compute the average of the grades. Output
the average of the three exams. Together with
the average, also include a Remark: Passed in
the output if the average is greater than or
equal to 70, otherwise output Remark: Failed.
NOTE:
Your source code must display any of the given sample output below.
It means your source code should be flexible enough to meet any of the given
sample output.
Your source code output must be identical to any of the given sample output.
It means you have to strictly follow what are the displayed text, labels, casing of
characters in the sample output.

Write a program that reads from the user a character (‘s’ or ‘a’).
∙ If the character is ‘s’, the program reads 4 numbers from keyboard and then finds their sum. ∙ If the character is ‘a’, the program reads 4 numbers from keyboard and then finds their average. ∙ Otherwise, it prints “Wrong character”
Sample Run:
Sample Run1:
Enter a character (s or a): s
Input 4 numbers:
10.5
12
31

- Write a program that receives a double value from the user, deducts 1 from it, and prints it with 3-digit precision. The program should continue until the user enters a negative number (e.g. -2) as input. Sample Input: 12.34567 11.587 14.57 -19.5 Sample Output: 11.346 10.587 13.570arrow_forwardYou are making a program for a bus service. A bus can transport 50 passengers at once. Given the number of passengers waiting in the bus station as input, you need to calculate and output how many empty seats the last bus will have. Sample Input: 126 Sample Output: 24 Explanation: The first bus will transport 50 passengers, leaving 126-50=76 in the station. The next one will leave 26 in the station, thus, the last bus will take all of the 26 passengers, having 50-26=24 seats left empty. Hint: The modulo operator % can help to determine the number of passengers for the last bus.arrow_forwardYou are to create a program consisting of only the following lines of code. You may put these lines of code in any order, and can re-use the lines as frequently as you wish to. There will be more than one way to achieve the result – try to see if you can obtain the output using fewer lines of code.x = 1y = 10z = 0x = yx += 1y += xy *= xz += xz += yprint(z)The last line of your program print(z) should print out each of the following results, when run:131128123100000000000000000000000000000000 [Note: that’s 1032]4321arrow_forward
- Write a program that accepts a number corresponding to a plane figure: Right Triangle Rectangle Circle The program will then ask for the following: base and height – if the previous input is 1 (right triangle) width and length – if the previous input is 2 (rectangle) radius – if the previous input is 3 (circle)SPECIFICATIONS: - The program will then display the perimeter (circumference of the circle) and area of the chosen figure. You’re free to format the input/output display. The numeric output should be computed and NOT HARD-CODED. - The program will display “invalid input” if the initial input is not 1,2 or 3. After this, the program will terminate.- The next input (dimension/s of the chosen figure) will be stored on a float data type. The program will automatically terminate if the input is not a number.- Observe proper code indention - All lines should have a comment- Save your cpp file as Surname - PE (Example: Pangaliman - PE.cpp)TEST CASES: If the user inputs…arrow_forwardWrite a program that reads from the user a character ('s' or 'a'). If the character is 's', the program reads 4 numbers from keyboard and then finds their sum. If the character is 'a the program reads 4 numbers from keyboard and then finds their average. Ötherwise, it prints "Wrong character Sample Run: Sample Runl: Enter a character (s or a) : s Input 4 numbers: 10.5 12 31 44 The sum of these 4 numbers is: 97.5 Sample Run2: Enter a character (s or a): a Input 4 numbers: 10 12 31 44 The average of these 4 numbers is: 24.375 Sample Run3: Enter a character (s or a): d Wrong characterarrow_forwardWrite a program that reads a person’s name in the following format: first name, then middle name or initial, and then last name. The program then outputs the name in the following format:last name, first name. middle initial.For example the inputMary Average User should produce the outputUser, Mary A.Your program should work the same and place a full stop after the middle initial even if the input did not contain a full stop. Your program should allow for users who give no middle name or initial. In that case, the output of courses contains no middle name or initial. For example, the inputMary User should produce the outputUser, MaryYour program should also accept names in lowercase, uppercase or a mix of lowercase and uppercase, and display that in the correct format, e.g. if the input ismArY average USERshould produce the outputUser, Mary A.Use C-strings and assume that each name is at most 20 characters long.Hint: it may be easier to use 3 C-strings.arrow_forward
- A variable like user_num can store a value like an integer. Extend the given program as indicated. Output the user's input. Output the input squared and cubed. Hint: Compute squared as user_num * user_num. Get a second user input into user_num2, and output the sum and product. Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs. Enter integer: 4 You entered: 4 4 squared is 16 And 4 cubed is 64 !! Enter another integer: 5 4 + 5 is 9 4 * 5 is 20arrow_forward(This if for mindtap on cengage, if not possible, use devc++ 5.11 but mindtap is more accurate, mindtap is very tricky with wording so please make sure everything is word for word on the sample picture) Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate. The program should then output each candidate’s name (Candidate), the number of votes received (Votes Received), and the percentage of the total votes received by the candidate (% of Total Votes). Your program should also output the winner of the election. Your program must contain at least the following functions: a function to determine the sum of votes. a function to output the winner of the election.arrow_forwardQ1: A, B, C are three positive numbers (A<=B<=C). Given a list of seven numbers which are made of A, B, C, A+B, B+C, A+C, and A+B+C. Please find A, B and C use given seven numbers. Sample input: 2 2 11 4 9 7 9 Sample output: 2 2 7 You could use additional test case to test your program: Input: 41 19 22 38 22 19 3 Output: 3 19 19 Input: 148385247 819365820 793320372 26045448 122339799 670980573 697026021 Output: 26045448 122339799 670980573 Input: 326552445 762589144 699462434 63126710 436036699 372909989 389679155 Output: 63126710 326552445 372909989arrow_forward
- Write a program that implements a tip calculator. Your program should ask the user for the bill amount and the percentage of the tip, and then output the dollar amount of the tip and the final bill in three different formats. (see sample below) Example: Enter the bill amount: 27.95 Enter tip percentage: 17 A 17.0% tip on $27.95 equals $4.7515. The total bill is: 32.701499999999996 The total bill is $32.7. The total bill is $32.70.arrow_forwardWrite a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is 93, the output is: 93 92 91 90 89 88 Ex: If the input is 77, the output is: 77 Ex: If the input is not between 20 and 98 (inclusive), the output is: Input must be 20-98 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits; do not write a large if-else for all possible same-digit numbers (11, 22, 33, ..., 88), as that approach would be cumbersome for large ranges.arrow_forwardWrite a R program that takes an input from the user and prints if the number is: 1.Divisible by 5 and 6 or, 2.Only divisible by 5 or, 3.Only divisible by 6 Example 1: Input: 5 Output: 5 is only divisible by 5. Example 2: Input: 30 Output: 30 is divisible by 5 and 6.arrow_forward
