / ( m + 1'd) + ⋯ + n- 2 +. 1 / the n- .
1.2.1 Data Processing
数据表达：运用m ，n两个存数变量
数据处理：使用#include<math.h>一个新的数据库 和简单的赋值语句和输入语句1.2.2 Code Screenshot
1.2.3 build test data
| Input data | Output Data | Explanation |
|---|---|---|
| 5 ，10 | sum = 355.845635 | Consistent with the meaning of problems |
