I'm having a problem on passing a struct array to a function. Help me please.

I'm now getting closer to finishing my program but I am having a problem in outputting my inventory. What's wrong with my code?
(Our instructor told us not to touch those functions that she have given.)

You state on line 116 that 'temp' is a Products object. Products does not override operator[], so there is no reason to try such operation.

Who did wrote the signature of PDISPLAY? What is the purpose of the parameter 'sval'?

Looks like you need modify line 116 to

 
 
PDISPLAY(newProd, val);


and modify the delaration of PDISPLAY to

 
 
void PDISPLAY(Products *temp, int sval)


val, and hence sval, appear to be the number of Products' in the array newProd.
