(Conversion) a. Design, write, compile, and run a C++ program to convert temperature in degrees Fahrenheit to degrees Celsius. This is the equation for this conversion: Celsius=5.0/9.0(Fahrenheit32.0) Have your program convert and display the Celsius temperature corresponding to 98.6 degrees Fahrenheit. Your program should produce the following display (replacing the underlines with the correct values): For a Fahrenheit temperature of ___ degrees, the equivalent Celsius temperature is ___ degrees. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to convert 86.5 degrees Fahrenheit to its equivalent Celsius value.
(General math) a. The volume, V, of a cylinder is given by this formula: V=r2L r is the cylinder’s radius, and L is its length. Using this formula, write a C++ function named cylvol() that accepts a cylinder’s radius and length and returns its volume. b. Include the function written in Exercise 5a in a working program. Make sure your function is called from main() and returns a value to main() correctly. Have main() use a cout statement to display the returned value. Test the function by passing various data to it.
(General math) a. A balance has the following weights: 100 lb, 50 lb, 10 lb, 5 lb, and 1 lb. The number of 100 lb and 50 lb weights required to weigh an object weighing WEIGHT pounds can be calculated by using the following C++ statements: //Determinethenumberof100lbweightsw100=int( WEIGHT/100)//Determinethenumberof50lbweightsw50=int( ( WEIGHTw100100 )/50) Using these statements as a starting point, write a C++ program that calculates the number of each type of weight needed to weigh a 789 lb object. b. Without compiling or running your program, manually check the effect of each statement in the program and determine what’s stored in each variable as each statement is encountered. c. After verifying that your algorithm works correctly, compile and run your program. Verify that the results your program produces are correct. After verifying that your program is working correctly, use it to determine the weights required to weigh a 626 lb object.
(Hydraulics) a. Design, write, compile, and run a C++ program that calculates and displays the velocity of water flowing out of the tube shown in Figure 2.19. The velocity of water flowing into the tube is 1 ft/sec, the input tube radius is 0.75 in, and the output tube radius is 0.5 in. The output velocity is given by this formula: vout=vin( r in r out )2 v outistheoutputvelocity.v inistheinputvelocity.routistheradiusoftheoutputtube.r inistheradiusoftheinputtube. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the output velocity for a tube having an input radius of 1 in and an output radius of .75 in, when water is flowing into the tube at a rate of 1.5 ft/sec.
(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.
(Civil eng.) Write a C++ program to calculate and display the maximum bending moment, M, of a beam that’s supported on both ends (see Figure 3.8). The formula is M=XW(LX)/L, where X is the distance from the end of the beam that a weight, W, is placed, and L is the beam’s length. You program should produce this display: The maximum bending moment is xxxx.xxxx The xxxx.xxxx denotes placing the calculated value in a field wide enough for four places to the right and left of the decimal point. For your program, assign the values1.2,1.3,and11.2toX,W,andL.
(Electrical eng.) The amplification of electronic circuits is measured in units of decibels, which is calculated as the following: 10LOG(Po/Pi) Po is the power of the output signal, and Pi is the power of the input signal. Using this formula, write, compile, and run a C++ program to calculate and display the decibel amplification, in which the output power is 50 times the input power. Verify your program’s result by doing a hand calculation. After verifying that your program is working correctly, use it to determine the amplification of a circuit, where output power is 4.639 watts and input power is 1 watt.
(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.
Problem Statement: C++ PROGRAM A 4th grader is having trouble with Permutation and Combination problem in Mathematics, so a friend offered help to create a program they can use. The program contains 3 options, 1st option is for Permutation, 2nd option is Combination and 3rd is for terminating the system. For option 1, Permutation, they uses the following formula: nPr = ; where r must not be greater than n. It should not proceed if this condition is not met. For 2nd option, Combination, they uses the formula : nCr = ; where r must not be greater than n as well. For the 3rd option, the program owner’s information shall be displayed, like name, subject code and account number, before the program terminates. Requirements: Develop the required system and use cpp for the file name Remember that both n and r are variables, their values shall only be entered at run time. The program requires the use of any looping The program requires the use of any conditional Introduce…

Hi I need help please, I want to know how to make a code in C++ that will take 3 string user input, one string, one to search for and replace and then display it when I collect the user input in the main and call the function. Please help I am lost
PLease make this program work in C++ // This program has three functions: main, beep, and beeper #include <iostream>using namespace std;// Definition of function Beeper. This function displays a message. void Beeper(void) { cout << "I am now inside the function Beeper.\a\a\a\n"; } // Definition of function Beep. This function calls the function Beeper. void Beep(void) { cout << "I am now inside the function Beep.\a"; Beeper(); // Call function Beeper cout << "Now I am back in Beep.\a"; } void main(void) { cout << "I am starting in function main.\n"; Beep(); // Call function Beep cout << "Back in function main again.\n" }
