Program Plan Intro

a.

Assertion:

  • Asking questions in the programming language is help to test each statement in the program. It should be referred as an assertions or conditions.
  • If the assertion is true, then the answer to the question in a programming language is true.
  • If the assertion is false, then the answer to the question in a programming language is false.

Explanation of Solution

b.

Given statement:

“One” greater than “two”, but less than “three”

Assertion for the above statement is as follows:

(one > two) AND (one < three)

  • In the above Boolean expression, two expressions are combined using the “AND” operator.
  • First “one > two” expression is evaluated. If the value of “one” variable is greater than “two”, then the assertion is true...

Explanation of Solution

c.

Given statement:

All the three variables “one”, “two”, and “three” greater than zero.

Assertion for the above statement is as follows:

(one > 0) AND (two > 0) AND (three > 0)

  • In the above Boolean expression, three expressions are combined using the “AND” operator.
  • First “one > 0” expression is evaluated. If the value of “one” variable is greater than “0”, then the assertion is true. Otherwise the assertion is false...

Explanation of Solution

d.

Given statement:

“One” less than “two” or “one” less than “three”

Assertion for the above statement is as follows:

(one < two) OR (one < three)

  • In the above Boolean expression, two expressions are combined using the “OR” operator.
  • First “one < two” expression is evaluated. If the value of “one” variable is less than “two”, then the assertion is true...

Explanation of Solution

e.

Given statement:

“Two” greater than “one” and “three” less than “two”

Assertion for the above statement is as follows:

(two > one) AND (three < two)

  • In the above Boolean expression, two expressions are combined using the “AND” operator.
  • First “two > one” expression is evaluated. If the value of “two” variable is greater than “one”, then the assertion is true...
