B) Loop control Variable
Explanation:
When programming, A loop control variable is used to control the number of iterations for a program loop. By convention programmers love to call this variable counter, i, j, n etc. The control variable when defined will determine the number of times a loop will execute. See the example bellow in C++ where we use a for loop to print the word "Hello" 5 times
<em>#include <iostream></em>
<em>using namespace std;</em>
<em>int main()</em>
<em>{</em>
<em> for(int counter = 0; counter<5; counter++){</em>
<em> cout<<"Hello"<<endl;</em>
<em> }</em>
<em> return 0;</em>
<em>}</em>
In this code snippet, the control variable is called counter and the condition is that counter will run from 0 to 4. So we get the world Hello printed five times
