Errors calling function

When I compile, I get these errors:

Code:

---

44 C:\Documents and Settings\xxxxx\My Documents\School\cis111\projects\d4test.c [Warning] passing arg 1 of `print_ssnum' makes integer from pointer without a cast

---

Code:

---

44 C:\Documents and Settings\xxxxx\My Documents\School\cis111\projects\d4test.c invalid use of void expression

---

I guess I dont see whats wrong with this code:

Code:

---

#include <stdio.h>
#include <stdlib.h>

int change(char *before) {
   
    int after = 0;
    char *end;

    after = strtol(before, &end, 0);
    after = (after * 100) + strtol(end + 1, &end, 0);
    after = (after * 10000) + strtol(end + 1, &end, 0);

    return after;
}

void print_ssnum(int pc) {
 
    printf("%2d-%4d-%2d\n", pc / 1000000, pc / 10000, pc % 10000);
}

void main (void) {

    struct student {
         
        int grad_year;        /* members defined here */
        char ........n, *dob, name[40], curr[4];
    };
   
    struct student    s;
    struct student    *sp;

    s.grad_year = 2010;
    s.ssn = "142-76-6900";
    s.dob = "11/17/1975";
    s.name;
    s.curr;
         
    sp = malloc (512 * sizeof(struct student));        /* Allocate memory 50 times 4 bytes wide */
    strcpy(s.name, "Douglas W Van Allen");
    strcpy(s.curr, "CIS");
    *s.ssn = change(s.ssn);
    *s.dob = change(s.dob);
    printf("Cotents of s:\nName of Student = %s\nSocial Security Num = %d\nDate of Birth = %d\nCurriculum = %s\nGraduation year = %d\n",
          s.name, print_ssnum(s.ssn), s.dob, s.curr, s.grad_year);
   
   
   

    if (sp == NULL) {        /* If memory can't be allocated */
         
        printf("Cannot malloc\n");
        exit(1);
    }
    free (sp);
}

I don't even see printpc in your code.

Changed. Older compile log.

Well, the problem is that s.ssn is a pointer to type char and print_ssnum() expects an int.

>print_ssnum(s.ssn)
ssn is not defined in your structure (you have lots of dots in there though!?)
What is it?
The function print_ssum() requires an int as a parameter, if ssn isn't an int, then the compiler will complain.
