Which statement is false?
a. When we define a local variable in a block it can be referenced only in that block or in blocks in which that block is nested.
b. Labels are the only identifiers with function scope.
c. Labels can be used anywhere in the function in which they appear, but can not be referenced outside the function body.
d. Labels are used in switch statements and in goto statements..
"Labels are used in switch statements and in goto statements" is the false statement
d. Labels are used in switch statements and in goto statements..

Scope What is variable scope? What are the types of scope we can have in programming? What type of scope does a variable have when it is defined within a sub-block? What is a global variable? How are they typically declared? To modify a global variable inside of a function, what statement must we have at the beginning of the function’s body? Why is using global variables considered poor programming practice? What is a...

this is true and false for C++ (1 point each) Circle T for true or F for false for the following questions. 1. T/F The Boolean expression b1 || b2 evaluates to true if either Boolean value (b1, b2) is true. T/F The code we write in C++ (e.g. code in file project1.cpp) is referred to as source code. 2. 3. T/F The statement float scores[3][3] creates 3 arrays, each containing 3 floating-point variables. T/F For loops work best when...

3. Now let’s look at the Verilog implementation of the arbiter state machine. [Normally we would include an always block for the state update but we’re not going to bother with that here.] (a) Define the module interface and the state variables you will use. Also use a parameter statement so that you can use labels for your states. Remember to define the output signals as type reg, since you will be assigning to them inside the case statement, which...
Which statement is generally false? a. Statements preceding a for and statements in the body of a for should typically be merged into the for header. b. Limit the size of control statement headers to a single line, if possible. c. Initialization of a for loop control variable can occur before the for loop executes and not in the loop itself. d. The increment portion of a for header can be a decrement.
