Unused Value
Warning
New
Last modified: 03 December 2024Reports the variable values that are never used after being assigned. This can happen in the following cases:
the variable is never read after the assignment
the value is overwritten by another assignment before it is accessed for reading
the variable initializer is redundant (for one of the above two reasons)
the variable itself is never used.
Example:
class C {
int field;
void foo() {
field = unused_value;
}
void bar() {
use(field);
foo();
}
};
