displaying values in c structure array - c

Question

I'm trying to display the values of my structure array, the compiler throws out the following error:
athletes.c:17: error: expected ')' before '*' token
Could someone help me out with a solution and if possible an explanation as to what I did wrong.
#include <stdio.h>
#include <string.h>
struct athlete {
char last_name[25];
char first_name [20];
int rank;
float salary;
};
int main (void) {
struct athlete players[] = {{"Lebron", "James",1,25}, {"Durant", "Kevin",3,20},{"Duncan","Tim",2,12}};
display_jock(players);
}
void display_jock(athlete *p) {
printf ("%10c%10c%10d%10.1f \n", p[0].last_name,p[0].first_name,p[0].rank, p[0].salary);
printf ("%10c%10c%10d%10.1f \n", p[1].last_name,p[1].first_name,p[1].rank, p[1].salary);
printf ("%10c%10c%10d%10.1f \n", p[2].last_name,p[2].first_name,p[2].rank, p[2].salary);
}

Answer 1

there are several small errors:
your code does not know the type "athlete", so your class display_jock should be defined with argument struct athlete: void display_jock(struct athlete *p)
you should forward declare that function: otherwise main doesn't know it (edit:you could also just move the display_jock function at the top of the main function)
when printing a char array, you should use %s instead of %c when using printf.
your main function should return an int (since it is declared as int main...)
this is your code fixed up:
#include <stdio.h>
#include <string.h>
struct athlete {
char last_name[25];
char first_name [20];
int rank;
float salary;
};
void display_jock(struct athlete *p);
int main (void) {
struct athlete players[] = {{"Lebron", "James",1,25}, {"Durant", "Kevin",3,20},{"Duncan","Tim",2,12}};
display_jock(players);
return 0;
}
void display_jock(struct athlete *p) {
printf ("%s%s%10d%10.1f \n", p[0].last_name,p[0].first_name,p[0].rank, p[0].salary);
printf ("%s%s%10d%10.1f \n", p[1].last_name,p[1].first_name,p[1].rank, p[1].salary);
printf ("%s%s%10d%10.1f \n", p[2].last_name,p[2].first_name,p[2].rank, p[2].salary);
}
