Front

Given the following pseudocode, what will be displayed when the program is run?
int A = 10;
int B = 5;
Console.Write(A < B);
Console.Write(" ");
Console.Write(A >= B);
Console.Write(" ");
Console.Write(A != B);

Back

False True True

Front

Which of the following expressions (A, B, C) are considered logical expressions? A) 6 + 4 B) (6 + 4) >= 10 C) 4 < 10

Back

B and C only

Front

What is the difference between the following three if() statements?
double sodaCost = 2.50;
if (sodaCost > 2.00) Console.WriteLine("I'll have water instead");
if (sodaCost > 2.00)
Console.WriteLine("I'll have water instead");
if (sodaCost > 2.00)
Console.WriteLine("I'll have water instead");

break;
case 'B':
Console.WriteLine("80 - 89");
break;
case 'C':
Console.WriteLine("70-79");
break;
}

Back
