each time when I write and read from eeprom 24c04 I am getting the same value 49

Sir, I am trying to write 34 into the eeprom at address location 0x0000, but whenever I read and dislpay it on lcd, 49 is displayed. please help me.

my code

sbit SCL=P3^7; // Port pin for SCL line
sbit SDA=P3^6; // Port pin for SDA line

void i2c_delay(void); // I2C Clock delay
void i2c_start(void); // Generates a I2C Start condition
void i2c_stop(void); // Generates a I2C Stop condition
void i2c_wbyte(char i2c_wb); // Writes a single byte from I2C Slave
unsigned char i2c_rbyte(void); // Reads and returns a single byte from I2C Slave
char i2c_ack(void);
void i2c_nack(void);
void i2c_write(char id, char add,char dat);
unsigned char i2c_read(char id,char add);

void i2c_delay(void)
{ char a; for(a=0;a<80;a++);
}

void i2c_start(void)
{ SCL = 1; i2c_delay(); SDA = 1; i2c_delay(); SDA = 0; i2c_delay(); SCL = 0; i2c_delay();
}

void i2c_stop(void)
{ //SDA_Dir = 1; //SDA pin as output SDA = 0; i2c_delay(); SCL = 1; i2c_delay(); SDA = 1; i2c_delay(); SCL = 0;
}

void i2c_wbyte(unsigned char i2c_wb)
{ char a; //DA_Dir = 1; // Set SDA pin as output for(a=0;a<8;a++) // Send 8 bits { SCL = 0; i2c_delay(); if(i2c_wb & (0x80 >> a)) { SDA = 1; } else { SDA = 0; } i2c_delay(); SCL = 1; i2c_delay(); }

}

unsigned char i2c_rbyte(void)
{ char a; unsigned char b; b=0; //SDA_Dir = 0; // Set SDA pin as input for(a=0;a<8;a++) { SCL = 1; i2c_delay(); if(SDA) { b |= (0x80 >> a); // Set data bit on SDA line } i2c_delay(); SCL = 0; i2c_delay(); } return(b);
} char i2c_ack(void)
{ char a; //SDA_Dir = 1; // Set SDA pin as output i2c_delay(); SCL = 0; i2c_delay(); SDA = 1; i2c_delay(); SCL = 1; i2c_delay();

//SDA_Dir = 0; // Set SDA pin as input i2c_delay(); a = SDA; i2c_delay(); SCL = 0; i2c_delay(); return(a);
}

void i2c_nack(void)
{ //SDA_Dir = 1; // Set SDA pin as output SDA = 1; i2c_delay(); SCL = 1; i2c_delay(); SCL = 0; i2c_delay();
} void i2c_write(unsigned char id, unsigned char add, unsigned char dat)
{ i2c_start(); i2c_wbyte(id); i2c_ack(); i2c_wbyte(add); i2c_ack(); i2c_wbyte(dat); i2c_ack(); i2c_stop();
}

unsigned char i2c_read(unsigned char id,unsigned char add)
{ unsigned char rd; i2c_start(); i2c_wbyte(id); i2c_ack(); i2c_wbyte(add); i2c_ack(); i2c_start(); i2c_wbyte((id|0x01)); i2c_ack(); rd = i2c_rbyte(); i2c_nack(); i2c_stop(); return(rd);
} main()
{ unsigned char v=34; unsigned char dat=0; i2c_write(0xA0,0x0000,v); dat=i2c_read(0xA0,0x0000); send2lcd(dat);
} the delay between read and write correct?
the delay between scl and sda line, is ok? please help me

thanks in advance
