- Compute the weakest precondition for the sequence of statements: (Statement 1) b = 2b + 1; (Statement 2) b = b-3{b < 0}In a Java if-statement, a _________ goes in the blank in the following: If(_________)Write the following statements in terms of ?, ?, ?, and logical connectives:a. Either 4 > 1 or 4 < 5.b. If 3 ≤ 3 , then 2 > 2. c. It is not the case that 2 > 2 or 4 > 1
- in java If b is 7 and c is 10, the value of c after the following statement is executed is _____. c *= b--;I don't understand why if (isSolution==true) or if (isSolution = true) cannot be a legal start of a if statement as the isSolution was declared and assigned false. Logically, it makes sense, but I don't understand how to work out the syntax. Java Code: import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */Scanner scnr= new Scanner(System.in);int x1=scnr.nextInt();int y1=scnr.nextInt();int z1=scnr.nextInt();int x2=scnr.nextInt();int y2=scnr.nextInt();int z2=scnr.nextInt();int x=0;int y=0;Boolean isSolution=false; for (int i= -10; i < 11; i++) {for (int j= -10; i < 11; j++) {if ((x1 * i + y1 * j == z1) && (x2 * i + y2 * j == z2)) isSolution = true; x=i;y=j; break;}}} if (isSolution==true) {System.out.println("x= " +x+ "y= " +y); } else {System.out.println("There is no solution");}}An electricity board charges the following rates to domestic users:-Units consumed TariffFor the first 100 units Rs. 5 per unitFor the next 200 units Rs.10 per unitFor the next 300 units Rs.15 per unitWrite a C++ program using class to read the names of users and number of units consumed andprint out the charges (in Rs.) with names.

- Hi, I am looking for assistance for a code for Java programming Write multiple if statements: If carYear is before 1967, print "Probably has few safety features." (without quotes). If after 1969, print "Probably has head rests.". If after 1992, print "Probably has electronic stability control.". If after 2000, print "Probably has airbags.". End each phrase with period and newline. Ex: carYear = 1995 prints: Probably has head rests. Probably has electronic stability control.Write a program in java that determines the value, true or false, of the following logical expressions, assuming that the value of the (type int) variables cont is 10 and limite is 20 (cont == 0 ) && (limite < 20) (limite >= 20) || (cont < 5) ((limite/(cont-10)) > 7) || (limite <20) (limite <= 20) || ((limite/(cont-10)) > 7) ((limite/(cont-10)) > 7) && (limite < 0) (limite < 0) && ((limite/(cont-10))> 7)Can I please have the answer in C++ language 4.7: Time Machine Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time. A time is specified in your program with three variables: int hours, minutes; bool isAM; // You can also use a char, i.e. A or P for example, to represent 11:50 PM, you would store: hours = 11,minutes = 50, isAM = false or if using a char, hours = 11,minutes = 50, isAM = 'A' This means that you need six variables to store a start and future time. Write a program that allows the user to enter a start time and a future time. Include a function named computeDifference that takes the six variables as…
- State the order of evaluation of the operators in each of the following Java statements, and show the value of x after each statement is performed: a) int x =7+3 *6/2-1; b) int x =2% 2+2*2-2/2;In java write a program that takes four int command-line arguments w, x, y, z,. define a boolean variable whose value is true if the four values are either in strictly acending order (w<x<y<z) or strictly descending order (w>x>y>z), and false otherwise, then display the boolean variable value. Note: Do not use if statements on the program Note: Assume that the inputs will always be integersWrite the following compound statement in terms of the simple statements p, q, and r.
