warning C6292: ill-defined for-loop: counts up from maximum

This warning indicates that a for-loop might not function as intended.

It occurs when a loop counts up from a maximum, but has a lower termination condition. This loop will terminate only after integer overflow occurs.

Example

The following code generates this warning:

void f( )  
{  
   int i;  
  
   for (i = 100; i >= 0; i++)  
   {  
      // code ...  
   }  
}

To correct this warning, use the following code:

void f( )  
{  
   int i;  
  
  for (i = 100; i >= 0; i--)  
   {  
      // code ...  
   }  
}
