Temperature Unit Conversion

#include <iostream>
using namespace std;
 
// Write your code here

float readTemp(int raw)
{
    return raw / 10  ; 
}

float readTemp(int raw , char unit)
{
    if (unit == 'F') return (raw/10)* 1.8 + 32 ; 
    else return raw / 10 ; 
}
 
int main() {
    int raw;
    char unit;
    cin >> raw >> unit;
 
    if (unit == 'D') {
        cout << readTemp(raw);
    } else {
        cout << readTemp(raw, unit);
    }
 
    return 0;
}
