1.PTA lab assignments
1.1 crawling worms
A length of 1 inch worm, the bottom of an inch deep N well. The worm is known inch per minute to climb U, but must then rest for 1 minute to climb. During the break, the worm has dropped D inch. In this way, climb and glide repeated. I ask, how long it takes to climb out of worms well?
Here requires less than 1 minute in 1 minutes, and assuming that as long as a particular climb during the worm's head reached the top of the well, then the worm to complete the task. Initially, the worm is lying at the bottom (i.e. a height of 0.
1.1.1 Data Processing
Data are expressed: defines the integer variable N, U, D, s, t. Denote depth, height of rise, fall height, climb displacement time.

1.1.4 PTA submit a list and description
1. Compile Error: forget to add a semicolon after the break.
2. Wrong Answer: break the worm was not calculated.
1.2 Binary Coded Decimal
Input a set of binary characters, and outputs the corresponding decimal number. When you enter the Enter key, enter the end. If non-binary character input, output error input!
1.2.1 Data Processing
Data are expressed: The definition of the character char variable ch, integer variables num, read function getchar.

1.2.4PTA submit a list and description
1 partially correct: forgets the value of 1 in addition must add 1 * 2.
2. partially correct: do not realize the difference between a break and return.
2. Code peer assessment
Students Code:
My code:
1. My classmates code more concise compared to more logical, my code is very long, accounting for a large space, is relatively simple.
2. I am a leap year will be calculated separately in peace, and the students are divided into 31 days of each month, 30 days of each month, and special circumstances in February. He's better, my stupid little brute.

3.3.2 Learning Experience
This week learning the do-while loop and a while, I feel two difficult to distinguish, may be understood not in place. PTA has improved the difficulty of the job, especially in this week's third title Binary Coded Decimal divisible bachelor and fifth questions are not easy to solve the problem.
This week the C language learning is still very abundant and happy.
