# V6043\. Consider inspecting the 'for' operator\. Initial and final values of the iterator are the same\.

The analyzer has detected a potential error: initial and finite counter values coincide in the 'for' operator\. Using the 'for' operator in such a way will cause the loop to be executed only once or not to be executed at all\.

Consider the following example:

```cpp
void BeginAndEndForCheck(int beginLine, int endLine)
{
  for (int i = beginLine; i < beginLine; i++)
  {
    ...
  }
  ...
}
```

The loop body is never executed\. Most likely, there is a misprint and "i < beginLine" should be replaced with the correct expression "i < endLine"\. This is the correct code:

```cpp
for (int i = beginLine; i < endLine; i++)
{
  ...
}
```

Another example:

```cpp
for (int i = n; i <= n; i++) 
  ...
```

This loop's body will be executed only once\. This is probably not what the programmer intended\.
