Program Plan Intro

Logical “&&” Operator:

Logical operator combines the results of one or more conditions.

  • The logical “&&” is used to evaluate two expressions in order to obtain a single relational result.
  • It returns the Boolean value “True” when both the operands are true, otherwise returns “False”.
  • The first operand is evaluated first and all the side effects are completed before evaluating the logical “and” expression.
  • The second operand is evaluated only if the first operand is “True”.

Syntax for “&&” operator:

The syntax for “&&” operator is given below:

expression1 && expression2

Logical “||” Operator:

Logical operator combines the results of one or more conditions.

  • The logical “||” is used to evaluate two expressions in order to obtain a single relational result.
  • It returns the Boolean value “True” when one of the operands is “True”. It returns “False” only if both the operands are “False”.
  • The first operand is evaluated and all the effects are completed before it continues to evaluate the logical “||” expression.
  • The second operand is evaluated only if the first operands return “False”.

Syntax for “||” operator:

The syntax for “||” operator is given below:

Expression1 || expression2

Logical “!” Operator:

Logical NOT operator one conditions.

  • The logical “!” is used to evaluate one expressions in order to obtain a single relational result.
  • It returns the Boolean value “True”. If the operand is “False”.
  • It returns the Boolean value “False”. If the operand is “True”.

Syntax for “!” operator:

The syntax for “!” operator is given below:

!Expression2

After playing our giving implementation, your task is to implement Dinning Philosophers with semaphore in C, by including and Your implementation will require creating five philosophers, each identified by a number 0.4. Each philosopher will run as a separate thread. Create threads using Pthreads as discussed in the Lecture slides on Chapter 4 and Practice Lab on Threads. Your solution needs to accomplish the following: Implement in C (15 points) 1. dp1.c - You are to provide your solution to this assignment as a single C program named 'dp1.c using semaphore. Explain in you code (as comments) that the dead lock will happen or not. If there is a possible deadlock, you can simply solve the deadlock by pick the fork in order like the first solution in our slides. Solve Deadlock by Footman (15 points) 1. Here is a new solution to overcome the deadlock. The Dining Philosophers decide to hire a footman whose task to allow only four philosophers to sit on the table. When entering and…
