Write a function in C++ to take input an integer parameter n and return whether the number is a power of 2 or not.  bool isPowerof2(int n) {  // Return true if n is power of 2 }

Write a function that displays all the numbers between two integers in n lines, that are divisible by 5 or 7 (not by both). So, the function should take as parameters the minimum and maximum of integer numbers and n. If no values are passed to them, this function should display the numbers between 1 and 100 in 10 lines. Write a test program to test your function.  just in C++

Write a C++ Program, using functions, that, given a number greater than zero (0), the user will choose to calculate one of the following values:   the fibonacci series up to that number, where any number in the sequence is the sum of the previous two numbers:  the sum of the numbers up to that number, given by the equation:  the inverse square series up to that number, given by the equation:  the Sum of alternating sign Squares up to that number, given by the equation the Sum of the factorial to the power of the number, given by the equation:  Each option should have its own function.  A function can call another function.  Validate your input.Hint:  Use loops and static local variables if you need them.

I am learning c++, and I am really confused about the bool command. Please explain to me how the bool command used and when should I use it! thanks.
