. How to count off? Define a variable count log off3. Once the count is 3, what do you do with it?4. How do I get rid of a person? Place the element 05. Indicates the current or the number of people? Define the variable number;6. Because of the number of uncertain cycles, cycle conditions with Whlie numbers > 17. How to cycle off? If i = 13, go to the first person to continue the count.The code is as follows: int arr[13] ={1, 2, 3, 4, 5, 6, 7, 8, 9, ten, one, a. int count = 0, number = 13,

standard weightNote:The meaning of the standard body weight: Height-weight (kg) and 100 (110) Subtract, the difference is more than 3 is thin, less than 3 is overweight, between 3 and 3 is the standard.

title: There is an int array with several numbers in it. How many different numbers are required to be counted? How often are each number appearing? The array is arranged from less to more frequency, the same frequency is from small to large. Workaround: Use an array to store different numbers and occurrence probabilities, compare the numbers in each group with the other numbers in the group, and set the same one to NULL, as well as the number of occurrences of the numbers plus 1, and finally us

EXP9 the basic practice of Web security Fundamentals Answer 1, SQL injection attack principle, how to defend?1.对用户的输入进行校验，可以通过正则表达式，双"-"进行转换等。2.不要使用动态拼装sql，可以使用参数化的sql或者直接使用存储过程进行数据查询存取。3.不要使用管理员权限的数据库连接，为每个应用使用单独的权限有限的数据库连接。4.不要把机密信息直接存放，加密或者hash掉密码和敏感的信息。5.应用的异常信息应该给出尽可能少的提示。6.采取辅助软件或网站平台来检测sql注入。2, how to defend the principle of XSS attack?在表单提交或者url参数传递前，对需要的参数进行过滤；检查用户输入的内容中是否有非法内容，如尖括号、引号等，严格控制输出。3, C

script in the user's browser to obtain information such as its cookie. Instead, CSRF is borrowing the user's identity to send a request to Web server because the request is not intended by the user, so it is called "cross-site request forgery". For the defense of CSRF can also start from the following aspects: through the Referer, token or verification code to detect user submissions; Try not to expose the user's privacy information in the link of the page, for the user to modify the dele
