After executing the statement given in the questions, the value of x is 2.

You can execute the given code in the question in any programming lanaguages. This program has switch statement

We executed the given code in C++, after executing the given code the value of x is 2.

The code is given below, and each line of code is commented that tells what does it mean.

#include <iostream>/* preprocessor directive , it includes the required library in the program*/

int main() // main entry of a program

{

int x = 5; // integer variable x that stores 5 as a value in it

switch(x) /*switch statement is a selection statement that evaluate each statement against the expression, if case will match, then the case body will get execute, if found break, then the program will be terminated */

{ case 5: //case 5 means, if x is equal to 5.

       x = 2; //then assign 2 to x.

       break;// break the program

   case 6: // if x is 6

       x ;//then the value of x will be retained i.e. 5

       break; // then terminate the program

   default: // if the above expression or case don't match

       x *= 2;//then value of x will be 10 i.e. x=x*10.

       break;// terminate the program

}

std::cout << x;// this statement will print the value of x.

   return 0;

}// program closing body.

after executing the above program, the value of x is 2.
