Information such as "Memory access violation" or "segmentation violation" usually means that a pointer variable contains a pseudo-address. One common reason is that initializing a variable fails.The result of free (p) is that the address to which P is pointing does not change, but the data at that address is undefined at this time.Occasionally, when your program uses a lot of space, the system may not meet your requirements for the new unit. A null po

training school, in the first two months I again "C Primer Plus" gnawing down. In this way, my programming is a real starter.At that time I knew that there is a discipline such as data structure, but also heard that the subject is very important, but I do not know why it is important, and even think that learning seems to be no use. So then we learned C #, and began to learn to drag the control. After that, I started looking for a job.Finally, this y

This part of the content from HTTP://WWW.CNBLOGS.COM/MINGC, the author is only used to organize learning.Problem Description: Write a program to solve the selection problem. Make K=N/2. Draw a table showing how long your program will run when n is a different value.Understanding: There is a set of n number to determine the largest of the K, called the Choice Problem (selection problem)Idea: Read the pre-K number to the TEMP array tmp (and sort in descending order). Then read the subsequent numbe

A brief discussion on the recursion of data structure and algorithm analysis

the direction of the resulting baseline case.(3) Design rules.Assume that all recursive calls can be run. This is an important rule because it means that when designing a recursive program, it is generally not necessary to know the details of the overhead management, and the computer can work out the complex details without having to trace a large number of recursive calls to the view.(4) The principle of synthetic benefit.Do not perform repetitive work in different recursive invocations when s

Data Mining algorithm: Correlation analysis One (basic concept)

methods of Mining association rules is to calculate the support and confidence of each possible rule, but at a high cost. Therefore, the method of high performance is to split the support degree and confidence level. Because the degree of support for a rule relies primarily onx∪y , so most association rule mining algorithms typically employ a strategy that is decomposed into two steps:   frequent itemsets are created with the goal of discovering all itemsets that meet the minimum support th
