Temperature Unit Conversion

#include <iostream>
using namespace std;
 
// Write your code here
float readTemp(int raw){
    //Covert the Raw value to Celsius
    return (raw/10.0);
}

float readTemp(int raw, char uint){
    
    raw = raw*0.1f;

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