ACER ASPIRE X3910 EVENT ID 41 KERNEL POWER CRITICAL


If it just stopped and restarted proper is nothing to worry cause it seam just like a memory dumping error or so ..If it asks to choose a boot on start ..just start normally or choose to start with the last known configuration that worked.
If it do not want to start it may be a case of corrupted boot file ..and need to repair the boot configuration using a operation system disk or the recovery partition ..My advice is to reinstall a clean copy if it makes troubles again ..It may have something in the system that cause it ..and reinstalling will remove the settings and programs ..and when you install them again try them one by one ..and you will know which one is not supported..

Can you convert dollar to peso in c++


1) Find the dollar to peso conversion rate. You can go to Reuters to get the latest exchange rate.

2) Then Argentinian peso for example:

int main()
{
double dollar, peso;
int rate;

peso = 0;
cout << "Enter dollar amount: ";
cin >> dollar;
cout << "Enter exchange rate:";
cin >> rate;
cout.setf(ios::fixed);
cout.precision(2);
peso += dollar * rate;
cout << dollar << " dallars is equal to " << peso << " peso's." << endl;

return 0;
}

With this program you input the amount in dollars and it will give you the amount in peso's.

Create program for A-D:


A.) If else statement using Javascript
<script type="text/javascript">
//If the time is less than 10, you will get a "Good morning" greeting.
//Otherwise you will get a "Good day" greeting.

var d = new Date();
var time = d.getHours();

if (time < 10)
{
document.write("Good morning!");
}
else
{
document.write("Good day!");
}
</script>

B.) Switch Case Statement Using C#
using System;

class SwitchSelect
{
public static void Main()
{
string myInput;
int myInt;

begin:

Console.Write("Please enter a number between 1 and 10: ");
myInput = Console.ReadLine();
myInt = Int32.Parse(myInput);

// switch with integer type
switch (myInt)
{
case 1:
Console.WriteLine("Your number is {0}.", myInt);
break;
case 2:
Console.WriteLine("Your number is {0}.", myInt);
break;
case 3:
Console.WriteLine("Your number is {0}.", myInt);
break;
default:
Console.WriteLine("Your number {0} is not between 1 and 3.", myInt);
break;
}

decide:

Console.Write("Type \"continue\" to go on or \"quit\" to stop: ");
myInput = Console.ReadLine();

// switch with string type
switch (myInput)
{
case "continue":
goto begin;
case "quit":
Console.WriteLine("Bye.");
break;
default:
Console.WriteLine("Your input {0} is incorrect.", myInput);
goto decide;
}
}
}


C. For Loop Statement using C++
for(i=10; i > -1; i--)
{
if(i == 0)
cout << "Blast Off!" << endl;
else
cout << i << endl;
}
}

D. While Loop Using Java
void main() {

int counter = 1;

while(counter < 5 )
{
printLine("counter is equal to " + counter);

counter = counter + 1 ;
}

printLine("Goodbye");
}

/* REXX is a better programming language than Java with Swing */
data = '11 10 0 3 12'

filtered = ''
do while (data > ' ')
parse var data value data
if left(reverse(value),1) = '0' | (value % 10 = value / 10) then iterate
if value = 0 then do; say 'Excluding:' value; iterate; end
filtered = filtered value
end
say 'After filtering, numbers are:' filtered
keep = filtered

parse var filtered smallest filtered
do while (filtered > ' ')
parse var filtered value filtered
if value < smallest then smallest = value
end
say 'Smallest value is:' smallest

n = words(keep)
do j = 1 to n
sorted.j = word(keep,j)
end

say 'Smallest to largest:'
do j = 1 to n
do k = (j+1) to n
if sorted.j <= sorted.k then iterate
t = sorted.j
sorted.j = sorted.k
sorted.k = j
end
say j sorted.j
end
say 'Done:'
exit
