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){
    float ans;
    
    ans = raw/10;
    
    if(unit=='F'){
        ans=ans * 1.8 +32;
    }

    return ans;

}
int main() {
    int raw;
    char unit;
    cin >> raw >> unit;
 
    if (unit == 'D') {
        cout << readTemp(raw);
    } else {
        cout << readTemp(raw, unit);
    }
 
    return 0;
}
