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 F;

    F = 0;

    if(unit == 'C') return raw/10;

    else if(unit == 'F') F = raw/10 * 1.8 + 32;

    return F;

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