V588. The expression of the 'A =+ B' kind is utilized. Consider reviewing it, as it is possible that 'A += B' was meant.

Aug 31 2011

The analyzer detected a potential error: there is a sequence of '=+' characters. It might be a misprint and you should use the '+=' operator.

Consider the following example:

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 this code is correct, you may remove '+' or type in an additional space to prevent showing the V588 warning. The following is an example of correct code where the warning is not generated:

size = delta;
size = +delta;

Note. To search for misprints of the 'A =- B' kind, we use the V589 diagnostic rule. This check is implemented separately since a lot of false reports are probable and you may want to disable it.

This diagnostic is classified as:
