C++ is a statically typed, compiled, general-purpose, case-sensitive, irregular programming language that supports procedural programming, object-oriented programming and generic programming.
C++ is considered a mid-level language that combines the features of high-level and low-level languages.
C++ was designed and developed by Bjarne Stroustrup in 1979 at Bell Laboratories in Murray Hill, New Jersey. C++ further extended and improved the C language, originally named C with classes and later renamed C++ in 1983.
C++ is a superset of C. In fact, any legal C program is a legal C++ program.
C++ constants syntax
Constant values are fixed values that do not change during program execution. These fixed values are also called literals.
Constants can be any basic data type, which can be divided into integers, floating-point numbers, characters, strings and Boolean values.
Constants are like regular variables, except that the value of a constant cannot be modified after it is defined.
C++ constants example
#include <iostream>
using namespace std;
int main(){
cout << "Hello\tWorld\n\n"; return 0;}
