1.1 Title integer 6-1 determines a sum of the squares of the digits can be divisible by 5

Title Description: Function to write fun, which is: determining an integer and the sum of the squares of the digits can be divisible by 5, can be divisible by 5 returns 1, and 0 otherwise.

1.1.1 Data Processing

• Data are expressed: Defines the integer variable sum, i, sum represents the sum of the digits of the square, i represents the ten-one hundred digital
• Data processing: Use the scanf () input function, while loop statement calculated
• Function parameters: calling function main (), the called function fun (), line parameter n, the argument i, sum

1.1.2 Screenshot experiment code

1.1.3 build test data

Input data	Output Data	Explanation
12	1	1 plus the square of the square is equal to 2 5
100	0	The sum of the digits of the square can not be divisible by 5
225	0	It can not be divisible by 5
310	1	Squared plus 1 to 3 and the sum of the squares divisible be 5

1.1.4 PTA submit a list and description

• Do not know when you see the topic you want to use the while statement, heard students say I know to use

1. Compile error: while () after more than a semicolon
2. Compile Error: sum% 5 == 0 wrote the sum% 5 = 0
3. Compile error: n / = 10 n = 10 wrote
4. Compile Error: n = 0 had a little! "!"
5. Partially correct: sum unassigned initial value sum = 0
6. Run timeout: n = 0 n = 1 assigned to the!!
7. Partially correct: I SUM = SUM + I written SUM = SUM I

1.2 Title 6-3 narcissistic number determination

Description Title: The title required to achieve a function, it is determined whether any integer number daffodils (three digits must be equal on every digit number and the number itself and cubic). E.g. 153 + 5 = 1 ^ 3 ^ 3 ^ 3 + 3 + 1 = 125 + 27 = 153, and 1 155 or not narcissistic number. If the number of daffodils, the function returns 1, otherwise it returns 0.

1.2.1 Data Processing

• Data are expressed: defines the integer variable a, b, c, representing one hundred ten, digit
• Data processing: if-else statements used for outputting the results
• Function parameters: calling function main (), the called function func (), the reference line N, arguments a, b, c

1.2.3 build test data

Input data	Output Data	Explanation
10	0	Not the three-digit
100	0	Members of the cube and the number is not equal to the number itself
370	1	Cubic Cubic plus equals 370 3 7
1123	0	1123 is the four-digit

1.2.4 PTA submit a list and description

1. Compile Error: int func (const int N) after more than a semicolon
2. Compile Error: N == less a "="
3. Compile error: int behind a, b, c defines a plurality N
4. Compile error: c = N% 10 = write of Na C 100 B- 10
5. Compile Error: N written n

2. Code peer assessment

2.1 Screenshot students Code

Own Code Screenshot

Code comparison

1. She is both a integer variable defined separately
2. She did not call the scanf function, but direct use do-while statement
3. She also used the if-else statement
4. I am a direct return (sum% 5 == 0), she defines a z, and then finally return z
5. I think she's the code more complicated, but it seems more than I seem easier to understand

2.2 Screenshot students Code

Own Code Screenshot

Code comparison

1. She defines only the two of integer variable, I define three integer variable of the same nature
2. She uses a while statement and the if-else statement, I only used the if-else statement
3. I call scanf function, she used directly while statement
4. Our data expressions are not the same, I am a, b, c are carried out operation, a direct expression of her solve the problem
5. Her straightforward than some of my code looks simple, but I think my code easier to understand

3.3 Summary and perception of learning content

3.3.1 learning content summary

3.3.2 Learning Experience

1. Teacher in the class talked about the programming problem, when the result of their own doing was wrong many times, on the DEV-c ++ compiler is right, but wrong a debugging, and finally asked the students to do it
2. This week more than a job function parameters and mind mapping, feel knowledge points minds are connected to a line after finishing mind mapping, knowledge of the knowledge of what has been strengthened many
3. Weekly assignments will be a little more different topic every time, you can learn something new, previously learned markdown syntax, and then learned to make a line graph, and now learned to do mind mapping
4. Before each spend doing blog work very long time, in particular format is always wrong, and now spend less time, and did not appear the wrong format
5. Learn self-learning is very important, PTA work is always ahead of us, we have to learn to self-study, to absorb more knowledge
