My cpp program is not being asking for input.

Question

i have come across this question and could not get why it is not asking for input. output of the code is cin0. please explain it why so.

#include

        

Answer 1

Shadowing.

int cin;
cin >> cin;

Both cin in the second line refer to the int, not the class you're used to. You're calculation a>>a (ie. roughly equivalent to a / 2^a), just with a variable called cin.

Choose another variable name.
