#ifndef SPRITE_H
#define SPRITE_H
#include "drawEngine.h"

enum
{
    SPRITE_CLASSID,
};

struct vector
{
    float x;
    float y;
};

class Sprite
{
public:
    Sprite(DrawEngine *de, int s_index, float x= , float y=1, int i_lives=1);
    ~Sprite();
    vector getPosition(void);
    float getX(void);
    float getY(void);
    virtual void addLives(int num = 1);
    int getLives(void);
    bool isAlive(void);
    virtual bool move(float x, float y);
protected:
    DrawEngine *drawArea;
    vector pos;
    int spriteIndex;
    int numLives;
    int classID;
    void draw(float x, float y);
    void erase(float x, float y);
    vector facingDirection;
};

#endif

sprite.cpp

Code:

#include "sprite.h"
Sprite::Sprite(DrawEngine *de, int s_index, float x = 1, float y = 1, int i_lives = 1)
{
    drawArea = de;
    pos.x = x;
    pos.y = y;
    spriteIndex = s_index;
    numLives = i_lives;
    facingDirection.x = 1;
    facingDirection.y = 0;
    classID = SPRITE_CLASSID;
}
Sprite::~Sprite()
{
    erase(pos.x,pos.y);
}
vector Sprite::getPosition(void)
{
    return pos;
}
float Sprite::getX(void)
{
    return pos.x;
}
float Sprite::getY(void)
{
    return pos.y;
}
void Sprite::addLives(int num)
{
    numLives += num;
}
int Sprite::getLives(void)
{
    return numLives;
}
bool Sprite::isAlive(void)
{
   
    return (numLives > 0);

}
bool Sprite::move(float x, float y)
{
    erase(pos.x,pos.y);
    pos.x += x;
    pos.y += y;
    facingDirection.x = x;
    facingDirection.y = y;
    draw(pos.x,pos.y);
    return true;
}
void Sprite::draw(float x, float y)
{
    drawArea->drawSprite(spriteIndex,x,y);
}
void Sprite::erase(float x, float y)
{
    drawArea->eraseSprite(x,y);
}

Code:

Sprite(DrawEngine *de, int s_index, float x= , float y=1, int i_lives=1);

Looks like you're assigning ... nothing to x. But you're trying to.

yes i got it i am sorry i got the issue

in header file and source file i am trying to declare value
Sprite(DrawEngine *de, int s_index, float x=1 , float y=1, int i_lives=1);
so i removed the value Sprite(DrawEngine *de, int s_index, float x, float y, int i_live);
in header its working with no issue

sorry for disturbing u people
