Concept explainers

In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.

Basic Operators

An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.

Division Operator

We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:

Modulus Operator

Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo …

Operators

In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical…

Chapter 3.1, Problem 1STE

Determine the value, true or false, of each of the following Boolean expressions, assuming that the value of the variable count is 0 and the value of the variable limit is 10. Give your answer as one of the values true or false.

a. (count == 0) && (limit < 20)

b. count == 0 && limit < 20

c. (limit > 20) || (count < 5)

d. !(count==12)

e. (count == 1) && (x < y)

f. (count < 10) || (x < y)

g. !( ((count < 10) || (x < y)) && (count >= 0) )

h. ((limit/count) > 7) || (limit < 20)

i. (limit < 20) || ((limit/count) > 7)

j. ((limit/count) > 7) && (limit < 0)

k. (limit < 0) && ((limit/count) > 7)

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
