Write a program that compares the values of y1 and y2 in the following expressions for values of n up to 100 in increments of 10. Does the result surprise you?PROBLEM:Write a program that prompts the user to input any digit then swap the position of the first and the last digit. Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices: 1. Sum of their square 2. Product of their square root 3. Square of their product The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping. Note: 1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit. 2. If the user chooses arithmetic operation No.2, format the output to three decimal places

- (Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.Airline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right. Geri bildirim gönder
- PROBLEM: 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 ... Rp RT Rn R1 R2 10 ohms Vs 40 ohms 40 Volts TEST CASES: If the user inputs a character: Computing for the equivalent resistance A. Series Combination B. Parallel Combination Enter Choice: B Enter R1: 1 Enter R2: 2…] In a triangle, the sum of the lengths of any two sides is greater than the lengthof the other third side. Write a program triangle.cc that prompts a user to enterthe lengths of three sides, checks if they form a triangle, and outputs if it is an isosceles,equilateral, scalene, or right triangle. Also, your program should output the perimeter andthe area of the triangle. In a right triangle, the square of the length of one side is equalto the sum of the squares of the lengths of the other two sides. An isosceles triangle hastwo sides of equal length. An equilateral triangle has all three sides with the same length.A scalene triangle has no equal sides. Your program should define and use the followingfunctions:(a) isTriangle - takes the 3 sides of a triangle and returns true if they form a triangle,false otherwise.(b) isIsosceles - takes the 3 sides of a triangle and returns true if they form anisosceles triangle, false otherwise.(c) isEquilateral - takes the 3 sides of a triangle and…Suppose you want to deposit a certain amount of money into a savings account with a fixed annual interest rate.
