struct problem

[SarahYan]

Could someone please help me with this? Why is yearofstart value not printed out in the first argument ? I knw there is something wrong, but I don't knw what is it :)
Thanks so much.

#include <stdio.h>

struct date{
int year;
}yearofstart={1950};

struct record{
char *name;
char acct_type;
struct date yearofstart;
}customer={"Jones",'A'};

void adjust(struct record *ptr);
int main(){

printf("%s %c %d \n",customer.name,customer.acct_type,customer.yearofstart.year);

adjust(&customer);

printf("%s %c %d \n",customer.name,customer.acct_type,customer.yearofstart.year);
return 0;
}

void adjust(struct record *ptr){

ptr->name="Mike";
ptr->acct_type='B';
ptr->yearofstart.year=1999;
}

The yearofstart member of struct customer variable does not bear a relation to struct yearofstart variable. You don't initialize this last (of struct date type) member of customer. It's a global variable so all its members initialized with 0.

It's because of the scope of yearofstart declared inside the struct record lies only within that structure. If you want your program to print 1950, do this:

struct record{
char *name;
char acct_type;
struct date yearofstart;
}customer={"Jones",'A',1950};

Or do this:

printf("%s %c %d \n",customer.name,customer.acct_type,yearofstart.year);
