Analyzer detected a potential error concerning the senseless mutual assignment of variables.
Let's review an example:
int A, B, C;
...
A = B;
C = 10;
B = A;Here the assignment "B=A" lacks any sort of practical utility. It is possibly a misprint or just an unnecessary operation. The correct code:
A = B;
C = 10;
B = A_2;An example stated above is a synthetic one. Let's see how such an error could appear in the source code of a real-life application:
// Swap; exercises counters
{
RCPFooRef temp = f2;
f2 = f3;
f3 = f2;
}The correct code:
// Swap; exercises counters
{
RCPFooRef temp = f2;
f2 = f3;
f3 = temp;
}You can look at examples of errors detected by the V587 diagnostic. |
