    How to test for a char when reading and int on a loop

    I normally use a code like this to read and int between some range:
    Code:
    do {
    		printf("Integer: ");
    		scanf("%d%*c", &value);
    	} while(value < 1 || value > 10);
    But suppose I input something not a digit... this will go into a loop printing "Integer :" and will not end until I Ctrl+C or Ctrl+Z. How can I ask the user to input again if he did not inputed a digit on the first place?

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
