hi guys im trying to come over this problem but i think i lack some knowledge and i am stuck to this code.
all i want is that the user enters the number from 1-6 whatever he wants to do..but for now just option 2 input data...
after selecting 2 he will get to a loop because i want that whenever he types cancel it goes up to the main menu..
now it should work like the user selects 1-6 and assuming he selects 2 and now he enters store name in this case they are only 2(lambton and callaghan).

if the user enters a third name the program shows no such store found ...
but this code is crazy...i enter lambton and it says no such store found..
can someone rectify the prob.?

anyone ?

Line 71 - you have selection = 2, needs to be selection == 2.

You don't really need the lower function - just use stricmp or strcasecmp depending on your compiler - it is the case insensitive comparison.

You have weird logic in lines 78-85. It should be removed. Your code should look more like:

1
2
3
4
5
6
7
 
if ( strcmp (storeinput,store1) ==0 ) {
  // ... lambton
} else if ( strcmp (storeinput,store2) ==0 ) {
  // ... callaghan
} else {
  // No store found
}


Good luck!

EDIT: Oh by the way, this strcmp(cancel,storeinput)!=0 || strcmp(cancel,productinput) !=0 should be changed to strcmp(cancel,storeinput)!=0 && strcmp(cancel,productinput) !=0 in line 113

Thanks alot buddy ! that was a silly mistake.
i have to use lower function beacause it is in the assignment requirments !
seehat (28)
from line 92-103

as u can see buddy i have to ask for the products info each time (i have 5 products and each product has 6 data's to store...

i am willing to make a function so i can call it everytime i need to take the inputs...
im finding it difficult because each product will have different name of memory i want to store it to.. like lambton.coffee.sellingprice , lambton.tea.unitcost , callaghan.pie.weeks etc.

can you give me an idea how u think i can deal with it ? :)
thanks again.
seehat (28)
Anyone????
KRAkatau (197)
Well, while all this is still far from "nice" code, you could make a function like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
void ReadProduct(const char* productName, product_t& product)
{
  printf("Please, input the demand rate of %s: >", productName);
  scanf("%d",&product.demandrate);
  printf("Please, input the setup cost of %s: >", productName);
  scanf("%d",&product.setupcost);
  printf("Please, input the unit cost of %s: >", productName);
  scanf("%d",&product.unitcost);
  printf("Please, input the inventory cost of %s: >", productName);
  scanf("%d",&product.inventorycost);
  printf("Please, input the selling price of %s: >", productName);
  scanf("%d",&product.sellingprice);
  printf("Please, input the number of %s: >", productName);
  scanf("%i",&product.weeks);
}


and then call it like this:
1
2
3
4
5
6
 
if( strcmp (productinput,coffee) ==0) {
  ReadProduct(coffee, lambton.coffee);
} else if ( strcmp (productinput,chocolate) ==0) {
   ReadProduct(coffee, lambton.choc);
}
...
KRAkatau (197)
BTW, I assume return in line 105 is there just for testing. Aaand the condition in line 145 is still wrong. It doesn't really matter because of the break statements. You should change it to either the one I showed in previous post or to while(true).
seehat (28)
Thanks Bro !
in line 105 i used return(0) because once the operations in that loop is finished it goes up to the main menu.. i didnt wanted that.
yeh i changed in to while(true) bro !

i knew something like this will be done but didnt find examples on the forum!
bro im unclear of what this function header doing
i know we giving two values one is productname(coffee,choc,tea) and other is lambton.productname
can u please elaborate about the header ?
thanks big time !
