the set { hGi : G is CFG that does NOT generate all strings }, then N is r.e. (c) It is undecidable to determine whether an NFA accepts its own encoding. (d) If a language L is context-sensitive, then there is a Printer-TM that prints out L in order.

Answer:

a. false

b. false

c. false

d. true

Explanation:

(a) False, this is because the set of all real numbers are example of infinite uncountable set.

(b) False, this is because it is undecidable problem to test if a grammar G generates all possible strings over the alphabet and hence to check if set N containing all such CFG is not even recursive-enumerable.

(c) False, this is because there is decidable Turing machine to test if a NFA accepts the input string which includes it's own encoding.

(d) True, this is becsuse it's possible for context-sensative language.

In a switch statement, if a break statement is missing, _______________. Select one: a. the default case is automatically execut
Aleks [24]

Answer:

c. execution falls through the next branch until a break statement is reached

Explanation:

In a switch statement, if break is missing, then program continues to the next cases until it finds a break statement.

Consider the following example!

Example:

#include <iostream>

using namespace std;

int main()

{

  int choice = 1;

  switch (choice)

  {

      case 1:

      printf("This is case 1, No break\n");

      case 2:

      printf("This is case 2, No break\n");

      case 3:

      printf("This is case 3, with break\n");

      break;

      default: printf("Error! wrong choice\n");

  }

  return 0;

}

Output:

This is case 1, No break

This is case 2, No break

This is case 3, with break

We have 3 cases here and case 1 and 2 don't have break statements, only case 3 has a break statement.

We called the case 1, then program continued to case 2,  and finally to case 3 where it finds the break statement and terminates.

Therefore, we conclude that in a switch statement, if a break statement is missing, then execution falls through the next branch until a break statement is found.

During the troubleshooting of a pc that will not boot, it is suspected that the problem is with the ram modules. The ram modules
SOVA2 [1]

The RAM modules were not well placed or fitted firmly in the motherboard DIMM slots of the PC during toubleshooting.

What are RAM Modules?

RAM Modules have narrowly printed circuit boards that hold RAM chips (memory chips).

In order to function properly, RAM is expected to be placed or fitted firmly in the motherboard DIMM slots.

DIMM (Dual In-line Memory Module) is a module that contains one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard.
