Thread: Passing a string to a class

Hello all,

OK, here's the deal. I have this assignment where I am trying to implement a class method. In it I am trying to calculate the total of uppercase letters in a string. My problem is that I can't grasp how to pass the string to the accessor function. At the moment my program will not even compile giving me this error;

Code:

71 C:\C++Course\A1-1.cpp invalid conversion from `char*' to `int'

Here is my code as it stands now;

Code:

#include <iostream>
#include <cctype>    // Not sure if this is really needed here 
#include <string>

using namespace std;

class Word           // Declaring the class object
   {
    public:          // public section
                     
    int GetNumberOfUppercase();                       // accessor function
    void SetNumberOfUppercase(int UppercTotal);       // accessor function
                                                    
    private:                                          // begin private section  
    int UppercaseTotal;                               // member variable
    
    };                    
          //---------------------------------------------------
          // GetNumberOfUppercase, public accessor function
          // return number of uppercase letters
          //---------------------------------------------------
    
    int Word::GetNumberOfUppercase()
    {
        return UppercaseTotal;
    } 
    //--------------------------------------------------
    // Definition of SetNumberOfUppercase, public
    // accessor function
    // return sets UppercaseTotal member
    //--------------------------------------------------
    void Word::SetNumberOfUppercase(int UppercTotal)
     { 
          char WordArray[25];  
          int i,UpperTotal;
      int size = strlen(WordArray);
         
      for(int i=0; i<size; i++)
        { if (isupper(WordArray[i]))
                  UpperTotal++;
           }
     UppercaseTotal = UpperTotal;  
    } 
    
//----------------------------                              
// begin main processing
//----------------------------

int main()
{ 
    char line[25];
  
  //----------------------------------------------------------------------
  // Want to pass this value to SetNumberOfUppercase  ?????   
 // -----------------------------------------------------------------------
    cout<<"Enter a string 25 Char. long Max : ";
    cin >> line;
    
    Word Input;   

// Compile error here 
    Input.SetNumberOfUppercase(line);
    
    cout<< "The word you entered " << line << " has " << endl; 
    cout<< Input.GetNumberOfUppercase() << " Uppercase Letters" << endl;
 
  // Pause to look at the results
  
     system("pause");
     return 0;
          
} // end main

Now I've been reading a lot but somehow can't find exactly what I'm looking for. My instructor suggested that I declare a char* input. Initialize it with say input= new char[25]; but I am not sure exactly how to go about it and my instructor won't be available for several more days and I would really like to go forward with this. Can someone point me to a link or explain how to proceed with a simple example?

Thanks in advance,

SetNumberOfUppercase should take a char*, not an int (or the class should take a char* in its constructor if you knew how to do that). You are passing line, which is a C style string to the SetNumberOfUppercase function, so the SetNumberOfUppercase function parameter should accept a char* to hold the string. How familiar are you with function parameters and types?

Incidentally, C style strings don't make much sense in C++, the C++ string class would usually be better.
