stoppingDistance = speed * (2.25 + speed / 21)Write a program which determines whether a vehicle’s tailgating distance is safe.The program should read in the speed of the vehicle and the vehicle’s tailgatingdistance. The program should then calculate the distance that would be required tostop the vehicle.If the stopping distance is less than the tailgating distance, your programshould print “No problem.” If the stopping distance equals the tailgatingdistance, your program should print “Minor wreck.” If the stopping distanceis greater than the tailgating distance, your program should print “Majorwreck!”Notice that the expression on the right side of the formula above will force thecompiler to convert everything to type double. Use type double for your workingvariables. Write your program so that it is able to produce the following screendisplay:Sample session:Enter your speed (in mph): 60.0Enter your tailgate distance (in feet): 240.0Major wreck!
4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }
