Complete each statment:

$37.$ The $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ operator compares two Boolean values and returns TRUE

if and only if one, and only one, of the expressions is true.

$38.$ The REPEAT loop is considered as a$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ loop because it executes the statements in the loop body at least once and then checks the condition.

$39.$ A $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$literal is simply any string value surrounded by quotes.

$40.$ The $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$keyword executes a stored program.

$41.$ The$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ loop executes while the condition is FALSE.

$42.$ The$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$function removes only leading whitespace from a string.

$43.$ An $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$can be created to define the way in which the stored program

should respond to one or more error conditions.

$44.$ The WHILE loop is considered as a $\_\_\_\_\_\_\_\_\_\_\_\_\_$ loop because it checks the condition

before executing the statements in the loop body.

$45.$ You assign a new value to a variable after it has been declared by using a $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ statement.

$46.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$are similar to stored procedures, but their execution results in the return of a single value

$47.$ A $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$is a named data item whose value can change during program execution.

$48.\_\_\_\_\_\_\_\_\_\_\_\_\_\_$statements alter the flow of control in the program by allowing

code to be executed based on the value of some expression.

$49.$ A $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$can be placed both before the BEGIN statement and after the END statement to name the block.

$50.$ The$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ mode determines how stored programs deal with attempts to assign invalid values to variables.
