Strings: A string in C++ is a sequence of characters. It is a data type that is used to store text. Strings are declared using the string keyword. 
Strings can be concatenated using the + operator. 
Strings can be compared using the ==, !=, <, >, <=, and >= operators. 

Streams: A stream in C++ is a sequence of characters that can be read from or written to. Streams are used to input and output data. There are two types of streams in C++: input streams and output streams.
Input streams are used to read data from a source, such as a keyboard or a file. Output streams are used to write data to a destination, such as a screen or a file.
The cin object is an input stream that is used to read data from the keyboard. The cout object is an output stream that is used to write data to the screen.

Numerics: Numerics in C++ are data types that are used to store numbers. The most common numeric data types in C++ are int, float, and double.
The int data type is used to store integers. Integers are whole numbers, such as 1, 2, and 3.
The float data type is used to store floating-point numbers. Floating-point numbers are numbers that have a decimal point, such as 3.14 and 2.718.
The double data type is used to store double-precision floating-point numbers. Double-precision floating-point numbers are more precise than floating-point numbers.

Numeric variables can be used in arithmetic expressions. 

String Streams: A string stream in C++ is a stream that is associated with a string object. String streams can be used to read from and write to strings.
To use a string stream, you must first include the sstream header file. Then, you can create a string stream object by passing a string object to the stringstream constructor.

Once you have created a string stream object, you can use the << and >> operators to read from and write to the string stream.
String streams can be used to perform a variety of operations on strings, such as parsing strings, converting strings to numbers, and vice.
