I need help writing a code in math lab

Vector Operations Create ONE well-documented main program or Driver that will call three user-defined functions to solve the problems below. Burning one gallon of gasoline in your car produces 19.4 pounds of CO_2. Calculate the amount of CO_2 emitted during a year for the following vehicles, assuming they all travel 12,000 miles per year. The reported fuel efficiency numbers were extracted from the manufacturers' websites based on the Environmental Protection Agency 2010 criteria; they are an average of the city and highway estimates. Create a user-defined function with fuel efficiency as an input vector and the amount of CO_2 emitted as the output vector. Suppress all intermediate computations using the semicolon operator
