Answer:
The answer to this question is given below in the explanation section.
Explanation:
The iteration variable begins counting with 0 or 1.
As you know the iteration mostly done in the looping. For example, for loop and foreach loop and while loop, etc.
It depends upon you that from where you can begin the counting. You can begin counting either from zero or from one.
For example: this program counts 0 to 9.
<em>int total=0;</em>
<em>for(int i=0; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
Let's suppose, if you want to begin counting from 1, then the loop should look like below:
<em>int total=0;</em>
<em>for(int i=1; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
