Question
1) Given w = 13 , x = 10 , y = 26, and z = 3 , and all are declared as int ,
1) Given w = 13, x = 10, y = 26, and z = 3, and all are declared as int, what is the value of result for each line of code below? result = (x / y) * z; __________ result = w % z; __________ result = w + 5 * z; __________
a) 1.154 4 54
b) 1 8 37
c) 0 1 28
2) Choose what is stored in players when the string George Moore, Nicky Bittner, Sarah Cynthia Sylvia Stout is entered on the keyboard: string players; cout << Enter names of players << endl; cin >> players;
a) George Moore
b) George Moore, Nicky Bittner, Sarah Cynthia Sylvia Stout
c) Nothing you can't read string with cin
d) George
3) If my number is 87 and my name is Sidney Crosby what will display?
int main()
{
int playerNumber; string name; cout << Enter your player number << endl; cin >> playerNumber; cout << Enter your first and last name << endl; getline(cin, name);
cout << Hello << name << You are # << playerNumber << endl;
return 0;
}
a) Enter you first and last name
Hello Sidney Crosby You are #87
b) Enter you first and last name
Hello Sidney You are #87
c) Nothing, you need to use cin to read the name!
d) Enter you first and last name
Hello You are #87
4) Select the code which correctly implements the following logic: Read in hours worked, if hours less than or equal to forty, calculate pay as hours times rate, otherwise pay is time and one half for hours over forty
a) cout << Enter Hours worked << endl; cin >> hours; if(hours = 40) pay = hours * rate; else pay = 40 * rate + (hours 40) * rate * 1.5;
b) cout << Enter Hours worked << endl; cin >> hours; if(hours <= 40) pay = hours * rate; else pay = 40 * rate + (hours 40) * rate * 1.5;
c) cout << Enter Hours worked << endl; cin >> hours; if(hours <= 40) pay = hours * rate; else pay = hours * rate * 1.5;
d) cout << Enter Hours worked << endl; cin >> hours; pay = 40 * rate + (hours 40) * rate * 1.5;
5) What will be displayed by this program fragment? (Be careful!) int num1=0, num2=0; num1 = 14; if (num1 = 10) num2 = 2 * num1; cout << num1 << << num2 << endl;
a) 14 0
b) 0 0
c) Nothing! Syntax error.
d) 10 20
6) What will the following program display if the user enters 9: #include
a) 28
b) 9
c) 12
d) 18
7) Which program fragment gets input from the keyboard and then calculates the total outside surface of a rectangular box.
a)
cout << Enter length width and height of a box << endl; cin >> length >> width >> height; surface = 2*(length * width + width * height + length * height); |
b)
cout << Enter length width and height of a box << endl; cin >> length >> width >> height; surface = calculateSurface(length, width, height); |
c)
cout << Enter length width and height of a box << endl; cin >> length >> width >> height; surface =length * width * height; |
d)
cout << Enter length width and height of a box << endl; cin >> length >> width >> height; surface = 2*3.14159 * (length * width * height); |
8) Select the correct switch statement which will display Apple, Banana, or Orange depending on whether the char variable fruit contains A, B or O. If it does not contain one of those letters, display Unknown.
a)
switch(A, B, C) { case A: cout << Apple << endl; break; case B: cout << Banana << endl; break; case O: cout << Orange << endl; break; default: cout << "Unknown" << endl; } |
b)
switch(fruit) { case 1: if(fruit == 'A') cout << Apple << endl; break; case 2: if(fruit == 'B') cout << Banana << endl; break; case 3: if(fruit == 'O') cout << Orange << endl; break; default: cout << "Unknown" << endl; } |
c)
switch(fruit) { case A: cout << Apple << endl; break; case B: cout << Banana << endl; break; case O: cout << Orange << endl; break; default: cout << "Unknown" << endl; } |
d)
switch(fruit) { case "A": cout << Apple << endl; break; case "B": cout << Banana << endl; break; case "O": cout << Orange << endl; break; default: cout << "Unknown" << endl; } |
a) if( country !=Canada || country !=Mexico )9) Which if statement below will implement the logic, all countries except Canada and Mexico are charged a 10% import duty?
{ total*=1.10; }
b) if( country !=Canada && country !=Mexico ) { total*=1.10; }
c) if( country ==Canada && country ==Mexico ) { total*=1.10; }
d)
if( country ==Canada || country ==Mexico ) { total*=1.10; } |
10)
What is the value of setting after this assignment statement?
int setting; setting = (29 / 865) * 96877 * 8752235;
a) 28,426,400
b) Overflow, number too large for an int
c) 847,890,000
d) 0
