I want to rewrite this line:
var mySum = myArray[0] + myArray[1] + myArray[2] + myArray[3];
Considering that I do not know a number of elements in the array, I am thinking of this:
for (var = count; count < array.length; count++)
{
var mySum = ?? // but what's the math for this
}
Seems like this:
var mySum = 0;
for( var i = 0, len = myArray.length; i < len; i++ ) mySum += myArray[ i ];
var mySum = 0;
for (var i=0; i < myArray.length; i++) mySum += myArray[i];
var mySum = 0;
var myArray = [1,2,3,5,8,13]
for(var i = 0,amount = myArray.length;i < amount;i++) {
mySum = mySum + myArray[i]
}
This is rather easy!
In your language it would look like
var mySum = 0;
for (var count = 0; count < array.length; count++) {
mySum += array[count];
// mySum = mySum + array[count]
// note that I declared mySum outside the loop
}
In something like java it would look like this
int[] array = new int[100];
int count = 0;
for (int i = 0; i < array.length; i++) {
count += array[i];
// i is the loop iterator
}
for (var = count; count < array.length; count++)
{
var mySum +=myArray[count];
}
var mySum = 0;
for (var i = 0; i < array.length; i++) {
var mySum += array[i];
}
var mySum = 0;
for (var = count; count < myArray.length; count++)
{
mySum +=myArray[count];
}
