int main()
{
    float f = 1.0, c;
     
    c = (f - 32) / 1.8;
 
    std::cout <<  std::fixed << std::setprecision(2) << f << " Fahrenheit = " << 
                  std::fixed << std::setprecision(2) << c  << " celsius" << "\n";

Answer 3

#include <iostream>
 
int main() {
     
 int fahrenheit = 96;
       
    double celsius = (fahrenheit - 32) * 5 / 9.0;
       
    std::cout << "Celsius = " << celsius;
}
   
   
   
   
/*
run:
     
Celsius = 35.5556
    
*/
