V621. Loop may execute incorrectly or may not execute at all. Consider inspecting the 'for' operator.
The analyzer has detected a potential error: odd initial and finite counter values are used in the 'for' operator. It may cause incorrect loop execution and break the program execution logic.
Consider the following example:
signed char i;
for (i = -10; i < 100; i--)
{
...
};Perhaps there is a misprint here causing the initial and finite values to be mixed up. The error may also occur if operators '++' and '--' are mixed up.
This is the correct code:
for (i = -10; i < 100; i++)
{
...
};The following code is also correct:
for (i = 100; i > -10; i--)
{
...
};Consider the following code sample found by the analyzer in a real application:
void CertificateRequest::Build()
{
...
uint16 authCount = 0;
for (int j = 0; j < authCount; j++) {
int sz = REQUEST_HEADER + MIN_DIS_SIZE;
...
}
}The 'authCount' variable is initialized by an incorrect value or perhaps there is even some other variable to be used here.
