- b. b = (c + 10) / 3 {b > 6)
- c. a = a + 2 * b - 1{a > 1}

Compute the weakest precondition for each of the following sequencesof assignment statements and their postconditions:1. a = 2 * b + 1;b = a - 3{b < 0}2. a = 3 * (2 * b + a);b = 2 * a - 1{b > 5}
In C++
1. Declare, define, and test the following function to check for order by name:bool isSortedByName(const Student * sa, int size);2. Declare, define, and test the following function to check for order by ID:bool isSortedById(const Student * sa, int size);3. To print out a Boolean value as true or false, rather than 1 or 0, precede each with boolalpha:cout << "True is " << boolalpha << true << ", False is " << boolalpha << false <<endl;
Write the reccurence relation for the following function (in C-style code)
void T(n){
if(n>1){
int j;
for(j = n; j>1; j = j/2);
T(n/2); T(n/2);
}

Malik In C++ In this programming exercise, you use abstract classes and pure virtual functions to design classes to manipulate various types of accounts. For simplicity, assume that the bank offers three types of accounts: savings, checking, and certificate of deposit, as described next. Savings accounts: Suppose that the bank offers two types of savings accounts: one that has no minimum balance and a lower interest rate and another that requires a minimum balance and has a higher interest rate. Checking accounts: Suppose that the bank offers three types of checking accounts: one with a monthly service charge, limited check writing, no minimum balance, and no interest; another with no monthly service charge, a minimum balance requirement, unlimited check writing, and lower interest; and a third with no monthly service charge, a higher minimum requirement, a higher interest rate, and unlimited check…arrow_forwardRedo Programming Exercise 1 by overloading the operators as nonmembers of the classrectangleType.

OUTPUT SHOULD BE LIKE IN THE TABLE.arrow_forwardC PROGRAM Reverse + Random Formula In the code editor, there's already an initial code that contains the function declaration of the function, computeReverseNumber(int n) and an empty main() function. For this problem, you are task to implement the computeReverseNumber function. This function will take in an integer n as its parameter. This will get the reverse of the passed integer and will then compute and return the value: result = (original_number + reverse_of_the_number) / 3 In the main() function, ask the user to input the value of n, call the function computeReverseNumber and pass the inputted value of n, and print the result in the main() with two (2) decimal places.

If reaching one's objective can be done without making use of local declarations, then doing so is a waste of time. Why bother using value parameters when you can just use references as your arguments in any function? How crucial are value parameters when it comes to the processing of programmed data?arrow_forward
