- Here is the main function in a program int main () { int x = 30; //more code goes here someFunction (x) ; cout « x; return 0; } Assume the heading for someFunction is written correctly with an integer parameter named x, and that this is the body of that function: { x = x * 20; //more code goes here } What will be the output? Just enter a number. If there would be an error, enter -999arrow_forwardExercise 6: Write a program that reads from the user three pieces of information: The current population of a country, the annual birth rate of the country, and its annual death rate. The program should then calculate the expected population for the following year and display the results as shown in Figure 6. Please note that population for the following year is calculated as sum of the current population, and the number of births by the end of the year minus the number of deaths by the end of the same year. Name your program Lab3_Id_ex6.py, where Id is your university Id. Include the design of your solution as comments at the beginning of your program. Test your solution with different input data. Please enter the current population of the country: 1800000 Please enter the birth rate: 0.017 Please enter the death rate: 0.005 Current Population Number of Number of Deaths Next Year Births Population 1800000 30600 9000 1821600 Figure 6: Sample Runarrow_forwardpython solution please Task 1Description let's consider a case when you need a lot of coffee. Maybe you're hosting a party with a lot of guests! In these circumstances, it's better to make preparations in advance.So, we will ask a user to enter the desired amount of coffee, in cups. Given this, you can adjust the program by calculating how much water, coffee, and milk are necessary to make the specified amount of coffee.Of course, all this coffee is not needed right now, so at this stage, the coffee machine doesn't actually make any coffee yet. ObjectivesLet's break the task into several steps:First, read the numbers of coffee drinks from the input.Figure out how much of each ingredient the machine will need. Note that one cup of coffee made on this coffee machine contains 200 ml of water, 50 ml of milk, and 15 g of coffee beans.Output the required ingredient amounts back to the user. ExamplesThe greater-than symbol followed by space (> ) represents the user input. Notice that…arrow_forward
- 6. Write a program which reads string and rewrite it in alphabetical order. For example, the word STRING should be written as GINRST. 7. Write a program to replace a particular word by another word in a given string. For example the “PYTHON” should be replaced by “C” in the text “It is good to program in PYTHON language”. 8. Write a program that will find the maximum number from 3 float type numbers. You have to usethe function getMax which will take 3 pointer variables and return the maximum number.arrow_forwardPlease review the image below. Produce the program in C++. Upload screenshots of Code and Output, as well as the source code. 7arrow_forward. Complex mathematical expressions can sometimes be simplified by breaking out partof the expression and putting it in a function.arrow_forward
- A particular talent competition has 5 judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer’s final score is determined by dropping the highest and lowest score received, then averaging the 3 remaining scores. Write a program that uses these rules to calculate and display a contestant’s score. It should include the following functions: • void getJudgeData() should ask the user for a judge’s score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the 5 judges. • double calcScore() should calculate and return the average of the 3 scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the 5 scores.Two additional functions, described below, should be called by calcScore, which uses the returned information to determine which of the scores to drop.•…arrow_forwardIf you run the following program, in which order the statements of this program will be executed? Your answer should be a sequence comma separated of line numbers without any extra spaces, e.g., 1,2,3,4,5,6,7,8 etc. What will this code print out?arrow_forwardNeed python help running code and others. Functions are ideal for use in menu-driven programs. When the user selects an item from a menu, the program can call the appropriate function. Write a menu-driven program for Burgers. Display the food menu to a user (Just show the 5 options' names and prices - No need to show the details!) Use numbers for the options and the number "6" to exit. If the user enters "6", your code should not ask any other questions, just show a message like "Thank you, hope to see you again!" Ask the user what he/she wants and how many of them. (Check the user inputs) Keep asking the user until he/she chooses the exit option. Use a data structure to save the quantities of the orders. You should use ArrayLists/Array Bags, or LinkedLists/LinkedBags (one or more of them) to save data. Calculate the price. Ask the user whether he/she is a student or a staff. There is no tax for students and a 9% tax for staff. Add the tax price to the total price.…arrow_forward
- 10) Write a program that translates a letter grade into a number grade. Letter grades are A, B, C, D, and F, possibly followed by + or -. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F-. The symbol + increases the numeric value by 0.3, and the symbol - decreases it by 0.3. For example: Enter a letter grade: B- The numeric value of B- is 2.7.arrow_forwardPROBLEM: Write a program that computes the equivalent resistance of a purely series and purely parallel electric circuit. SPECIFICATIONS: • The program will ask the user to choose whether to compute for the equivalent resistance of a series or parallel combination. • The user will input three resistance values R1, R2, and R3 in ohms. • The program will provide an output of equivalent resistance in series (Rs) or parallel (Rp). • You may only use the codes that we studied in our lectures. • All lines of codes should have a comment. To recall, the formula for solving the resistance for a purely series and purely parallel circuit are: a. Series Circuit: R1 120 ohms R2 Vs 100 V Rs = R7 = R1 + R2 + R3 + …+ Rn ... 30 ohms R3 50 ohms b. Parallel Circuit: 1 1 1 + R1' R2 ' R3 1 1 1 ...

You are required to develop a Java Program to assist the customer service department to provide good quality of services to the customer. Fix deposit is one of the most commonly asked services. Therefore, you are asked to develop a calculator for fix deposit to be included in the ATM display. The available options for ATM display is Fix Deposit and Cancel. When different option is chosen, different inputs from a user are required. Figure 6 shows the expected outputs on the ATM display. When the option Cancel is chosen, the user will exit from the system. Fix Deposit: Annual interest (%) : 3.0 Principal of saving (RM):Z Number of years of saving (n): Total savings (RM): figure 6 Based on Figure 6, the annual interest given by the bank is 3% and will be displayed on ATM screen.
