Continue to review the list of knowledge points, this chapter contains a list of added, deleted, judged whether it is empty, and the list length, as well as the list of linked lists a few knowledge points1. Whether the list is empty1. Determine if

V. Pointers:5.1. The pointer is also a variable that has all the properties owned by all variables.5.2, for accessing storage space.5.2.1, access to storage spaces using variable names is more secure than access to pointers.5.2.2, we use pointers

Background: Sometimes the code will put the content to run in the main thread running, but assume that the main thread inside the code calls Dispatch_async occasionally appear crash, so it is necessary to infer whether it is already in the main

Number of occurrences of the number in the sorted array.Counts the number of occurrences of a number in a sorted array. For example: Sort array {1,2,3,3,3,3,4,5} and number 3, because 3 appears 4 times, so output 4. #include int one_num_times (int

Article 1 Data abstractionThe purpose of an abstract data type is to extend the language into a specific problem area. The general definition of an abstract data type requires that the following steps be trained:1. Take a descriptive name for the

There are many queues in the life of the shadow, such as playing rice queue, buy train tickets queue problems, can be said with time-related issues, generally involved in the queue problem; from life, you can abstract the concept of the queue, the

1 What is an array? An array is a data structure that contains multiple elements of the same data type.2 declaration of an array?int [] Num; Note: when declaring an array, square brackets ([]) must follow the type, not after the variable name. In C

A program is essentially composed of BSS, data, and text segments three. This concept is very important in the current computer programming, and it is very important in the design of the embedded system, which involves the memory size allocation

1, the advantages of the generic typeIn daily development, we often develop some special functions, and this function is suitable for many types (such as string,int, etc.), the simplest way is to do a implementation for each type, the disadvantage
