Write a C++ program to ask the user to input the electricity amount and calculate the total electricity bill by using the selection control structures according to the given condition: Round the numbers and keep only 2 decimal values, and use compound operators. From 0 to 50 electricity amount, multiply by 0.50 and display “The total electricity bill is =” From 51 to 60 electricity amount, multiply by 0.70 and display “The total electricity bill is =” From 61 to 70 electricity amount, multiply by 0.80 and display “The total electricity bill is =” Anything else display ” Invalid electricity data”

C++ variables can be assigned values without being declared.

Write a C++ program to ask the user to input the electricity amount and calculate the total electricity bill by using the selection control structures according to the given condition: Round the numbers and keep only 2 decimal values, and use compound operators. From 0 to 40 electricity amount, multiply by 0.20 and display “The total electricity bill is =” From 41 to 50 electricity amount, multiply by 0.30 and display “The total electricity bill is =” From 51 to 60 electricity amount, multiply by 0.40 and display “The total electricity bill is =” Anything else display ” Invalid electricity data

The logical AND operator (&&) returns true only if both operands are false.

 Syntax rules: rules that specify which statements (instructions) are legal or valid

Which one of these is not a parameterized stream manipulators that  require the iomanip header

 Logic errors are typically not caught by the compiler:

You can have multiple main() functions in a C++ program.

All variables must be initialized before they are used, but not necessarily during declaration

the Library is automatically included in every program without needing to include any headers.
