Add a contact function.

Delete a contact function

Find a Contact function segment

void Search_peo (PCon pCon)//Lookup function {char tmpname[name_max];int ret=0;printf ("Please enter the name you want to find:>"); scanf ("%s", tmpname); ret = Find (Pcon,tmpname), if (ret! =-1) {printf ("%s\t%s\t%d\t%s\t%s\t\n", Pcon->dhb[ret].name,pcon->dhb[ret].

Modify a Contact function segment

void Modify_peo (PCon pCon)//Modify data function {char tmpname[name_max];int ret=0;printf ("Please enter the name you want to modify:>"); scanf ("%s", Tmpname) ; ret = Find (Pcon,tmpname), if ( -1! = ret)//Find modified name after re-assignment {printf ("name:>"); scanf ("%s", (Pcon->dhb[ret]).

Show Contact function segment

void Show_peo (PCon pCon)//display function {int i;for (i=0;i<pcon->count;i++)//display and print said contact information {printf ("%s\t%s\t%d\t%s\t%s\t\ n ", pcon->dhb[i].name,pcon->dhb[i].sex,pcon->dhb[i].age,pcon->dhb[i].tele,pcon->dhb[i].addr);}}

Clear the Contact function segment

void Clear_peo (PCon pCon)//Clear all contact information {pcon->count = 0;}
