Explain, line$-$by$-$line the errors in and rewrite correctly the following code:

a $=$ input$($ Please entere a $)$

b $=$ input$($ Please enter b $)$

a $=$ Input $$ Please enter c $$

v$1=$ a$+$ B$+$d

v$2=$ a$/(($b$+$c$)($c$+$a$)$

v$3=$ a$/$b$*$c

print$($ a $+$ b $+$ c$=$ v$1])$

print $([$v$2=$ v$2]$

print $([$v$3=($v$4)])$
