Reading Notes: C ++ cookbook

This book is not intended for beginners. This book mainly explains how to use some ready-made class libraries, including the C ++ standard library and boost library.

Chapter 4 Create a c ++ Application

1. Compile, Link, static/dynamic library

2. Compiler

3. GNU Compiler set (GCC)

4. Visual C ++

5. Intel Compiler

6. metrowerks Compiler

7. Borland Compiler

8. comeau Compiler

9. Digital Mars Compiler

10. cygwin and mingw

11. Compile the link command

12. Dynamic Link Library

Chapter 4 code structure

2.2 ensure that only one instance exists in a variable that spans multiple source files.

Use extern

2.3 use the forward class Declaration to reduce # Use of include

Using the forward class declaration can reduce compilation dependencies and use the Forward Declaration to create a simple name. Any class in this header file can reference this name. The linker can match the name used in the header file to implement the definition in the file.

2.4 use namespaces to prevent name conflicts

2.5 contains an inline File

Create. the INL file and use # include at the end of your header file to include it. This function is equivalent to placing the function definition at the end of the header file, however, this can separate your declarations and definitions.

Chapter 2 Numerical Calculation

3.1 convert a string to a numeric value

You can use the lexical_cast class of the standard library or boost library.

The strtol function in the standard library can be implemented.

3.2 convert a value to a string

You can use the stringstream class in the standard library to store strings.

The format class in the boost library can also implement this

3.3 test whether the string contains valid values

Use the lexical_cast function template of the boost library to test valid values. This method can contain a minus sign or a plus sign, but cannot contain spaces.

3.5 parse a string containing values expressed in scientific notation

The most direct way to solve this problem is to use the stringstream class in the standard library.

3.6 conversion between different numeric types

Overflow is the most common problem in conversions between different types of values. Use the numeric_cast class template of the boost library for runtime detection. If overflow or underflow occurs, a bad_numeric_cast type exception is thrown.

Chapter 2 string and text

4.1 fill string

The append and insert functions of the string class can be filled with multiple characters.

4.2 crop a string

Erase Functions

4.5 flip string

You can use the reverse function in the standard library.

4.6 split string

Use the find function in the standard library to find the delimiters, and then obtain the corresponding strings.

4.9 search strings

4.10 search for the nth substring

4.11 delete a substring from a string

4.12 convert string to lowercase or uppercase

4.13 case-insensitive string comparison

4.14 case-insensitive string SEARCH

4.15 convert tabs and spaces in text files

4.16 line feed in text files

4.17 calculate the number of characters, number of words, and number of lines in a text file

4.18 calculate the number of occurrences of each word in a text file

4.19 add blank content to text files

4.20 adjust text files

4.21 compress multiple spaces in a text file into one

4.22 automatically correct text

4.23 read text files separated by commas

4.24 use regular expressions to separate strings

You need to use the RegEx library in boost. Note that you need to specify the library to be loaded during compilation.
