How to pass a character to printf that was input by user in C?

I am just starting with C and trying to grasp the whole idea of pointers and I just came across the following issue.

I am trying to print out a character that was input by the user passing it to a separate function:

#define MAX_OPTION_INPUT 1
#define TRUE 1
#define FALSE 0


// print a menu
void getCharacter() {   
    char getNum[MAX_OPTION_INPUT+2];
    int finished = FALSE;

    // get character from user
    do {
        fgets(getNum, MAX_OPTION_INPUT+2, stdin);
        if (getNum[strlen(getNum) - 1] != '\n') {
            printf("Input one digit number please.\n");
            readRestOfLine();
      }
      else {
         getNum[strlen(getNum) - 1] = '\0';
         finished = TRUE;
      }
   } while (!finished);

    processChar(getNum);
}


// process menu
void processChar(char num) {
    printf("TADA: %c", num);
}

When I compile this code I get a warning: passing argument 1 of 'processChar' makes integer from pointer without a cast

And when I run it it prints out some weird character instead of the one that I supposed to pass.

Could you please explain to me where I am missing the point here? Thanks in advance!

Change the function to accept a char *:

void processChar(const char *num)
{
    printf("TADA: %s", num); /* %s instead of %c */
}

You're passing and using num as if it's a character when it's actually a character array.
