+Write a program to make a simple calculator. The program should perform four basic operations (1-addition, 2-subtraction, 3-multiplication, and 4-division) 
+depending on the user’s choice. 
+The program will take two values from the user and the type of operation. The result will be displayed based on the operation chosen by the user. 
+The program will be repeated until user requests to stop.
