- (Data processing) Years that are evenly divisible by 400 or are evenly divisible by 4 but not by 100 are leap years. For example, because 1600 is evenly divisible by 400, 1600 was a leap year. Similarly, because 1988 is evenly divisible by 4 but not by 100, it was also a leap year. Using this information, write a C++ program that accepts the year as user input, determines whether the year is a leap year, and displays a message telling the user whether the entered year is or is not a leap year.(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.Numerical analysis) Given a number, n, and an approximation for its square root, a closer approximation of the actual square root can be found by using this formula: newapproximation=(n/previousapproximation)+previousapproximation2 Using this information, write a C++ program that prompts the user for a number and an initial guess at its square root. Using this input data, your program should calculate an approximation of the square root that’s accurate to 0.00001. (Hint: Stop the loop when the difference between the two approximations is less than 0.00001.)
- Q.3 Write a C++ program that calculates the volume of a solid cone. The formula is: volume = ((0 radius20 height)/3 Input the values of height and radius.C++ Programming Exercise: A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.Q10/ Write a program in c++ that converts Celsius to Fahrenheit according to the following equation: F = 9/5 C+32 .By using functions
- PLEASE SOLVE THIS IN C++ CODE ONLY! PLEASE READ AND DO THE PROGRAM WITH ACCORDING TO THE CONDITIONS GIVEN. PLEASE ALSO WRITE THE USE OR FUNCTIONS OF EACH CODE USED BY INSERTING ITS USE EVERY LINE USING "//" A palindrome is a string that reads the same from front to back as it does from back to front, e.g., "racecar", "radar", "21012". Write a program that will identify whether a given line of input is a palindrome or not. Your program must also be able to determine the following sample inputs as palindromes, aside from identifying one-word inputs: Able was I 'ere I saw Elba. Madam, I'm Adam. A man, a plan, a canal, Panama. These samples require that your program must ignore spaces and punctuations, and consider uppercase and lowercase letters to be the same. Include necessary functions in your program to process the input. You can also use existing functions from the string library.Need help with a C++ program Write a C++ program that helps a person determine how long they can hike for under various conditions on a given supply of water.

- (Guess the Number) Write a C program that plays the game of “guess the number” as follows: Your program chooses the number to be guessed by selecting an integer at random in the range1 to 1000. The program then types:I have a number between 1 and 1000.Can you guess my number?Please type your first guess.a. Write a c program that asks a user for an integer. Declare a variable num3. Let num3 = --x; Display the values of x, and num3.b. Write a c program that asks a user for an integer. Declare a variable num4. Let num4 = x--; Display the values of x, and num4.. In the sport of diving, seven judges award a score between 0 and 10, where each score may be a floating-point value. The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points. The total is then multiplied by 0.6 to determine the diver’s score. Write a c++ computer program that inputs a degree of difficulty and seven judges’ scores, and outputs the overall score for that dive. The program should ensure that all inputs are within the allowable data ranges.
