Operations

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…

Expert Solution & Answer

Chapter 3.10, Problem 3.10.1CP

Explanation of Solution

Given statements:

(true) && (3>4)

1^st part: The first part is given as “true”.

2^nd part: In the second part, the value “3” is not greater than “4”. Hence the second part is “false”.

The AND (&&) operation becomes “true” if both the parts are “true”. Otherwise, it is “false”.

Here, one part is “true” and the other part is “false”.

Therefore, (true) && (3>4) returns “false”

!(x>0) && (x>0)

Apply “1” in the place of “x”. Then the statement becomes “!(1>0) && (1>0)”

1^st part: In the first part, “1” is greater than “0”. But NOT operator makes this as “false”.

2^nd part: In the second part, the value “1” is greater than “0”. Hence the second part is “true”.

The AND (&&) operation becomes “true” if both the parts are “true”. Otherwise, it is “false”.

Here, one part is “false” and the other part is “true”.

Therefore, !(x>0) && (x>0)returns “false”

(x>0) || (x<0)

Apply “1” in the place of “x”. Then the statement becomes “(1>0) || (1<0)”

1^st part: In the first part, “1” is greater than “0”. Hence, it returns “true”.

2^nd part: In the second part, the value “1” is not less than “0”. Hence the second part is “false”.

The OR (||) operation becomes “true” if any one of the parts is “true”. Otherwise, it is “false”.

Here, one part is “true” and the other part is “false”.

Therefore, (x>0) || (x<0) returns “true”...
