i try to read a.wav and create the same file as receive.wav

but receive.wav is not the same as a.wave
receive.wav is different after getting '00' in hexa format.
what is the problem ?

FILE *fp=fopen("a.wav","rb");
FILE *fp2 = fopen ("receive.wav" , "wb");

// obtain the file size
fseek (fp , 0 , SEEK_END);
lSize = ftell (fp);
rewind(fp);

// allocate memory to contain the whole file.
buffer = (char*) malloc (lSize);
if (buffer == NULL) return FALSE;

// copy the file into the buffer.
fread (buffer,1,lSize,fp);

if(fp2 != NULL)
{
cout<<"size"<<fwrite (buffer , 1 , lSize , fp2)<<endl;
fclose (fp2);
}
fclose (fp);
