putting value of struct in runtme

C
my struct operations

C offers you:

struct initialization (only at declaration time):

struct Student s1 = {1, "foo", 2.0 }, s2;
struct copy:

struct Student s1 = {1, "foo", 2.0 }, s2;
s2 = s1;
direct element access:

struct Student s1 ;
s1.id = 3;
s1.name = "bar";
s1.score = 3.0;
manipulation through pointer:

struct Student s1 = {1, "foo", 2.0 }, s2, *ps3;
ps3 = &s2;
ps3->id = 3;
ps3->name = "bar";
ps3->score = 3.0;
initialization function:

void initStudent(struct Student *st, int id, char *name, double score) {
    st->id = id;
    st->name = name;
    st->score = score;
}
...
int main() {
    ...
    struct Student s1;
    iniStudent(&s1, 1, "foo", 2.0);
    ...
}
