Answer:
InsuranceRates.smokerCharge
Explanation:
To set the baseCost variable to the value of the class variable smokerCharge, the developer needs to replace
Decimal baseCost = XXX;
with
Decimal baseCost = InsuranceRates.smokerCharge;
This is done using the class reference type.
The smokerCharge should be declared in the InsuranceRates class, at first.
For example Ball b;
And then, a new instance of the object from the class is created, using the new keyword along with the class name: b = new Ball();
In comparing to the example I gave in the previous paragraph, the object reference in the program is:
InsuranceRates rates = new InsuranceRates();
Because the smokerCharge is coming from a different class, it can only be assigned to the variable baseCost via the InsuranceRates class to give:
Decimal baseCost = InsuranceRates.smokerCharge;
Answer:
if ((b*b - 4*a*c)<0)
cout << "no real solutions";
return;
Explanation:
To check if "b squared" – 4ac is negative, we use the expression if ((b*b - 4*a*c)<0). This expression evaluates the 'bsquared' and substracts '4ac' from it. It then compares the resulting value with zero. if it is less than zero it means it is a negative number, so it executes the statement following cout << "no real solutions"; and returns
Ping means how much of a delay there is in your connection. The lower the ping, the smaller the delay. This plays an important role in online gaming. If your ping is 350, then your delay is 350ths of a second.
