V589. The expression of the 'A =- B' kind is utilized. Consider reviewing it, as it is possible that 'A -= B' was meant.
The analyzer detected a potential error: there is a sequence of '=-' characters in code. It might be a misprint and you should use the '-=' operator.
Consider this sample:
size_t size, delta; ... size =- delta;
This code may be correct, but it is highly probable that there is a misprint and the programmer actually intended to use the '-=' operator. This is the fixed code:
size_t size, delta; ... size -= delta;
If the code is correct, you may type in an additional space between the characters '=' and '-' to remove the V589 warning. This is an example of correct code where the warning is not generated:
size = -delta;
To make false reports fewer, there are some specific exceptions to the V589 rule. For instance, the analyzer will not generate the warning if a programmer does not use spaces between variables and operators. Here you are some samples of code the analyzer considers safe:
A=-B; int Z =- 1; N =- N;
Note. To search for misprints of the 'A =+ B' type, the V588 diagnostic check is used.
This diagnostic is classified as:
