Question

Write a program to read the parts.txt file and display the cost of inventory for each of the part classes. The file contains parts of class A, B, C and D. An example of a typical line in this file would be: P-11191 A 10 34.29 This is part number P-11191, a class A part, of which there are 10 in stock and each costs $34.29. Your program, therefore, would increment the Count of class A parts by one and add $342.90 (10 $34.29) to the class A inventory. Note that the count is only incremented by 1, not by 10 this tracks the number of unique different types of class A parts, not the total in-stock quantity of each respective part. The parts file is on Canvas in this week's module in .zip format. After downloading it, right click and choose Extract.

Explanation / Answer

#include <iostream>

#include <fstream>

#include <string>

using namespace std;

int main() {

ifstream file("input.txt");

int countA = 0, countB = 0, countC = 0, countD = 0, unknown = 0;

double valueA = 0, valueB = 0, valueC = 0, valueD = 0, unknownValue = 0;

string part;

char type;

int stock;

double cost;

while(file >> part >> type >> stock >> cost) {

if(type == 'A') {

countA ++;

valueA += stock * cost;

} else if(type == 'B') {

countB ++;

valueB += stock * cost;

} else if(type == 'C') {

countC ++;

valueC += stock * cost;

} else if(type == 'D') {

countD ++;

valueD += stock * cost;

} else {

unknown ++;

unknownValue += stock * cost;

}

}

cout << "----------------------------INVENTORY REPORT----------------------------" << endl;

cout << "A parts Count: " << countA << " Value of Inventory: " << valueA << endl;

cout << "B parts Count: " << countB << " Value of Inventory: " << valueB << endl;

cout << "C parts Count: " << countC << " Value of Inventory: " << valueC << endl;

cout << "D parts Count: " << countD << " Value of Inventory: " << valueD << endl;

cout << "Unknown parts Count: " << unknown << " Value of Inventory: " << unknownValue << endl;

return 0;

}
