The program has the following functionality: 1. Selection of temperature and strength: The user can select the temperature from -20.0°C to 30.0°C in 0.1°C increments and the strength from 96.00% to 97.00% in 0.01% increments. 2. Entering the amount without water alcohol (dal) or water alcohol (dal): The user can enter the amount without water alcohol (dal) or the amount of water alcohol (dal) to determine the volume of ethyl alcohol at +20°C.
