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)
{
    switch(unit)
    {
        case('C'):
        {
            return raw/10;
            break;
        }

        case('F'):
        {
            return (raw/10)*1.8 + 32;
            break;
        }

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