hello, havent covered getchar$()$ and EOF codes yet and have to substitute getchar$()$ to scanf but cant did. how can rewrite while part without ruin whole code? how can we take an input of binary with integer? because if we input $010$ in an integer, then it will be stored as $10$ and not $010,$ same goes with any input which stars with $0$ for eg$.000,001,010,011$
