//SOME PRACTICE PROBLEMS
//FOR COMS 161.02
//WEDNESDAY NOVEMBER 19th

//DETERMINE THE EXACT OUTPUT OF
//THE FOLLOWING PROGRAMS.  


//#1
sum = 0;
number = 10;

while (number > 4) {
  sum += number;
  number = number - 2;
  alert("number = " + number);
}

//#2 PREDICT WHAT WILL HAPPEN IF YOU
//   ENTERED 20, then 5, then 4, then 3, then 0 
//   WHEN PROMPTED 

count = 0;
n = prompt("Enter a number");

  if (n % 2 == 1)
    count++;
  else
    alert("n = " + n);

  alert("count = " + count);

  n = prompt("Enter a number: ");
}


//#3 PREDICT THE EXACT OUTPUT

sum = 0;
i = 0;
N = list.length;

while (i < N) {
  if (list[i] > 10) {
    sum += list[i];
    alert("i = " + i + " sum = " + sum);

//#4 PREDICT THE EXACT OUTPUT

while (list[i] < 20) {
    sum += list[i];
    i++;
}

alert("i = " + i + " sum = " + sum);


//#5 PREDICT THE EXACT OUTPUT

list = new Array("Bob", "Ted", "Bill", "Joe", "Jo", "Jill", "Barb");

while (list[i].length > 2) {
  sum += list[i].length;

//#6 WRITE A PROGRAM THAT WILL REPORT THE SMALLEST NUMBER IN AN ARRAY
//  AND ALSO HOW MANY TIMES THAT NUMBER OCCURRED
