Today, I took a moment to think about the problem of using double pointers for parameter passing. I used to only know what to use, but I have never thought about why. Today is just a bit xian.# Include "stdio. h" Void fun (char * pa){Printf ("pa value: % d \ n", pa );Pa = "bb ";Printf ("

; the while(Fast! =slow) { +Fast = Fast->Next; -slow = slow->Next; $ } $ returnfast; - } -};There is another solution to this problem, which uses geometric distance relations, we can quickly find the intersection point as long as the difference d of the distance between the two linked list and the intersection point. When we traverse the short-length linked list, the long linked list accesses only the end of the record at the distance of D. We can design the algorith

Training at various levels within each company is not reviewed here, becauseThe level of system application and training varies widely among companies. Here is a brief summary of SAP's official standard course training and PA consultancy training. The SAP official training mentioned here does not meanIt is a training provided by SAP and also a cooperative training institution recognized by SAP. Especially since the beginning of this year, sap has hand

See http://community.csdn.net/Expert/topic/3662/3662366.xml? Temp =. 1618006 there is a post about the excitement.The specific question is what is the macro function, # define macro1 (T, m) (INT) (void *) (T *) 0-> m ). Is to get the offset of T (structure or class) member m in the structure (or class. However, many people cannot understand (T *) 0-> M. I will analyze it. First write a program segment:# Pragma pack (1)Typedef struct {Char;Int B;};# Pragma pack () # Define macro1 (T, m) (INT) (v

1. Cost Accounting and account-based Profit Analysis and Comparison CO-PA module has two kinds of profit analysis, based on account and cost-based profit analysis, the relationship between the two and the difference, what are the advantages and disadvantages? A.Costing-base uses value field, which can correspond to cost/revenue cost elements, MM | SD condition types, or product cost components, while accounting-based uses cost elements. B. in terms of

Description and use of array pointer variables The pointer variable that points to an array is called an array pointer variable. Before we discuss the description and use of array pointer variables, let's clarify a few relationships.An array is made up of contiguous blocks of memory. The array name is the first address of the contiguous memory unit. An array is also made up of individual array elements (subscript variables). Each array element occupies several contiguous units of memory, depend

the figure6.3we can see that there are the following relationships:PA,A,AMP;A[0]all point to the same cell, which is an arrayaThe first address, also0number ElementA[0]'s first address. Pa+1,a+1,a[1]all point to1number ElementA[1]. AnalogyA+i,a+i,a[i]PointingInumber ElementA[i]. It should be stated thatPAis a variable, andA,a[i]are constants. Should be noted when programming. Main () {int a[5],i;for (i=0;i{a[i]=i;printf ("a[%d]=%d/n", I,a[i]); }print

This topic is easier, my idea is to compare the length of the two list, we have to find the intersection is not possible for the long chain of the front of the long part of the list,So to compare the shorter part of the twoWrite a program to find the node at which the intersection of the singly linked lists begins.For example, the following, linked lists:A: a1→a2 c1→c2→c3 B: b1→b2→b3Begin to intersect at node C1.No

This algorithm involves an important mathematical conclusion: if a[k/2-1]The more general conclusion is: K=PA+PB, if a[pa-1]The algorithm idea is as follows:1, assume that a length is m,b length of n,m>n, and vice versa.2, Split K=PA+PB.3, if A[PA-1]4, the boundary condition of recursion is if m=0, return b[k-1], if k
