The EBNF description for a Java class definition header statement includes a start symbol <Java Class>, the <Class Name> non-terminal, and rules for <Identifier>.
The EBNF (Extended Backus-Naur Form) is a metasyntax notation used to describe the grammar of programming languages. For a Java class definition header statement, the EBNF rules would describe the syntax of the statement using non-terminal symbols and terminals.
The start symbol for the EBNF description of a Java class definition header statement would be a non-terminal symbol, which represents the header statement itself. This non-terminal symbol would then be expanded into other non-terminal symbols and terminals that describe the various components of the header statement, such as the class name, access modifiers, and the keyword "class".
The non-terminal for the user-defined name of the class would be defined using a separate EBNF rule, which would specify the valid naming conventions for Java classes, such as starting with an uppercase letter and using camel case for multi-word names.
Overall, the EBNF rules for a Java class definition header statement would provide a formal description of the syntax that a Java compiler would use to parse and interpret the statement. This can be useful for programmers who need to understand the grammar of the language in order to write correct and efficient code.

Which of the following is false?a) break and continue statements alter the flow of control.b) continue statements skip the remain in statements in the body of the loop in which they are embedded.c) break statements exit from the loop in which they are embedded.d) continue and break statements may be embedded within all C++ structures
Although the continue statement skips the remaining statements in the current iteration of the loop and moves on to the next one, the break statement ends the current loop or switch statement. Both are interchangeable in any C++ structure.
Loops and switch statements are used in C++ programming to continually run a sequence of instructions. The current loop or switch statement is stopped using the break statement, and control is then passed to the statement that comes after the terminated loop or switch. This is helpful if a certain condition is satisfied and you wish to leave the loop right away. The next iteration of the loop is started by the continue statement, which skips the remaining statements in the current iteration. When you wish to skip some statements during a loop iteration depending on a certain circumstance, this is helpful. Any C++ structure, including loops, switch statements, and nested structures, can employ both the break and continue commands.

write a conditional that multiplies the value associated with pay by one-and-a-half if worked_overtime is associated with true.
The code multiplies the value of the variable pay by 1.5 if worked_overtime is true.
Here's an example of a conditional statement in JavaScript that multiplies the value of pay by 1.5 if worked_overtime is true:
if (worked_overtime === true) {
pay = pay * 1.5;
}
Note that worked_overtime is assumed to be a boolean variable that is either true or false.
The given code uses a conditional statement to check whether the value of the variable worked_overtime is true. If the value is true, the code multiplies the value of the variable pay by 1.5 and assigns the result back to the same variable pay. This means that if the condition is true, the pay value will be updated to 1.5 times its original value, which represents a 50% increase in pay.
Note that the code assumes that the variables worked_overtime and pay are previously defined and have valid values assigned to them.
