private:
int x, y;
public:
A(int X = 0, int Y = 0) :x(X), y(Y)
{
cout << "A Constructor" << endl;
}
A(A& a)
{
x = a.x; y = a.y;

我在C中有以下代码
long from = atol(buffer);
printf("From: %ld\n", from);
int file_fd = open(fullPath, O_RDONLY);
if (file_fd == -1) error("Error opening file");
if (from > -1)
{
int a = lseek(file_fd, from, SEEK_SET);
if (a == -1)
error("Error in lseek");
}
中的错误
