Chewacca and number doubt

#1

#include
using namespace std;
int main() {
char a[50];
cin>>a;
int i=0;
if(a[i]==‘9’)
{i++;}
for(;a[i]!=’\0’;i++)
{
int dig =a[i]-‘0’;
if(dig>4)
dig=9-dig;
a[i]=dig+‘0’;
}
cout<<a;
return 0;
}
will using cin>>a work???
since we are inputting the no without spaces wont it b stored in a[0]?
