Took a course on software security at Coursera. Here is a list of readings from the professor:Week 1ReadingsRequired ReadingThe only required reading this week is the following: Common Vulnerabilities Guide for C programmers. Take note of the unsafe C library functions listed here, and how they is the source of the buffer overflow vulnerabilities. This list is relevant for the project and this week ' s quiz. (Reference) Memory layout. Exp

is negative, the numerator denominator is multiplied by 1 (For comparison size multiplied by the molecular size symbol will not change)The last is the overloading of operators, where +, Where the Add function is specifically implemented as follows:Since subtraction is the same as adding a negative number, the division is actually multiplying by a reciprocal, and here is no longer repeatingThe other molecule cannot be 0, so the exception is handled accordingly.(2) extension of the operator(3) Pr

For the primary four mixed operation of the software design, through the analysis of design requirements, I think for this software in the future to facilitate the expansion of functionality, you can use the last semester of the "compilation Principle" in the lesson of the LL1 grammar analysis and guidance translation algorithm to achieve. The benefits of doing this include the following points:1. Because L

"Design Ideas"1. User initializes an array2. Define Tempmax as a temporary maximum value, define MAX, initial array[0]3. Use the loop from array[1] to determine whether the Tempmax value is positive or negative, if the positive tempmax is positive, the Tempmax value becomes Tempmax plus the number of traversal, if the Tempmax value is negative, the Tempmax value becomes the traversed number.4. Compare Max and Tempmax value sizes, if Max teenager Tempmax value is assigned to Max"Program source Co

. (Hint: there is more than one problem)Requirements:(1) Write the question(2) Write down the reason why the problem arises(3) Give the modified code2, write a paragraph for the integer array sorting code, explain your design ideas, and use the error-guessing method to give a possible error (at least 5), design the test case, and use JUnit to write unit tests to test. (assuming that the passed-in parameter has been determined to be an integer array)Requirements:(1) Write code, and conform to cod

Topic One:1. Write a Java program that parses the frequency of occurrences of each word in a string and displays the word and the frequency at which it appears. (the words are separated by a space, such as "Hello World My First Unit Test");2. Write unit tests for testing;3. Use Elcemma to view code coverage, which requires coverage of up to 100%.Code:Import Java.util.HashMap;Import Java.util.Iterator;Import Java.util.Scanner;public class Test1 {Private hashmapprivate int wordscount;Public Test1

There are several types of telephone numbers available in a university in Beijing: the number on the campus is 4 digits, the 1th digit is not 0; the outside telephone is divided into the city telephone and the field telephone two class, pulls off-campus telephone to first unplug 0, if the city telephone then then pulls out 8 digits (first not 0), If the field calls, unplug the 3-digit area code and then unplug the 8-digit number (the first digit is not 0).Define the above telephone number using

The second semester of software engineering finally ended before entering the third year. This semester was less than two weeks old, and the project period was shorter. In the security field, the subject matter was more professional, and the team leader was under more pressure. However, this short-term and efficient Android Application Layer development and learning has also laid the foundation and confidence for myself and my projects, and given me a
