Make sure your Solution Explorer window +* is visible. If not, you can display it by selecting Solution +* Explorer (or Ctrl+Alt+L). +* 3) Open the input file by simply double clicking the name of the +* file in your Solution Explorer. +* 4) Build and execute the program. +* 5) Update the file paths below to correctly represent the path you +* created. +* 6) Rebuild and execute the program. +* 7) Examine the code and the output and notice the use of +* parallel arrays. +* 8) Add the output file created via the execution of +* your program to your Project. Execute your program again +* and notice how Visual Studio has rewritten your output file +* and asks if you would like to reload the file (select Yes). +* 9) Examine the contents of both the input and the output file. +* 10) Fix all the problems in your code that exist in relation to +* the output. Verify that your output is appropriate for your + input file. +* 11) Build and execute your code until you have all errors +* removed and all the output is correct. +* +* Debugging Exercise 2 +* +* 1) Replace the double slashes (\\) in the input file open statement +* with only a single slash +* (i.e., inFile.open("C:\TEMP\Chap_11_data.txt"). +* 2) Build your code, noticing the impact of the invalid path you +* created in the previous step. +* 3) Replace the backslashes as they were. +* 4) Change both the input and output filenames so they are +* invalid. +* 5) Update the file related error messages within the code +* to also provide the specific name of the file that is having a +* problem. +* 6) Rebuild and execute your program to verify that your messages +* are correct. +* 7) Correct the path names. +* 8) Build and execute your code and carefully check your +* output on both the console and in the output file. +* +********************************************************************/ +#include <iostream> +#include <fstream> // For the files!!!! +#include <iomanip> // For manipulators & formatting options +using std::cin; +using std::cout; +using std::endl; +using std::setw; +using std::ios; + +using std::ifstream; +using std::ofstream; + +const int EMPLOYEES = 20; +const int MAX = 21; + +int ReadData(ifstream& inFile, ofstream& outFile, char name[][MAX], int age[]); +void WriteOutputFile(ofstream& outFile, char name[][MAX], int age[], + int counter); +void PrintTotalsAndSummary(ofstream& out, int totalRecords); + +int main() +{ + char name[EMPLOYEES][MAX]; + int age[EMPLOYEES]; + int record_counter(0); + + ifstream inFile; + + // Notice how this automatically opens the file + ofstream outFile("C:\\TEMP\\Chap_11_Report.txt"); + + inFile.open("C:\\TEMP\\Chap_11_data.txt"); + + if (inFile.is_open()) + { + record_counter = ReadData(inFile, outFile, name, age); + inFile.close(); + + if (outFile.is_open()) + { + WriteOutputFile(outFile, name, age, record_counter); + PrintTotalsAndSummary(outFile, record_counter); + outFile.close(); + } + else + { + cout << "Trouble Opening File"; + cout << "\n\n\t\t ** About to EXIT NOW! ** "; + } + } + else + { + cout << "Trouble Opening File"; + cout << "\n\n\t\t ** About to EXIT NOW! ** "; + } + return 0; +} +int ReadData(ifstream& inFile, ofstream& outFile, char name[][MAX], int age[]) +{ + int counter = 0; + inFile >> name[counter] >> age[counter]; // Priming Read + + while (!inFile.eof()) + { + cout << setiosflags(ios::left) << setw(25) + << name[counter] << resetiosflags(ios::left) + << setw(4) << age[counter] << endl; + counter++; + inFile >> name[counter] >> age[counter]; + } + + return counter; +} +void WriteOutputFile(ofstream& outFile, char name[][MAX], int age[], int counter) +{ + outFile << " Here is the Output File" << endl; + for (int r = 0; r <= counter; r++) + { + outFile << setiosflags(ios::left) << setw(25) + << name[r] << setw(4) + << resetiosflags(ios::left) << age[r] + << endl; + } +} +void PrintTotalsAndSummary(ofstream& outFile, int totalRecords) +{ + // To screen + cout << "\n\n\t** Total Records: " << totalRecords << " **\n" + << "\t\t The End \n"; + + // To file + outFile << "\n\n\t** Total Records: " << totalRecords << " **\n" + << "\t\t The End \n"; +} |
