CMSC 140 midterm Questions and Answers(A+ Solution guide)

CMSC 140 midterm
Code the following statements using combined assignment operators:
1. price1 is equal to price1 plus 5.
2. price2 is equal to price2 times 7.0
3. price3 is equal to price3 divided by 4.5
4. totalPrice is equal to totalPrice modulus 3

Hint: Things like an equal sign or multiply sign but initialize the variables. - ✔️✔️double
price1 = 3.45, price2 = 5.79, price3 = 15.64;
int totalPrice = 98;

//1.
price1 += 5;
//2.
price2 *= 7.0;
//3.
price3 /= 4.5;
//4.
totalPrice %= 3;

What does the following code output to the user?


int A = 10, B = 17, C = 2;
double D = 17.01;
bool boolValue = true;

if (A > B)
{
cout << "Good afternoon, sir." << endl;
if (A == C)
{
cout << "Fine weather today we're having." << endl;
}
}
else if (D < B)
{
cout << "It looks like it will rain later on." << endl;
}
else
{
cout << "Good morning." << endl;

, if (boolValue == true)
{
cout << "The sun's bright at this time." << endl;
}
else
{
cout << "We've got a lot of cloud cover now." << endl;
}
} - ✔️✔️//The code outputs:
//Good morning.
//The sun's bright at this time.
