In front of the content of the study to do some fine analysis, not from the overall summary, this blog will be the knowledge of the previous study to do a general understanding.Mind MappingThe overall study of C language is shown in the front.Data

Introduction to a printf functionThe printf function is a standard library function that can output the results of a program operation in an exact format.The printf function is called in the following format:printf ("Format control string", output

The basic concept of a variable1. What is a variable?　　It represents the memory of a space, its value can be changed, is the basic unit of data.2. Variable composition:Variable name and variable type.3. Variable classificationGlobal variables:

PhenomenonHalcon the exported C + + program, the Try catch is not the exception. You can catch to an exception normally under Halcon. C + + code:Try{Tuple_max (Hv_length, &hv_max);//There is a problem here, there will be an exception, but the

C language is a structured programming language, it is process-oriented, but we can use some small tricks to implement object-oriented features. This blog post will explain how to use the C language for polymorphism using an example.Define

Problem description gives you two collections that require {A} + {B}.Note: There will not be two identical elements in the same collection. Input data for each group is divided into three rows, and the first row has two digits n,m (01 212 31) 211

staticHave a very simple logic to it. If A variable static is, it means it's a global variable, but it's scope is limited to where it's defined (i.e. only Visible there). For example: Outside a Function:global variable but visible only
