Code is not converting uppercase letter to lowercase when preceeded by a vowel

Codeforces Problem-

When I give an input of uppercase preceeded by a vowel ,it is not converting the uppercase letter into lowercase e-g-Input-aBAcAba output-.B.c.b

int main() 
{
    int i;
    locale loc;
    string a;
    cin>>a;
    for(i=0;i<a.size();i++)
    {
        if(isupper(a[i]))
            a[i]=tolower(a[i]);
        if(a[i]=='a'||a[i]=='e'||a[i]=='i'||a[i]=='o'||a[i]=='u')
        {
            a.erase(a.begin()+i);
        }
        if(a[i]=='a'||a[i]=='e'||a[i]=='i'||a[i]=='o'||a[i]=='u')
            i--;
    }
    for(i=0;i<a.size();i++)
        cout<<'.'<<a[i];
    return 0;
}

 if(a[i]=='a'||a[i]=='e'||a[i]=='i'||a[i]=='o'||a[i]=='u')
 i--;

This doesn't work, because you have already erased the vowel from a, so the decrement doesn't happen and you skip the next character.

You might instead want to do 

if (condition)
   a.erase(...);
else
   ++i;

and remove the increment from the for-statement.
