Although my program gives the required output. There are many warnings showing scanf() shouldn't be used and try using scanf_s() instead.
Possible cause of this warning??
This is happening to all the programs which are using the scanf function. Even simple addition of numbers.
With scanf, with some format arguments it is possible to crash your program if you use unlimited size inputs. scanf_s requires to provide size of output buffers, thus limiting possibility of buffer overflows (provided you specify output buffer sizes correctly).
