- (Biology) The number of bacteria, B, in a culture that’s subject to refrigeration can be approximated by this formula: B=300000e0.032t e is Euler’s number 2.71828 (rounded to five decimal places). t is the time in hours the culture has been refrigerated. Using this formula, write, compile, and run a C++ program that prompts the user for a value of time, calculates the number of bacteria in the culture, and displays the result. For testing purposes, check your program by using a test input of 10 hours. After verifying your program, use it to determine the number of bacteria in the culture after 12, 18, 24, 36, 48, and 72 hours.(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.C program: The user should enter a number and then the next consecutive numbers are printed in. How would I approach this?
- State whether each of the following is true or false. If false, explain why c) The escape sequence \n when used in a printf format control string causes the cursor to position to the beginning of the next line on the screen.Please use C++ and Only Use Selection Statements PROBLEM:Consider the elevator in the Faculty of Engineering (5-storey). Write a program that accepts the floor number where a passenger (student/faculty/other personnel) will ride the elevator. The passenger can then input the target destination floor. SPECIFICATIONS:- Passengers can ride on any floor (1,2,3,4 or 5).- The program will prompt the user with the target destination floor. After the user input:- Program will display the floors which the elevator passes through, and finally the destination floor.- Elevator will not move if the input for the destination floor is the same as the present floor. The program will notify the user and then terminate.- Program will also terminate if the input destination is not 1,2,3,4 or 5- You’re free to format the input/output display.- Observe proper code indention- All lines should have a comment TEST CASES: If the starting floor is 1 and the destination floor is 5, The program will display: “…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…
- 8 -) Enter the C code for a 1-6 digit number that the user will enter from the keyboard,adds a number for each digit of this number, and if the result doubles, the total number is obtainedthe result and continues the program; if it is bot, it ends the program in the revelant place.State whether the following are true or false. If the answer is false, explain why.b) The break statement is required in the default case of a switch selection statement.C++ Programming Problem: To make telephone numbers easier to remember, some companies use letters to show their telephone number. For example, using letters, the telephone number 438-5626 can be shown as GET LOAN. In some cases, to make a telephone number meaningful, companies might use more than seven letters. For example, 255-5466 can be displayed as CALL HOME, which uses eight letters. Write a program that prompts the user to enter a telephone number expressed in letters and outputs the corresponding telephone number in digits. If the user enters more than seven letters, then process only the first seven letters. Also output the hyphen after the third digit. Allow the user to use both uppercase and lowercase letters as well as spaces between words. Moreover, your program should process as many telephone numbers as the user wants.
