c++.beta - Bug: 'Warning 12: variable used before set' error
- Amnon Loeza (19/19) Dec 02 2003 typedef struct AB {
typedef struct AB {
int a;
int b;
} AB;
void func(AB *pAB, int count)
{ AB temp;
for (count--; count>=0; count--) {
temp = pAB[ count ];
temp.a /= 2; /* (A) */
temp.b /= 2; /* (B) */
pAB[ count ] = temp;
}
}

The compiler gives a "Warning 12: variable 'struct AB temp' used before set"
warning for the code listed above.
No data for member a is copied into variable 'temp'; temp.a (line (A)) contains
unknown data. This is not the case for line (B).
It seems that only the first member of a structure isn't copied.
