Poor Programming

}

Where did i go wrong

The output must be something like this

MATERIALS
---------------------
Enter the cost of the following:
Paper : 0.25
Pencil : 5.00
Scissors : 25.00
Eraser : 2.50

PURCHASE
---------------------
How many items of the following did you buy?
Paper : 10
Pencil : 3
Scissors : 1
Eraser : 1

THE TOTAL PRICE IS 45.00
Enter Cash : 50.00
Return : 5.00

Please help, i need to submit this assignment on sixth day of july

Way Better and working without errors

# include<stdio.h>
# include<conio.h>
# define vat 1.12
int main ()
{
double pac, pec, scc, erc, te, cash, tpac, tpec, tscc, terc, ch, pretotal, postotal, posbtotal, posctotal, vatb;
int pa, pe, sc, er, ti;
printf("MATERIALS\n-------------------------------- \n");
printf("Enter the Cost of the Following:\n");
printf("Paper : ");
scanf("%lf", &pac);
printf("Pencil : ");
scanf("%lf", &pec);
printf("Scissors : ");
scanf("%lf", &scc);
printf("Eraser : ");
scanf("%lf", &erc);
printf("\nPURCHASE\n-------------------------------- \n");
printf("How many items of the following did you buy?\n");
printf("Paper : ");
scanf("%d", &pa);
printf("Pencil : ");
scanf("%d", &pe);
printf("Scissors : ");
scanf("%d", &sc);
printf("Eraser : ");
scanf("%d", &er);
tpac = pa*pac;
tpec = pe*pec;
tscc = sc*scc;
terc = er*erc;
pretotal = tpac+tpec+ tscc + terc;
printf("\nTOTAL : P %.2f\n", pretotal);
printf("Cash : P ");
scanf("%lf", &cash);
postotal = cash - pretotal;
printf("\nChange: P %.2f\n", postotal);
printf("Note: When negative, it means the customer has a credit or he has insufficient money to buy the items\n", postotal);
posctotal=pretotal/vat;
vatb=pretotal-posctotal;
printf("\nPrice before VAT: %.2lf", posctotal);
printf("\nVAT (12%): %.2lf", vatb);
getch();
return 0;
}

You are reading into your cash variable after printing it.
Beside that, the ending just isn't the same as the form, but I guess that's because you are testing stuff?

posctotal=pretotal/vat;
vatb=pretotal-posctotal;
printf("\nPrice before VAT: %.2lf", posctotal);
printf("\nVAT (12%): %.2lf", vatb);
getch();
return 0;
}

And i am able to fix it myself

Yes

You should probably give your variables more descriptive names in general.
If you want to print "%" in a formatted function such as printf, you should print "%%".

In the future, if you post code in C++ (or whatever language), please use the [highlight] tag.
E.g. [code=cpp]code[/code].

So this is the final ^_^ cant believe i cant make it
