C PROGRAMMING: I'm getting errors for this...how can I fix it? I also need to add a FOR loop so that the program keeps asking to enter an int and char...until you enter -10000 as the int and any character for ch. Please help.

THESE ARE THE INSTRUCTIONS FOR THE QUESTION:

1.2 Implementation

name your program lab2A.c

keep on reading and processing input, until an integer -10000 is read.

use scanf ("%d %c", ..) to read inputs. define a Boolean function isDigit(char c) to determine if c represents a digit. We mentioned in class that ANSI-C does not have a type `boolean, instead it uses 0 to represent false, and use non-zero integer to represent true. So, as a general practice in C, your function should return a non-zero number (usually 1) if c is a digit and returns 0 otherwise. Note that you should NOT use if c=='0' c=='1' c=='2' c=='3' c=='9'. Instead, use the one-statement trick that we discussed in class.

Note that in getting the numerical value of a digit character such as '3', you should NOT use if c=='0' c=='1' c=='2' c=='3' c=='9'. Instead, use the onestatement trick that we discussed in class.

put the definition (implementation) of function isDigit after your main function.

display the prompt and output as shown below.
