Which directive is used when defining 64-bit IEEE long reals?
Taya2010 [7]

Answer:

The answer is "Option b".

Explanation:

In the project of IEEE-754 to define 64 -bit we require a REAL8 double precision that is equal to 8 bytes and 64 bit, and it is also used for floating-point arithmetic, and other options were not correct that can be described as follows:

  • In option a, REAL4 is used to define 32-bit, that's why it is not correct.
  • In option c, This type of declaration is not valid in IEEE, that's why it is wrong.
  • In option d, The REAL is a keyword that is used to define a value but in this, there is no value to define, that's why it is wrong.

for (int iLoop=0; iLoop<n; iLoop++)

{

       if (userString[iLoop]==userChar)

       {

        countReturn++;

 }

}

return(countReturn);

}

 

/******************************************

     to the string that is stripped of the whitespace chars;

   

  Returns NULL pointer is empty string is passed;  

     Side Effects:

What two devices in a computer should be considered "black boxes," and should never be opened due to risks involving charged cap
NNADVOKAT [17]

The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.

Explanation:

  • Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
  • To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
  • A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.
