What does the following variable declaration in C mean, assuming it occurs within a function called my_function() ?

static int x = 0 ;

x retains its value between calls to my_function()

x is a constant and cannot be changed within that function

x is a global variable and can be accessed from other functions directly

Syntax error, this is not a valid C statement.

What does the following variable declaration in C mean, assuming it occurs within a function called my_function() ?

static int x = 0 ;

x retains its value between calls to my_function()-(ANSWER)

x is a constant and cannot be changed within that function

x is a global variable and can be accessed from other functions directly

Syntax error, this is not a valid C statement.

Option 1 is correct answer because x retains its value between calls to my_function().

Option 2 is the not the correct answer because x can be changed within a function.

Option 3 is not the correct answer because variables declared within a function as static variables have local scope and belong only to that block or function.

Option 4 is not the correct answer because it is not a syntax error and is a valid C statement.

Consider the C program (twoupdate) to demonstrate race condition. In this assignment, we will implement Peterson's algorithm to ensure mutual exclusion in the respective critical sections of the two processes, and thereby eliminate the race condition. In order to implement Peterson's Algorithm, the two processes should share a boolean array calledflagwith two components and an integer variable called turn, all initialized suitably. We will create and access these shared variables using UNIX system calls relating to shared memory – shmget,...
