# V625\. Initial and final values of the iterator are the same\. Consider inspecting the 'for' operator\.

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 be executed at all\.

Consider the following example:

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

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

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

Another example:

```cpp
for (size_t i = A; i <= A; ++i) 
  ...
```

This loop's body will be executed only once\. This is hardly what the programmer intended\.
