After calling a "calcMPG$()"$ function once for each car, have main determine and display which car was the most fuel$-$efficient and how many miles per gallon it got. The "calcMPG$()"$ function should be passed the distance driven and the gallons of gas used as arguments, and should return the miles per gallon obtained.
