c - Expected expression before error -

i've been working on project while , wanted test it, keep getting error , have no idea , confused. here code:

    typedef struct{        int nr_pages;        int id;        int a,b;         int aux;     }information;      int main(){      int i;      = information.b;      //and more stuff happens     }  

the error getting "expected expression before 'information'" declare = information.b doing wrong?

you need instantiate structure before using it. try:

typedef struct{    int nr_pages;    int id;    int a,b;     int aux; }information;  int main(){   information info;  info.b = 0;  info.a = 0;  ...  etc  ...   int = information.b;  //and more stuff happens }
