just use fflush(stdin) to flush the input buffer so that it can show
the prompt for the next character.
eg.
printf("Enter a ");
scanf("%c",&a);
fflush(stdin);
printf("Enter b ");
scanf("%c",&b);
fflush(stdin);
printf("b= %c\n",b);
return 0;

I can't believe we have had two suggestions in 24 hours that people use
undefined behavior. Please learn: "fflush() is not defined on input
streams."

We are told in the Lunyu (13.3) that Zilu put a silly claim to Kongzi.
Master Kong replied "How can you be so dense? Where an exemplary man is
ignorant, one should expect him to offer no opinion." This is a maxim
you should inscribe on your forehead. Or you could look up one of Dan
Pop's more colorful expressions of the same idea.

Do it yourself...

Now you understand better why scanf() is for gurus only. Mean
programmers use fgets().
