Domino Program Issues - c

Question

I am trying to get this code done quickly for class as I have already been writing it for upwards of 10 hours and I just can't get it to work. Essentially what it is, is a domino program where you enter the first number of the domino, the second number, and then a flag (y will be standard- will have to switch to n when dice is removed). Currently I am receiving errors stating the following:
1. warning: format '%c' expects argument of type 'char ', but argument 2 has type 'void() ()'
2. error: called object 'print' is not a function
3. error: expected expression before 'Domino'
I have sat and researched this issue for hours online and I know I am missing something small. Any assistance would be greatly appreciated
#include <stdio.h>
#include <stdlib.h>
int getIndex();
void addDomino();
void removeDomino();
void print();
void quit();
typedef struct Domino{
int * i;
int * x;
int * y;
}Domino;
int main(int argc, char * argv[])
{
int NumDom, DomNum1, DomNum2, DomIndex, Index, input;
char MainMenu;
//Startup
printf("Enter the max number of dominos:");
scanf("%d",&NumDom);
void * add = malloc(size(Domino)*1);
void * remove = malloc(offset(Domino)*1);
void * print = malloc(sizeof(Domino)*10);
//int domino[NumDom][3];
//int dom[0][3] = {Index, DomNum1, DomNum2};
//Main Menu
// printf("Enter (p) to print (a) to add (r) to remove and (q) to quit\n");
// printf(":");
// scanf("%s",&MainMenu);
printf("Enter (p) to print (a) to add (r) to remove and (q) to quit\n");
scanf("%c%c%c%c \n", addDomino, removeDomino, print, quit);
switch(input)
{
case 'a':
addDomino();
break;
case 'r':
removeDomino();
break;
case 'p':
print();
break;
case 'q':
quit();
break;
printf(":\n");
}
}
//Add
void addDomino(DomNum1, DomNum2)
{
printf("Enter number 1\n");
printf(":");
scanf("%d", &DomNum1);
printf("Enter number 2\n");
printf(":");
scanf("%d", &DomNum2);
}
//Print
void printDomino(DomNum1, DomNum2)
{
printf("Printing Dominos\n");
printf("Domino # (%d,%d)\n",DomNum1,DomNum2);
}
//Remove
void removeDomino(DomIndex)
{
printf("Enter the index:%d", DomIndex);
scanf("%d", &DomIndex);
}
//Quit
void quit()
{
printf("All done\n");
}
HERE IS THE ORIGINAL CODE THAT WORKS MINUS ALL MY FUNCTION ISSUES
#include <stdio.h>
#include <stdlib.h>
typedef struct Domino{
int * i;
int * x;
int * y;
}Domino;
int main(int argc, const char * argv[])
{
int NumDom, DomNum1, DomNum2, DomIndex, Index;
char MainMenu;
//Startup
printf("Enter the max number of dominos:");
scanf("%d",&NumDom);
//int domino[NumDom][3];
//int dom[0][3] = {Index, DomNum1, DomNum2};
//Main Menu
printf("Enter (p) to print (a) to add (r) to remove and (q) to quit\n");
printf(":");
scanf("%s",&MainMenu);
//Add
printf("Enter number 1\n");
printf(":");
scanf("%d", &DomNum1);
printf("Enter number 2\n");
printf(":");
scanf("%d", &DomNum2);
//Print
printf("Printing Dominos\n");
printf("Domino # (%d,%d)\n", DomNum1, DomNum2);
//Remove
printf("Enter the index:5");
scanf("%d", &DomIndex);
//Quit
printf("All done\n");
}

Answer 1

As for the first issue - you're passing function pointer to scant function, I don't understand what you're trying to achieve.
Just give it input variable and that's all.

Answer 2

Your problem is that you're telling scanf to scan for a character, but you're not giving it a character to put the value into. For example, this:
printf("Enter (p) to print (a) to add (r) to remove and (q) to quit\n");
scanf("%c%c%c%c \n", addDomino, removeDomino, print, quit);
Makes no sense. You're asking the user to pick a command but asking for 4 characters to be entered. You just need something like this:
char command;
printf("Enter (p) to print (a) to add (r) to remove and (q) to quit\n");
scanf("%c", &command);
You've also not typed the parameters to your functions. For example this:
void addDomino(DomNum1, DomNum2)
looks like it ought to be this:
void addDomino(int DomNum1, int DomNum2)
and at the top, where you had this:
void addDomino()
it should look like this:
void addDomino(int, int)
This will allow you to call addDomino() from inside main().
