I have below class
class Cdata12Mnt
{
public:
char IOBname[ID1_IOB_PIOTSUP-ID1_IOB_TOP][BOADNAM_MAX + 4];
char ExIOBname[ID1_MAX_INF-ID1_EXIOB_U1TOP]
As a side-note, you can enable/disable individual warnings using #pragma. You can have a look at the documentation here
From the documentation:
// pragma_warning.cpp
// compile with: /W1
#pragma warning(disable:4700)
void Test() {
int x;
int y = x; // no C4700 here
#pragma warning(default:4700) // C4700 enabled after Test ends
}
int main() {
int x;
int y = x; // C4700
}
