#include "Cpawn.h"
#include "Cpiece.h"






void main(){
	char location[50];


	char piece;
	int oldrow=0,oldcolumn=0,newrow=0,newcolumn=0,check =0,end=0;
	Cboard myboard;
	Cpawn mypawn(&myboard);
	


	Cpiece *piecer = &mypawn;
	do{
	std::cout<<std::endl;
	
		(myboard).printboard();
		


		std::cout<<std::endl;
	std::cout<<"please enter location";
	std::cin>>location;
	check =(myboard).validateuserinput(location,&newcolumn,&newrow,&oldrow,&oldcolumn);
	//piece = (*myboard).board[]
	if(check==0){
		std::cout<<"correct";
		
		if((*piecer).movepiece(&newcolumn, &newrow,&oldrow,&oldcolumn)==1){
			(myboard).moveer(&newrow,&newcolumn,&oldrow,&oldcolumn);
			(myboard).move();
	}


		
	}
	else{
		std::cout<<"error";
	}
	end++;
	}while(end!=8);
}

Cpawn.h

Code:

#pragma once#include "Cpiece.h"


class Cpawn:public Cpiece
{
public:
	virtual char getcolor();
	 virtual char setcolor(char colour);
	virtual char getpiece();
	virtual int movepiece(int *newcolumn, int *newrow, int *oldrow,int *oldcolumn);
	 char col;
	 Cboard *mboard;
	Cpawn(Cboard *board);
};

Cpawn.cpp

Code:

#include <iostream>#include "Cpawn.h"
#include "Cpiece.h"
#include"Cboard.h"


 char Cpawn::getpiece(){
	   
		return 'p';
	}
 Cpawn::Cpawn(Cboard *board){
	 mboard = board; 
     }
 char Cpawn::setcolor(char colour){
	 col = colour;
  return col;
 }
 char Cpawn::getcolor(){
	 return col;
 }
 int Cpawn::movepiece(int *newcolumn, int *newrow,int *oldcolumn,int *oldrow){
	 int correct =0;
	 int old ,old1;
	char piece;
	 old =*oldrow;
	 old1 = *oldcolumn;
	 piece= mboard->board[1][1]->getcolor;
	 if(*oldrow == *newrow && *oldcolumn-1 == * newcolumn||*oldrow == *newrow && *oldcolumn+1 == * newcolumn){
		correct =1;
	}


	return correct ;
 }

Cpiece.h

Code:

#pragma once

class Cpiece
{
protected:


	
public:
	virtual char getcolor() =0;
	virtual char setcolor(char colour)=0;
	virtual char getpiece()=0;
	virtual int movepiece(int *newcolumn, int *newrow, int *oldrow,int*oldcolumn)=0;
	char getcolumn();
	char getrow();
	//Cboard bord;
	void setvalue(int oldcolumn,int oldrow);
	//Cpiece (void);
	//Cpiece(Cboard board);
	int row,column;
	


	//~Cpiece(void);
};

cpiece.cpp

Code:

#include "Cpiece.h"



/*Cpiece::Cpiece(void)
{
}


/*Cpiece::Cpiece(Cboard myboard){
	bord = myboard;
}*/


/*Cpiece::~Cpiece(void)
{
}*/
void Cpiece::setvalue(int oldcolumn,int oldrow){
	
	 row =oldrow ;
	 column = oldcolumn;
}
 char Cpiece::getcolumn(){


 return column;
}


char Cpiece::getrow(){
	return row;
}

these are erros that im facing and could not correct
