V619. Array is used as pointer to single object.

Jul 03 2012

The analyzer has detected that the '->' operator is applied to a variable defined as a data array. Such a code might indicate incorrect use of data structures leading to incorrect filling of the structure fields.

Consider a sample of incorrect code:

struct Struct {
  int r;
};
...
Struct ms[10];
for (int i = 0; i < 10; i++)
{
  ms->r = 0;
  ...  
}

Using it in this way is incorrect, as only the first array item will be initialized. Perhaps there is a misprint here or some other variable should be used. This is the correct code:

Struct ms[10];
for (int i = 0; i < 10; i++)
{
  ms[i].r = 0;
  ... 
}

This diagnostic is classified as:
