Sort the net pays (salary) using an array of pointers (do not change the data in the original array). For now, display only the net pays before sorting Sort the net pays (salary) using an array of pointers (do not change the data in the original array). For now, display only the net pays before sorting and after sorting.
My manager had me learn C++ basics and I made an entire payroll program using 5 employees. I first learned the main program, then functions, then average's, and sorting. Now the final part I have to do on this program that I've been working a month on now is Program 3 above. He wanted it due last week wed and this last part I'm having trouble with. Can somebody please help me out? Here's what I have with errors:

Here's what I have with errors:

8.) (Each undeclared identifier is reported only once for each function it appears in.)
9.)142 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `table' undeclared (first use this function)
I made an example program using pointers to sort:
#include<iostream.h>
int main(){
const int n=5;
int item[n]={2,5,3,1,8};
int *p[n];
int i,j;
int*temp;
int sortedflag=0;
for(i=0;i<n;i++) p[i]=item+i;//INITIALIZING POINTER ARRAY
for(i=0;i<n;i++)cout<<*p[i]<<" ";
while(!sortedflag){
sortedflag=1;
for(j=0;j<n-1;j++){
if(*p[j]>*p[j+1]){
temp=p[j];
p[j]=p[j+1];
p[j+1]=temp;
sortedflag=0; }//SWAP
}//J
}//I
cout<<endl<<"SORTED ARRAY: ";
for(i=0;i<n;i++)cout<<*p[i]<<" ";
system("PAUSE");
}//MAIN
Here's my "employee.txt" :
8572 42 12.00
6423 40 15.00
7465 45 10.00
2477 40 16.00
5996 44 18.00
I am on the right track I believe but I have some serious problems. How to I incorporate the sample program to make my payroll program work? Once it comes to additing it into a program full of functions I get confused. Can somebody please help me out? I've been working on this every night and I have to finish it. Thank you for anybody who replies
