C++ Character Set More Solved Programs
Before writing programs in C++, let us first understand its fundamental concepts. This chapter
introduces the basic concepts of C++, including the character set and tokens used in C++
programming.
C++ CHARACTER SET
A character set refers to the letters, digits and special symbols that can be used to write programs
in the C++ language. These are:
Characters Uses
Letters A–Z or a–z
Digits 0–9
Special symbols ~ ‘ ‘ ! @ # $ % ^ & ( ) * - _ + = : \ ] { } ; " < > , ? | `
Tokens in C++
Tokens are the smallest individual units of a C++ program. They are classified into the following
categories:
Keywords Data Types Variables
Constants Delimiters Operators
Let us explore each of these in detail.
Keywords
Keywords are special words in C++ that have a fixed meaning and cannot be used as variable
names. They help the computer understand what actions to perform. In C++, keywords are
case-sensitive.
