bool & scanf

[howa]

Hi,

How to accept bool value from stdin, using scanf?

e.g.

bool b ;
scanf_s("%d", &b);

It will show:

Unhandled exception at 0x0040a083 in MSFT.exe: 0xC0000005: Access
violation writing location 0xffffffe4.


Thanks.

scanf can not read into boolean, you have to read into an int (or
similar) and then convert the value to bool (or you can read in a string
and convert the text to bool).
