In c programming, i would like to use typedef struct to input the data of each visitor.(Eg, visitor1's name ,id, arrival, key, night price). I wanted to input those data with scanf but it doesn't work. Besides, another structure \"updated\" is used for renew the key, night,breakfast , and price.If one of them are updated. Thanks!

typedef struct _visitor char *name; char *id; int arrival; int key int night; int price; Ivisitori struct visitor update (struct visitor,int a,int b); int main() int noofvisitor,i,*p; visitor a= { ali, A123, 180118, 1,1,1): p &b.key: printf(no of visitors:); scanf (%d, &noofvisitor) ; print f(%s %s %d %d %d %d , a. name, a.id, a. arrival, a .key, a. night, a . price); scanf (name of visitor b: %d,p); print f ( name of visitor b: %s,b.name);\" v:shapes=\"Picture_x0020_1\">
