I've googled this and it looks to me like what I am trying to do is impossible. I'm trying to write a Display function that can take different parameters and call the appropriate function based on those parameters (i.e. function overloading). I've read that C doesn't allow this, but I figured I'd post the code and see if anyone has anyone has any ideas. It compiles fine in C++. It compiles fine in C if I change it so no two functions have the same names (i,e. change the names to DisplayInt and DisplayIntArray ). Is that simply what I must do or is there a way to make it so the two functions have the same name?
#include <stdio.h>
#include <stdlib.h>
void Display (int* arr, int size);
void Display (int number);
int main ()
{
int* c;
int d;
int i;
int a[5];
int* b = (int*) malloc (5 * sizeof (int));
// initialize single integer and pointer
d = 6;
c = &d;
// initialize arrays
for (i = 0; i < 5; i++)
{
a[i] = 0x10 * i + 0xF;
b[i] = 0x10 * i + 0xB;
}
Display (a[2]);
printf ("\n");
Display (b[2]);
printf ("\n");
Display (d);
printf ("\n");
Display (*c);
printf ("\n");
Display (a,5);
printf ("\n");
Display (b,5);
printf ("\n");
free (b);
getchar ();
return 0;
}
// display an array of integers
void Display (int* arr, int size)
{
int i;
for (i = 0; i < size; i++)
{
Display (*(arr+i));
if (i < size - 1)
printf (", ");
}
}
// display a single integer
void Display (int number)
{
printf ("%08x", number);
}
