assignment within conditional expression
The test value in a conditional expression was the result of an assignment.
This warning is informational.
An assignment has a value (the value on the left side of the assignment) that can be used legally in another expression, including a test expression. However, the intention may have been to test a relation, not to make an assignment.
For example, the following line, which generates this warning, assigns b to a and compares the value of a with 0:
if ( a = b ) ...
However, the following line tests whether a and b are equal:
if ( a == b ) ...
