Question

  rewrite the c++ program processes into     functions by performing the following:  2.  Create int function(s) for opening the input and output files.  These     opens may be in the same function.  This function MUST RETURN an int value      to indicate the success or failure of the open(s).  Test this value and      take appropriate action after the function call.  This function MUST have     the following parameters, in any order:       a.  input file stream       b.  output file stream      3.  Create a void function to read the data file.  This function MUST have the     following parameters, in any order:       a.  input file stream       b.  OUT parameter to return the total of all values       c.  OUT parameter to return the number of values read        4.  Create a value returning function (I'm leaving it up to YOU to choose     the correct type) to return the avg of the numbers read.  This function     MUST have the following parameters, in any order:       a.  IN parameter to pass in the total of the numbers read       b.  IN parameter to pass in the number of values read        5.  Create void function(s) for closing the input and output files.  These     closes may be in the same function.  This function MUST have the following     parameters, in any order.       a.  input file stream       b.  output file stream  6.  Move the global variables (defined before main in reWriteThis.cpp)     and place them within the appropriate functions.  Some will be      needed with the related function, some will still be needed in main.      7.  FOR PRACTICE, do NOT use the same variable names as ARGUMENTS in the     function call and PARAMETERS in the function heading definition.      8.  You MUST use function prototypes (before main) and you MUST define     your functions AFTER main.      9.  The console (cout) and file writes remain in main.  10. Either create a file named inFile.txt that contains:       a.  The number of values to add       b.  A number of integer values matching the number read in a.         OR             c.  Download and use attached inFile.txt **inFile.txt ( 12 1 6 8 90 34 23 45 23 12 59 33 24)

 #include <iostream> #include <string> #include <fstream> #include<cstdlib> // for system("pause")  using namespace std;  // global variables; are used anywhere within the program without re-definition  string ifileName, ofileName; ifstream inData; ofstream outData; int numValues, total, i, num; float avg;  int main () {    ifileName = "inFile.txt";   inData.open(ifileName.c_str());   if (!inData) {     cout << "Error opening file: " << ifileName << ".  Exiting program..." << endl;     return 0;   }    inData >> numValues;    for (i = 0; i < numValues; i++) {     inData >> num;     total += num;   }    avg = float(total) / float(numValues);    ofileName = "outFile.txt";   outData.open(ofileName.c_str());   if (!outData) {     cout << "Error opening file: " << ofileName << ".  Exiting program..." << endl;     return 0;   }    cout << "You entered " << numValues << " numbers totaling "  <<  total << " with a average of " << avg << endl;   outData <<  "You entered " << numValues << " numbers totaling "  <<  total << " with a average of " << avg << endl;    inData.close();   outData.close();    system("pause");    }

Explanation / Answer

2) #include #include using namespace std; int open(ifstream &in, ofstream &out) { if(in.is_open() && out.is_open()) { return 1; } else { return 0; } } int main() { return 0; }
