Study Notes

Overview of C/C++ Concepts: Core Programming Constructs

C++ is a superset of the C language, and learning C++ implies learning C.
C++ is designed to be easily compiled to assembly and then to machine code, allowing for maximum flexibility to tap into the power of the CPU.
C++ is the fastest high-level language around today, and is very mature and standardized.
C++ is more portable and interoperable than Java or Python, with thousands of libraries and tools available.
Java is an indirect derivative of C/C++, with most of the syntax and semantics being similar.
C++ supports a variety of programming paradigms, including imperative, declarative, functional, generic, metaprogramming, and parallel programming.
A C++ program consists of a collection of interacting functions and methods, with every program requiring a main() function.
Many standard operations are performed using C++ libraries, which are imported into a program by including suitable header files.
C++ primitive data types are similar to their Java counterparts, with 2's complement used for their representation.
C++ provides a bool data type similar to Java's boolean data type, with reserved words true and false for boolean constants.
C++ provides a string object similar to Java's String class, with the most appropriate class being std::wstring.
Mathematical expressions and operators are identical in C++ and Java, with rules of precedence, data type promotion, and type casting being identical.C++ Programming Fundamentals
C++ determines the data type of an expression based on the largest entity in the expression.
Precedence plays a role in determining the data type of an expression.
Standard input in C++ is performed via the standard input stream, std::cin, typically tied to keyboard input.
Conditional statements in C++ use standard syntax for if...else statements.
Ternary operator (?:) provides a shortcut for conditional expressions in C++.
C++ provides operators for std::string comparison as if they were numbers.
The switch statement in C++ is similar to Java and can be used only with primitive types.
Looping constructs in C++ are similar to C and Java, but all loop variables must be predefined.
Loops and conditional statements in C++ can be nested within each other indefinitely.
Functions and methods in C++ are similar to methods in Java and are used to perform specific tasks.
Parameters to functions in C++ must be defined, and primitive types are typically passed by value, while complex data types are passed by reference.
Functions and methods in C++ can call each other to accomplish recursion, and function prototypes are used for recursive functions and methods.
