Program Plan Intro

Two-dimensional array:

A two dimensional array is also called as multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array.

This is useful for storing same type of multiple sets of data in the same place.

The main advantage is that one-dimensional array can hold only one type of value where as two dimensional array can hold multiple sets of data in the form of rows and columns.

The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns.

Example:

//Declaring multi-dimensional array

double testmarks[5][5];

The above statement is used to create a multidimensional array with “5” rows and “5” columns; the first square bracket is used to refer the number of rows and the second square bracket is used to refer the number of columns.

Algorithm to define the two dimensional array:

Start the program

Declare the constant size for the rows as “30” and columns as “10” using “const” keyword

Then, define the two-dimensional array name as “grades[][]” with the integer data type and pass the row value and column value using the variable name

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…
