Question

Using PUTTY

We will create functions.h and functions.cpp to separate the read and write function from main function. Use the following steps:o Create a directory called lab07o Upload the yourlastnameFirstnameLab06a.cpp from your computer to the csegrid.

Create a functions.h file with the following:

#ifndef _READWRITE

#define _READWRITE

void readWrite( );

#endif

Create a functions.cpp#include functions.hImplement readWrite() with the code in case 1 of the main.cpp.

Modify yourlastnameFirstnameLab06a.cpp

#include functions.h

Call readWrite for case 1 (instead of the case1 code)

Compile your code with the command:g++ -lab06a main.cpp functions.cpp

#ifndef _READWRITE #define _READWRITE void readWrite( );

#endif

Create a functions.cpp #include functions.h Implement readWrite() Modify main.cpp #include functions.h Call readWrite

Compile your code with the command: g++ -o lab06a yourlastnameFirstnameLab06a.cppfunctions.cpp

As you have not provided anything for the function readWrite(), I am solving your problem by defining a dummy function that simply reads and writes files.

main.cpp

#include <iostream> #include "functions.h" int main() { readWrite(); return 0; }

functions.h

#ifndef _READWRITE #define _READWRITE void readWrite( ); #endif

functions.cpp

#include <iostream> #include <fstream> #include "functions.h" using namespace std; void readWrite() { // Writing // Create and open a text file ofstream MyFile("filename.txt"); // Write to the file MyFile << "data to be written\n"; // Close the file MyFile.close(); // Reading // Create a text string, which is used to output the text file string myText; // Read from the text file ifstream MyReadFile("filename.txt"); // Use a while loop together with the getline() function to read the file line by line while (getline (MyReadFile, myText)) { // Output the text from the file cout << myText<<endl; } // Close the file MyReadFile.close(); }

filename.txt

Output
