Answer / anyone

//Revision for Ahmed Ihmeid answer:
//Operator % prototype: int % int

bool isPowerOf2(int num)
{
int x;

x = num % (int(ceil(sqrt(num)));

if( x == 0)
return true; //it is a power of 2
else
return false; //it is not
}

proof:
4 % 2 = 0
16 % 4 = 0
22 % 5 != 0

Answer / ahmed ihmeid

bool isPowerOf2(int num)
{
float x;

x = num % (sqrt(num));

if( x == 0)
return true; //it is a power of 2
else
return false; //it is not
}

proof:
4 % 2 = 0
16 % 4 = 0
22 % 4.7 != 0

Write the program with at least two functions to solve the following problem. The members of the board of a small university are considering voting for a pay increase for their 10 faculty members. They are considering a pay increase of 8%. Write a program that will prompt for and accept the current salary for each of the faculty members, then calculate and display their individual pay increases. At the end of the program, print the total faculty payroll before and after the pay increase, and the total pay increase involved.

The program will first compute the tax you owe based on your income. User is prompted to enter income. Program will compute the total amount of tax owed based on the following: Income Tax 0 - $45,000 = 0.15 x income $45,001 - $90,000 = 6750 + 0.20 x (income – 45000) $90,001 - $140,000 = 15750 + 0.26 x (income – 90000) $140,001 - $200,000 = 28750 + 0.29 x (income – 140000) Greater than $200,000 = 46150 + 0.33 x (income – 200000) Dollar amounts should be in dollars and cents (float point numbers with two decimals shown). Tax is displayed on the screen.
