Can't input in x86 environment, but can be direct assignment;
Under the environment of x64 can input, this is out of memory? But all is a byte!

If you have a good look at documentation scanf_s parameter is wrong, should have a parameter specifies the length of the
Scanf_s (" % c ", & amp; A, 1);

do you have a good look at documentation scanf_s parameters is wrong, should have a parameter specifies the length of the
Scanf_s (" % c ", & amp; A, 1);

Seemed to say, I won't try to work now, you said scanf_s (" % c ", & amp; 1 a, 1) is to specify the length of the character?

Enter a single character char to specify length, too?

If the specified length continuous input is also used after the getchar () to absorb the enter key
