C++ Program For Converting Temperature Celsius Into Fahrenheit

#include <iostream>
using namespace std;
int main() {
    float fahren, celsius;
    cout << "Enter the temperature in celsius\n";
    cin >> celsius;
    // convert celsius to fahreneheit
    // Multiply by 9, then divide by 5, then add 32
    fahren =(9.0/5.0) * celsius + 32;
    cout << celsius <<"Centigrade is equal to " << fahren <<"Fahrenheit";
    return 0;
}
