can someone help me whys it saying winamt not declared and
randnum not declared?/
Solution
The winamt and randnum assigend direct to the function calls
which are declared as globally. when the global function starts
it's execution the life span of the variables available through
out the program. But here we declare winamt and randamt with
in the function. Here these two variables available only with in
that block.these two variables doesn't available through out the
program. Hence it shows compilation error these two are not
