I need help problem: A two dimensional random walk simulates the behavior of a particle moving in a grid of points. At each step, the random walker moves north, South, east, or West with probability 1/4, independent of previous moves. Compose a program that takes a command line argument n and estimates how long it will take a random walker to hit the boundary of a 2n-by-2n square centered at the starting point.
Solve the problems Solve the quadratic equation 2x^2 + 6x + 4 = 0. Implement a function that takes incoefficients A,B,and C forthequadratic equation Ax2 + Bx + C = 0 and computes the two solutions. Have the function return the number of valid (not NaN) solutions and fill in the return arguments so the smaller of the two solutions is first.
(Electrical eng.) You’ve been asked to write a C++ program to calculate the total resistance of a series circuit. In this circuit, the total resistance is the sum of all individual resistance values. The circuit consists of a number of 56-ohm, 33-ohm, and 15-ohm resistors. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. The number of 56-ohm resistors is m, the number of 33-ohm resistors is n, and the number of 15-ohm resistors is p. d. Test the formula written for Exercise 1c using the following sample data: m=17,n=24,andp=12.

Construct C++ program to solve a given problem using appropriate programming techniques. Write a program that will calculate and print bills for the city power company. The rates vary depending on whether the use us residential, commercial, or industrial. A code of R means residential use, a code of C means commercial use, and a code of I means industrial use. Any other code should be treated as an error. The rates are computed as follows: R: $6.00 plus $0.052 per kwh used. C: $60.00 for the first 1000 kwh and $0.045 for each additional kwh. I: Rate varies depending on time of usage Peak hours: $76.00 for first 1000kwh and %0.065 for each additional kwh. Off-peak hours: $40.00 for first 1000 kwh and $0.028 for each additional kwh. Your program should prompt the user to enter an integer account number, the use code (type char), and the necessary consumption figures in whole numbers of kilowatt-hours. Your program should display the amount due from the user.
