if i've understood you correct that's the code yo initialise all jobs in array

Code:
typedef struct
{
char name[10];
int bas_hp;
int bas_att;
int bas_def;
int bas_acc;
int bas_eva;
} JOB;

JOB job[500];

void job_init (JOB* jb)
{
jb.name = "Thief";
jb.bas_hp = 9;
jb.bas_att = 4;
jb.bas_def = 3;
jb.bas_acc = 6;
jb.bas_eva = 3;
}

void init_all_jobs()
{
var num = 0;
while(num<499)
{
job_init (job[num]);
num+=1;
}
}
