i have a piece of an unfinished program.
try to run it...
if you go straight to option 3 and input values, how do i output these values in option 4 ?
i tried outputting my declared variables
it wont work ? why is this ?
i apologize the code is so long

I hope someone can tell me how i'd go about it

#include <iostream>  				//the usual headers are used including string
#include <string>
#include <conio.h>

void WeeklySales(); 									//these are functions i created

i guess i'm trying to say; how do i output values from one case within a switch statement to another ?

double sales, sales_amount, quantity, total_sales, vat;

Your redeclaration is not in the scope of the main function .

i have a piece of an unfinished program.
try to run it...

No. If you post readable code, we can follow it. Please format your code cleanly and consistently. See this.

if you go straight to option 3 and input values, how do i output these values in option 4 ?
i tried outputting my declared variables
it wont work ? why is this ?

By not declaring them only during option 3. Once option 3 is done, the variables are destroyed. Define them at the beginning of main() .

i apologize the code is so long

Then just post the relevant section of code. Then, no need to be sorry, and we don't have to search so much. :icon_wink:

thanks

ok, i have reformatted my code and sorted out my issue. For all those who were unhappy.
I now have a new problem, how would i output the commission value in case 4? (line 107).
here i have tried using

cout << "\n5% commission of total sales is " << commission = 0.05 * total_sales << "\n\n\n";

to assign commission a value, but i get the error

illegal use of floating point.

Any ideas?

i dunno, when i post my code on here it changes up.
Trust me i reformatted it. :p
