           scanf("%d", &qty);
          
           switch(code)
           {
               case 1: price = 150.00;
                             break;
               case 2: price = 180.00;
                             break;
               case 3: price = 200.00;

Dapat i-implement mo hash para sa item:cost para mas matibay yung relation. Pwede ka gumami ng struct para dito. Tapos array ng structs (which is yung hash ng item:cost). Like sa baba yung sa line# 4.

Tapos sa line#57-68 yung array ng structs (o yung item:cost).

Sa pagkuha ng user input, mapapansin mo combination ng getline at sscanf yung ginamit ko kase mas safer yan kesa sa scanf (which is dangerous).

Yung switch code mo, walang strong relation yun sa item na prone sa mis-pairing.
