Question 1: Other than in a FOR statement, when is the comma operator used?

Answer: The comma operator is commonly used to separate variable declarations, function arguments, and expressions, as well as the elements of a for statement.

Question 2: How can you tell whether a Loop ended prematurely?

Answer: Generally, loops are dependent on one or more variables. Your program can check those variables outside the loop to ensure that the loop executed properly.

Question 3: What is the difference between GOTO and longjmp( ) and setjmp()?

Answer: GOTO statement implements a local jump of program ex*****on and the longjmp() and setjmp() functions implement a nonlocal or far jump of program ex*****on. Generally, a jump in the ex*****on of any kind should be avoided because it is not considered a good programming practice to use such statements as GOTO and longjmp in your program.

Question 4: What is LVALUE?

Answer: The LVALUE is an expression to which a value can be assigned. The LVALUE expression is located on the left side of an assignment statement, whereas a RVALUE is located on the right side of an assignment statement. Each assignment statement must have a LVALUE and a RVALUE. The LVALUE expression must reference a storable variable in memory. It cannot be constant.

Question 5: Can an array be a LVALUE?

Answer: Is an ARRAY an expression to which we can assign a value? The answer to this question is, No! Because an array is composed of several separate array elements that cannot be treated as a whole for assignment purposes. The following statement is, therefore, illegal:
int x[5], y[5];
x = y;
You could, however, use a for loop to iterate through each element of the array and assign values individually

Technical Question 1:
What is a local block?

Answer:
A local block is any portion of a C program that is enclosed by the left brace ({) and the right brace (}).
An if statement or a switch statement can also contain braces, so the portion of code between these two braces would be considered a local block.

Technical Question 2:
Should variables be stored in local blocks?

Answer:
The use of local blocks for storing variables is unusual and therefore should be avoided, with only rare exceptions. One of these exceptions would be for debugging purposes, when you might want to declare a local instance of a global variable to test within your function. You also might want to use a local block when you want to make your program more readable in the current context.

Technical Question 3:
When is a SWITCH statement better than multiple IF statements?

Answer:
A SWITCH statement is generally best to use when you have more than two conditional expressions based on a single variable of numeric type.

Technical Question 4:
Is a default case necessary in a SWITCH statement?

Answer:
No, but it is not a bad idea to put Default statements in SWITCH statements for error or logic-checking purposes.

Technical Question 5:
Can the last case of a SWITCH statement skip including the Break?

Answer:
Even though the last case of a switch statement does not require a break statement at the end, you should add break statements to all cases of the switch statement, including the last case. You should do so primarily because your program has a strong chance of being maintained by someone other than you who might add cases but neglect to notice that the last case has no break statement.
