Functions 7. Write a program that contains two functions with the following prototypes float convert_mpg to_ipk (float miles_per_gallon) /this function receives a float type argument called miles_per gallon, and converts is to a new float variable called liters_per_km as follows: liters per km1.o/( miles per gallon 3.78541 /* gallons/liters */ * 0.621371 /* km/miles */) It then returns this newly calculated value float convert lpk to mpg (float liters per_km) / this function receives a float type argument called iters_perkm, and converts is to a new float variable called miles_per gallon as follows: miles per gallon-(1.0/liters per km) 0.264172 liters/gallons1.60934 /km/miles It then returns this newly calculated value
