Assigns the string "a" to the variable "b". Note that "b" must be declared and must be declared to be a string before it can be assigned. |
|
|
What is wrong with this code? var name; |
var is used to declare a variable and allows the program to select the variable type that makes the most sense. However, because this line doesn't assign anything to the variable on the same line, it doesn't know what type to declare it as. A fix like this would correct it and declare it as an int variable: var name = 3; |

Is this allowed? int a = 'a'; |
Yes. Using single quotes defines 'a' as a char character type. In binary, all characters are assigned a number. For 'a', it is 97. The integer, a, will be 97. |
|
|
What does this code do? Console.Write("\t1"); |
The "\t" inserts a tab. This will display a 1, tabbed over to the right. |
|
|
What does this code do? char a = (char)97; |
Converts 97 to a character. In this example, "a" would be the character 'a' because 97 is the number assigned to "a" on an ASCII/Unicode table. |
