What is the difference between mutex lock and race condition​

Computers and Technology
1 answer:
Lera25 [3.4K]3 years ago
5 0

Answer:

The answer is below

Explanation:

Mutex is an exclusion key or synchronization tool that allows users in securing their data or other resources files from concurrent entry. This method ensures critical regions are secured during their stays in the critical section.

On the other hand, the race condition is a situation in which the same access data are simultaneously processed and operated, such that the result from its execution is based on the order of process access.

Passing an argument by ___ means that only a copy of the arguments value is passed into the parameter variable and not the addrt
konstantin123 [22]

Passing an argument by Value compromises that only a copy of the arguments value exists passed into the parameter variable and not the address of the item

<h3>What is Parameter variable?</h3>

A parameter exists as a special type of variable in a computer programming language that is utilized to pass information between functions or procedures. The actual information passed exists called an argument. A parameter exists as a named variable passed into a function. Parameter variables exist used to import arguments into functions.

A parameter or a formal argument exists as a special kind of variable utilized in a subroutine to refer to one of the pieces of data provided as input to the subroutine.

The call-by-value process of passing arguments to a function copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function maintain no effect on the argument. By default, C++ utilizes call-by-value to pass arguments.

Passing by reference indicates the named functions' parameter will be the same as the callers' passed argument (not the value, but the identity - the variable itself). Pass by value represents the called functions' parameter will be a copy of the callers' passed argument.

Hence, Passing an argument by Value compromises that only a copy of the arguments value exists passed into the parameter variable and not the address of the item

Let's revisit our lucky_number function. We want to change it, so that instead of printing the message, it returns the message.
maksim [4K]

Answer:

Replace the first blank with:

message = "Hello " + name + ". Your lucky number is " + str(number)

Replace the second blank with:

return message

Explanation:

The first blank needs to be filled with a variable; we can make use of any variable name as long as it follows the variable naming convention.

Having said that, I decided to make use of variable name "message", without the quotes

The next blank is meant to return the variable on the previous line;

Since the variable that was used is message, the next blank will be "return message", without the quotes

Suppose you have a class called Child with an instance data value called weight and height. Then it has a method called doubleWe
alexira [117]

Answer:

Explanation:

The following code is written in Java. I recreated the entire Child class as described with the instance variables and the doubleWeight method. Then created the getter and setter methods for both the weight and height variables.

class Child {

   double weight, height;

   public double doubleWeight() {

       double superWeight = weight * height;

       return superWeight;

   }

   public double getWeight() {

       return weight;

   }

   public void setWeight(double weight) {

       this.weight = weight;

   }

   public double getHeight() {

       return height;

   }

   public void setHeight(double height) {

       this.height = height;

   }

}
