RPn algorithm and easy calculator

Edsger Dijkstra algorithm for Reverse Polish notation (Postfix notation).

Implemented basic operations such as

• a plus (+)
• minus (-)
• multiplication (*)
• division (/)
• exponentiation (^)

Compilation and launch

Just use the g++ compiler

$ g++ code.cpp -o app.out
$ ./app.out

About RPn

Reverse Polish notation (RPN), also known as Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to Polish notation (PN), in which operators precede their operands.

• Example:

infix:  ((15 ÷ (7 − (1 + 1))) × 3) − (2 + (1 + 1))
postfix: 15 7 1 1 + − ÷ 3 × 2 1 1 + + −
