data types in programming: a comprehensive geeksforgeeks style tutorial
data types are fundamental building blocks in any programming language. they classify the kind of values a variable can hold and dictate the operations that can be performed on it. understanding data types is crucial for writing efficient and error-free code. this tutorial provides a comprehensive overview of various data types, categorized by their nature, along with illustrative examples in python and c++.
*i. fundamental data types:*
these are the most basic data types provided directly by programming languages. they represent individual values.
*a. numeric types:*
1. *integers (int):* represent whole numbers without any fractional part. they can be positive, negative, or zero.
*python:*
*c++:*
2. *floating-point numbers (float, double):* represent numbers with fractional parts. `float` usually uses 32 bits, while `double` (double-precision) uses 64 bits, offering greater precision.
*python:*
*c++:*
3. *complex numbers (complex):* represent numbers with a real and an imaginary part (e.g., 3 + 2j).
*python:*
*c++:* c++ uses `std::complex` from the `complex` header.
*b. character types (char):*
represent single characters, usually enclosed in single quotes. they are often represented using ascii or unicode encoding.
*python:* python treats `char` as a string of length 1.
*c++:*
*c. boolean types (bool):*
represent truth values: `true` or `false`.
*python:*
*c++:*
*ii. composite data types:*
these data types group together multiple values of potentially different types.
*a. arrays (in c++):*
arrays store a fixed-size sequence of elements of the same data type.
*c++:*
*python:* python uses lists (dynamically sized) instead of fixed-size arrays.
*b. lists (in python):*
lists are ordered, mutable ( ...
