/*C++ Program that contains four user defined function(s) addition(), subtraction(),
division(), multiplication(). Develop a calculator as follows:
• In main() function:
o A menu with choices addition,subtraction,division and multiplication must be
displayed.
o Get two numbers and a choice from user o Call the respective functions with
user given number as parameter using switch statement
o Print the result from addition(), subtraction, division(), multiplication().
• In user defined functions:
o Plus and Minus function get two interger values and return interger.
o Multiply and Divide functions get two interge values and return float.*/
