So count (key) returns the number of elements of the key, and find (key) returns the first function of the key.Here is a simple example of applying a map container: Reading a file, recording the number of occurrences of each word in the file, and outputting the occurrences of the word and the number of occurrences in dictionar

Here are the notes I made after reading the 6th edition of C + + Primer Plus, as a memo to facilitate review later.Notes section Why is C + + const better than C # # #? First, it can explicitly specify a type and have type checking capabilities.Second, you can restrict a definition to a specific function or file by using a scope rule for C + +.Third, you can use the const for more complex ty

sequence block enclosed in curly braces. The try block is followed by one or more catch clauses. Each catch clause consists of three parts: a keyword catch, a single type in parentheses, or a declaration of a single object-called an exception specifier, and a block of statements that is usually enclosed in curly braces. If a catch clause is selected to handle the exception, the associated block statement is executed. Once the catch clause finishes executing, the program process proceeds immedia

Record some of the things you read about this book.I. References (reference)The reference has a different name for the object. For example:int ival=1024;int relval1=ival;//to, attention try not to use this way:int relval=ival;int relval2;//error, reference must be initializedWhen a reference is defined, the program binds the reference with its initial value (binding) instead of copying the initial value to the reference. Once the initialization is complete, the reference will always be bound tog

If Trunc mode is specified when the file is opened, the file is also emptied, regardless of whether in mode is specified at the same time.4.2.2 Mode is a property of a file rather than a streamNote: Whenever you call the Open function, set the file mode, which can be either explicit or implicit.
