Explanation / Answer

//fruitshop.cpp ,c++ code read input from inventory.txt and output in total.txt

#include <iostream>
#include <stdlib.h>
#include <stdio.h>

using namespace std;

int main()
{
FILE *rptr=fopen("inventory.txt","r");   //reading from inventory.txt
FILE *wptr=fopen("total.txt","wb");       //writing into total.txt
  
char item[20][20];       //considering maximum string length of item as 20 and 20 as limit to number of items
float total_value;
float total=0;
  
  
float number_of_units;
float unit_cost;
  
fprintf(wptr," Fruit Co's Inventory Report"); //writing into file
fprintf(wptr," ");
  
fprintf(wptr,"ITEM NUMBER OF UNITS UNIT COST TOTAL VALUE"); //writing into file
fprintf(wptr," ");
  
int i=0;
while(fscanf(rptr," %s %f %f ",item[i],&number_of_units,&unit_cost)==3)   //reading from file
{
total_value=number_of_units*unit_cost;   //total_value of each items
total=total+total_value;       //summing all value as described in problem
  
fprintf(wptr," %s %f %f %f ",item[i],number_of_units,unit_cost,total_value);
fprintf(wptr," ");   //writing into file
i++;
}
fprintf(wptr," ");
fprintf(wptr," Inventory Total %f ",total);
fprintf(wptr," ");       //writing into file
  
  
return 0;
}

//inventory.txt input file

orange 20 8.99
Apple 10 0.99
Banana 2000 0.82
Apricot 5000 1.21

//total.txt ,output file
