Question
I need to make an array for priceList but do not know how to go about doing so :( This is what is being asked to be used as the user defined function.
//takes an array of all the purchase transaction costs
//and the number of items purchased
//and displays the information onto the screen
void DisplayPurchases(double priceList[ ], int num);
This is what i already have written for the selection and 'cost' values which i want to be set in a priceList array.
void DisplayApps(char *selectionPtr)
{
char selection;
printf("HERE ARE THE SELECTIONS: C -- Cyber Tuner $999.99 V -- VIP Black $1,199.99 W -- Water Globe $219.99 B -- BeFunky Express $4.99 M -- Mobile Cam Viewer $349.99 ");
printf("Please enter a selection: ");
scanf("%c", &selection);
SetCost(selection);
}
void SetCost(char selection, double *costPtr)
{
switch (toupper(selection))
{
case 'C':
printf(" The item costs $999.99 ");
cost = 999.99;
break;
case 'V':
printf(" The item costs $1,199.99 ");
cost = 1199.99;
break;
case 'W':
printf(" The item costs $219.99 ");
cost = 219.99;
break;
case 'B':
printf(" The item costs $4.99 ");
cost = 4.99;
break;
case 'M':
printf(" The item costs $349.99 ");
cost = 349.99;
break;
default:
printf("Choose the selections given! ");
break;
}
}
