Which checks the object code to determine whether there are more efficient means of execution?
1)Interpreter
2) Linker
3)Compiler
4) Optimizer 21. you have three dice each side is numbered as 1,2,3,4,5,6 .you have to take a
number from user check that number as sum of any side number of these
three dice.like we take number as 5 then the possibility are (1,1,3) (1,2,2)
(1,3,1) (2,1,2) (2,2,1) (3,1,1) and is 6 possibility. So write to a program for that.
