The code I ran was:

#include #include #include #include using namespace std; int main$()\{//$ Open input and output files ifstream inputFile$("$inventory$.$txt$")$; $//$ Input file ofstream outputFile$("$inventory$\_$report.txt$")$; $//$ Output file $//$ Check if the file is opened successfully if $(!$inputFile$)\{$ cout $$ "Error opening the input file!" $$ endl; return $1$; $\}//$ Variables to store data from the file string itemName; int numberOfUnits; double unitCost, totalValue, grandTotal $=0$; $//$ Print header to the output file outputFile $$ fixed $$ setprecision$(2)$; outputFile $$ "Inventory Report For Jane Doe International Hardware" $$ endl; outputFile endl; outputFile $$ setw$(15)$ left $$ "ITEM" $$ setw$(15)$ right $$ "NUMBER OF UNITS" $$ setw$(10)$ "UNIT COST $($$$)"$ setw$(15)$ "TOTAL VALUE $($$$)"$ endl; outputFile endl; $//$ Read data from input file and calculate the total value for each item while $($inputFile $>>$ itemName $>>$ numberOfUnits $>>$ unitCost$)\{$ totalValue $=$ numberOfUnits $*$ unitCost; grandTotal $+=$ totalValue; $//$ Print each item in the formatted table outputFile $$ setw$(15)$ left $$ itemName $$ setw$(15)$ right $$ numberOfUnits $$ setw$(10)$ unitCost $$ setw$(15)$ totalValue $$ endl; $\}//$ Print total inventory value, right aligned under TOTAL VALUE column outputFile endl; outputFile $$ setw$(40)$ left $$ "Inventory Total $($$$)"$ setw$(15)$ right $$ grandTotal $$ endl; $//$ Close the files inputFile.close$()$; outputFile.close$()$; cout $$ "Inventory report generated successfully." $$ endl; return $0$; $\}$

Have also confirmed that I have the running project and text document on the same folder. Somehow I keep getting an error indicating that it cannot open the input file.
