First 5 Modules of C++20 Fundamental by Paul Deitel.
- Preprocessor: Used for processing directives before actual compilation. e.g.,
#include. - Object File: Compiled but not linked code snippet.
- Garbage Value: Uninitialized variable holding random data.
- println: Will be added in C++23 for easier printing.
length()starts_with()ends_with(): String functions for string manipulation.setprecision: Manipulator to set the precision of floating-point numbers. (iomanip)fixedandscientific: Manipulators to set the output format of floating-point numbers. (iostream)formatheader: For advanced output formatting. Example usage::>20.2f.[[fallthrough]];: Indicates intentional fall-through in switch cases.using enum: Allows scoped enums to be used without prefix.inlinekeyword: Recommends to declare small and time-sensitive functions as inline.boolalpha: Manipulator that returns values as true/false instead of 1/0. (iostream)statickeyword: Used to declare variables that retain their values between function calls.default argument values: Typically specified in headers to maintain consistency.- Narrowing Conversion: Causes compilation errors; e.g.,
int x{12.0}. <numbers>header: Provides mathematical constants.
- Boost Library: Uses types like
cpp_intanddec_float_50for precise calculations. - Banker Rounding: A rounding strategy used in financial calculations.
- Go-style Conditional:
if(command; condition)for cleaner control flow. - Use single quotes on numbers: Enhances readability, e.g.,
1'000'000. - Block for scoping
{}: Encourages declaring variables in the minimal necessary scope.
- Open-std.org: Official site for C++ standards.
- CppCoreGuidelines: Guidelines for C++ programming.
- cppreference.com: Specifically the headers section for detailed library information.
- Awesome C++: A curated list of awesome C++ frameworks, libraries, etc.
