V3020. An unconditional 'break/continue/return/goto' within a loop.
The analyzer has detected a suspicious loop where one of the following statements is used: continue, break, return, goto, or throw. These statements are executed all the time, irrespective of any conditions.
For example:
while (k < max)
{
if (k == index)
value = Calculate(k);
break;
++k;
}In this code, the 'break' statement doesn't belong to the 'if' statement, which will cause it to execute all the time, regardless of whether or not the 'k == index' condition is true, and the loop body will iterate only once. The correct version of this code should look like this:
while (k < max)
{
if (k == index)
{
value = Calculate(k);
break;
}
++k;
}This diagnostic is classified as:
