Lab exercise 4

1.
Paste this program into the compiler and get it to compile.


include [iostream]

using namespace standard

main {
  float i,
  float j;
  character ch;

  cout << Enter a number: << endl;
  cin << i;
  i + i = j;
  if (j =< 10)
    cout << j << endl
  else {
    for k=0: k<5: k++
      cout << k;
    cout << endl;
  }



2.
Write a program that inputs two integers from the user.
The two values must be both greater than 0, and the first must be less
than the second.  (The code must do input data validation
error-checking loop).
Display the two valid integers.


3.
Write a program that will display a "wavy line" going down the
screen.  The output will look something like this:
*
 *
  *
   *
  *
 *
*
 * 
  *
   *
  *
 *
*
forever.  You can vary the "width" of the line.
The display will be very fast to really see the "waving", so slow it
down by simultaneously running another program that infinte loops
doing nothing, warming the cpu:

int main() {
  while (true)
    ;
}

(the standard incantations aren't needed, this is the complete program)
 Bring up Task Manager (Ctrl Shift Esc) to see that the CPU is pegged
 at 100%.
