On a piano, a key has a frequency, say fo. Each higher key (black or white) has a frequency of fo* r, where n is the distance (number of keys) from that key, and r is 2(1/12), Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value1:.2f} {your_value2:.2f} {your_value3:.2f} {your_value4:.2f} {your_value5:.2f}') Ex: If the input is: 440 (which is the A key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37 Note: Use one statement to computer = 2(1/12) using the pow function (remember to import the math module). Then use that r in subsequent statements that use the formula fn = f0 *r with n being 1, 2, 3, and finally 4.

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('%0.2f %0.2f %0.2f %0.2f %0.2f' % (your_value1, your_value2, your_value3, your_value4, your_value5))

Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements.
IN COARAL On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1.0/12.0). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output all frequencies with five digits after the decimal point, which can be achieved as follows:Put frequency to output with 5 decimal places Ex: If the input is: 440.0 (which is the A key near the middle of a piano keyboard), the output is: 440.00000 466.16376 493.88330 523.25113 554.36526 Note: Use one statement to compute r = 2(1.0/12.0) using the RaiseToPower() function. Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4.

Write a program that inputs a number and checks whether it is a perfect number or not. A perfect number is the number that is numerically equal to the sum of its divisors. For example, 6 is a perfect number because the divisors of 6 are 1, 2, 3 and 1+2+3=6
Write a program sequence.cc that prompts the user to enter the value of x, the pro- gram outputs the integer k such that ak = 1, the numbers a0, a1, a2, ..., ak, the largest number of the sequence a0, a1, a2, ..., ak, and the position of the largest number in the sequence.
Write a program that reads an integer and displays all its smallest factors in an increasing order. For example, if the input integer is 120, the output should be as follows: 2, 2, 2, 3, 5.
Write a program that takes as input the speed of a car e.g 80. If the speed is less than 70, it should print “Ok”. Otherwise, for every 5 km/s above the speed limit (70), it should give the driver one demerit point and print the total number of demerit points
Write a program by using c++ that inputs a number and checks whether it is a perfect number or not. A perfect number is the number that is numerically equal to the sum of its divisors. For example, 6 is a perfect number because the divisors of 6 are 1, 2, 3 and 1+2+3=6
Write a program that reads an integer age of kids, finds the maximum of them, and counts its occurances, finds the minimum of them, and counts its occurances. And Find the average ages. Assum that the input ends with number -1.
What is the output of the following code?Assume that int is 32 bits, short is 16 bits, and the representation is two’scomplement. unsigned int x = 0xDEADBEEF;unsigned short y = 0xFFFF;signed int z =-1;if (x > (signed short) y) printf("Hello");if (x > z) printf("World"); (a) Prints nothing.(b) Prints ”Hello”(c) Prints ”World”(d) Prints ”HelloWorld”
