C++ header files

My header file looks like this:

#ifndef PPMIMAGE_H_
#define PPMIMAGE_H_
class PpmImage{
   public:
       void readImage(char* data);
       void setRows(int row){
           rows = row;
       }
       void setCols(int col){
           cols = col;
       }
       void setDataArray(int size){
           data = new char[size];
       }
       int getRows(){
           return rows;
       }
       int getCols(){
           return cols;
       }
       char* getDataArray(){
           return data;
       }

   private:
       int rows;
       int cols;
       char* data;
};
#endif

Now, I need to implement readImage() function in my .cpp file which now only contains the main method:

#include "ppmImage.h"

using namespace std;

int main(int argc, char** argv) {

   PpmImage image;
   image.setRows(-1);
   image.setCols(-1);
   int rows = image.getRows();
int cols = image .getCols();

}

how to implement the readImage() function in my .cpp?

Explanation / Answer

PpmImage.h file:

#ifndef PPMIMAGE_H_
#define PPMIMAGE_H_
class PpmImage{
private:
int rows;
int cols;
char* data;
public:
void readImage(char* data);
void setRows(int row){
rows = row;
}
void setCols(int col){
cols = col;
}
void setDataArray(int size){
data = new char[size];
}
int getRows(){
return rows;
}
int getCols(){
return cols;
}
char* getDataArray(){
return data;
}
};
#endif

=============================================

PpmImage.cpp file:

save below code in ppmImage.cpp file

#include <iostream>
#include "ppmImage.h"
using namespace std;

void PpmImage::readImage(char* data)
{

//Here you can write the code

}

==========================================

client code: main.cpp

#include <iostream>
#include "ppmImage.h"
using namespace std;
int main(int argc, char** argv) {
PpmImage image;
image.setRows(-1);
image.setCols(-1);
int rows = image.getRows();
int cols = image .getCols();
//using image you can call readImage function as per your requirement.
return 0;
}

finally compile and run the main.cpp file
