char to int

[Flamer]

i'm doin an ifstream .get() to pull in characters from a text file.
and the last character it pulls out a number. I want to return an int value.

Heres the code maybe i'm doing something wrong..

int get_version_num()
{
ifstream din;
do
{
din.get(ltr);
cout<< ltr;
if(ltr=='V')
qans++;
if(ltr=='R')
qans++;
if(ltr=='M')
qans++;
}
while(qans<4);

do
{
din.get(ltr);
i++;
}
while(i<5);

answ = ltr;
return ltr;
}
