Thread: I need Help writing a loop with an incrament

Hello I been working on this code but I cant get it too loop back untill all values in this file are printed out on the screen. The code will print out just the "cout" statements only one time on screen but will not produce the values. Also it wont loop back and give me the results of the whole list. Also there is a warning on thecompiliar that says... 'rec' is assigned a value that is never used. Here is the code any help will be greatly appreciated. Thank you

Code:

void main() 
{ 
   int z; 
   cout<<"test"<<endl; 
   AcademicRec(); 
   cin>>z; 
} 



void AcademicRec()       //Reading the AcademicRec's File 
{ 

   ifstream acctFile ("Accounts1.dat");   // This is the accounts database file 

   char line[200]; 
   char rec = 0; 
   int z; 
while(!acctFile.eof()) 
{ 
     acctFile.getline(line,200); 
     if(line[0]==rec) 
     { 

            acctFile.seekg((acctFile.tellg()-strlen(line)),ios::beg); //seek to the begginning of the line 
            acctFile.getline(line,200,' '); //get everything up to the space 
            cout << "Social Security #: " << line << endl; 
            acctFile.getline(line,200,' '); 
            cout << "First Name: " << line << endl; 
            acctFile.getline(line,200,' '); //get everything up to the space 
            cout << "Last Name: " << line << endl; 
            acctFile.getline(line,200,' '); 
            cout << "Phone Number: " << line << endl; 
            acctFile.getline(line,200,' '); //get everything up to the space 
            cout << "Home Street: " << line << endl; 
            acctFile.getline(line,200,' '); 
            cout << "Home Town: " << line << endl; 
            acctFile.getline(line,200); //get everything up to the space 
            cout << "State: " << line << endl; 

     } 
} 
    rec++; 
    cin >>z; 
}

Code:

    rec++;

I may be wrong but can you increment a char?

Yes you can, it is just like any other number only that its 8-bit. Integers are normally 32-bits (16-bits on older machines, 64-bits on cutting-edge computers).

Thanks Speedy5 and sorry sell682.
