1.PTA Experiment assignment
Title Description ： Programming , Calculation sequence 1 - 1/4 + 1/7 - 1/10 + ... Before N Sum of items .
1 Screenshot of experimental code
1.1.2 Data division
Data expression ： Define variables with denominator,flag,i,n. use int Definition . The data type is the double precision floating-point type of the basic type double
Data processing data ： It was used for loop , Formula is item=flag*0.1/denominator;sum=sum+item;d=d+3.
explain ：1： Three decimal places are sum=%.3f
2 There's something wrong with some of the spaces and symbols
1.2.2 Data processing ：
Data expression ： Definition i,n,, floating-point sum,a,b;
Data processing data ： It was used for loop
explain ： At the beginning of writing this topic , I don't know the train of thought , Later, I asked my classmates , In the end, we get the right result , After finishing the problem , I understand that we should learn from the best people .
1.3 7-4 Before the square root sequence N Xiang He (15 branch )
Calculate the sequence of square roots √1+√2+√3+⋯ Before N Sum of items
1.3.1 Screenshot of experimental code
Data expression ： Definition n,s,item,i
Data processing data ： Use of the for loop .
explain ： There have been several compilation errors , Format error , After repeated verification , Get the right answer , Understand, practice compiling code .
2. Reading the code （-5——5 branch ）
Find a good code , Understand code functions , And tell us what you can learn from the code you have chosen . Reference website ：
ACM Problem solving
leecode Interview several questions website , Find a simple topic to read and analyze .
Be careful ： This part of the answer is too general to be reversed 5 branch .
Topic type ： Find the greatest common factor and the least common multiple .
The learning ：1. It was used while loop , Learn to divide for Outside the new cycle
2. I've learned to clear my mind , Compile code faster and better .
3. Learning summary （15 branch ）
3.1 Learning progress bar （5 branch ）
3.3 Learn to understand （5 branch ）
Please review your learning process this week , If you have new ideas or new ways , Please make a note in time .
Before you know it, it's the third week , This week, the teacher taught us more code compilation skills , such as for loop , How to find the interleaved sequence n Xiang He .
The homework assigned by the teacher this week is also very complicated , You have to use 5,6 Hours or more to finish it , I understand that this is one of our
test , Not only can we quickly understand the relevant knowledge , And it can stimulate our interest in typing code . I believe these problems can make us enjoy solving them
The joy of , Let's be stronger .
