Question

Write a C program (intro level) that calculate car emmisions

4.2 Car emissions Gas-powered cars emit various types of pollutants: 1. Carbon monoxide (CO), an odorless and colorless gas that is highly poisonous if breathed by humans. 2. Hydrocarbons (HC), burned or partially burned raw fuel, which are a major contributor to smog. 3. Nitrogen oxides (NOx), which is generated when nitrogen in the air reacts with oxygen at the high temperature and pressure inside the engine. 4. Non-methane hydrocarbons (NMHC), the part of the hydrocarbons that doesn't include methane emissions In an effort to fight the emissions of such pollutants in the atmosphere, the city of Davis wants to enforce emissions caps for cars. Since cars tend to exhibit different properties, whether they relatively new (i.e. less than or equal to 50,000 miles) or old, the city defined the following table: Limit for old car 4.2 grams/mile 0.39 grams/mile 0.5 grams/mile 0.31 grams/mile Pollutant number CO HC NOx NMHC Limit for new car 3.4 grams/mile 0.31 grams/mile 0.4 grams/mild 0.25 grams/mile 4
