data types

In C++, the representation of integers as either int or char reflects the flexibility of programming languages rather than strict mathematical definitions.

int is a fundamental data type used to represent integers (whole numbers without fractional components).

It is used to store signed integer values (both positive and negative numbers).

An unsigned integer can only store non-negative values (zero and positive numbers).

In C++, both float and double are used for representing floating-point (real) numbers, but they differ primarily in precision and memory usage.

Scientific notation is a way of expressing very large or very small numbers in a simplified format, making them easier to work with, especially in mathematical and scientific calculations. It uses powers of ten to represent numbers.

In C++, \n is an escape sequence that represents a newline character.

The sequence 0\ in C++ doesn't have a specific, standard meaning on its own and may result in syntax errors if used improperly.

\0 signifies a null character, often used for marking the end of strings in low-level programming.

<cstdint>is a standard header file in C++ that provides fixed-width integer types and limits from the C standard library (stdint.h).

In C++, bool is a built-in data type used to represent boolean values, which can only be either true or false.

True: 1; False: 0
