In C++, using the assignment operator = in an if condition instead of the equality operator == causes a Symantec error.

The logical NOT operator (!) inverts the value of its operand. If the operand is true, the result is false, and vice versa.

 Logical (Boolean) operators are used to combine logical expressions

In C++, you can declare multiple variables of different types in a single statement.

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

The logical OR operator (||) returns false only if both operands are false.

 Logic errors are typically not caught by the compiler:

 A linker combines object program with other programs in the library to create executable code.

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

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 10 electricity amount, multiply by 0.40 and display “The total electricity bill is =” From 11 to 20 electricity amount, multiply by 0.50 and display “The total electricity bill is =” From 21 to 30 electricity amount, multiply by 0.60 and display “The total electricity bill is =” Anything else display ” Invalid electricity data”
