The two temperature scales used in the United States are Celsius and Fahrenheit. The mathematical relationship between the two scales is: 5 C=(F - 32) Write two functions, fToC and cToF, which convert temperatures from one scale to another. For example, a call offToC will return the equivalent Celsius temperature for a given Fahrenheit temperature. Celsius = f[oC (100); // Celsius now stores 37.8 6.
