We aren't going to do the assignment for you, not even parts of it. Tell us what you are stuggling with and we will do our best to provide examples that you can use to finish it yourself

Well, as stated before I already have done this assignment but the area that I was having the most trouble with was in calculating the upgrades and having the compiler be able to increment and decrement by user input.
What I was told was using a for statement that looked something like this :

while (upgradeSelection != 8 && upgradeSelection =! 7 )

upgradeCost = 0;

for (int E = 1; E <= engineLevel; E++)
upgradeCost = upgradeCost + 100 * E;

for (int T = 1; T <= tireLevel; T++)
upgradeCost = upgradeCost + 100 * T; etc....

it continues to go into a switch
for each input for each upgrade
