Step by step
Solved in 2 steps
- 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}Compute the weakest precondition for each of the following assignment statements and selection constructs. Detailed steps are needed. a = 2 * (b - 1) - 1 {a > 0} a = 2 * b + 1 b = a - 3 {b < 0} if (a == b) b = 2 * a + 1 else b = 2 * a {b > 1}1. Create a Java program to solve the problem of confusing the comparison operator (==) with the assignment operator (=)
- Describe in Java and C# the concept of a definite assignment..In the context of function calls, please explain the difference between reference semantics and value semantics, as well as the repercussions of this distinction. When is it OK to choose one option over the other? What are the advantages of both options?Give an example of a large-scale application and elaborate on whether or not explicit declaration is preferable to implicit declaration.
