it prints the ascii value of last digit.

char a = '12';

In location a first ascii value of 1 will be stored and then it will be over written by ascii value of 2.

Now at location a  ascii value of 2 is present.

If we try to print it :  %d will return 50 which is ascii value of 2

                               %c will print 2
