Hi all,

Here is a homework problem I'm currently stuck half way through. The problem is to shift the stored value of five character variables (i.e. ABCDE becomes BCDEA, etc.). I have the call function but now I'm stuck on how to call it five times. Here is what I have:

void shift(char *p1, char *p2, char *p3, char *p4, char *p5)
{
char temp;
char p1 = 'A', p2 = 'B', p3 = 'C', p4 = 'D', p5 = 'E';
temp = *p1; *p1 = *p2; *p2 = *p3; *p3= *p4; *p4 = *p5; *p5 = temp;
}

This is under "callfunction.c". I believe I should have another file named main.c which calls it.

Any help?

I'm not exactly sure what your asking for, but if you don't have a main function you'll need that... so:
CODE

#include <iostream>
#include "callfunction.c"

int main(void)
{
   char a(A), b(B), c(C), d(D), e(E);

   for(int i(0); i<5; i++)
   {
       shift(&a, &b, &c, &d, &e);
   }

   return(0);
}


this would be in your main.cpp or main.c file, etc.

If you need to shift all the characters ..
please increment each of them by one ..

CODE

int main()
{
char a='A',b='B';
shift(&a);
shift(&b);
}

void shift(char *a)
{
  *a = *a + 1;
}
