int Flight :: CountRec( )
{
Flight Obj;
fstream File;
File.open(“Flight.Dat”, ios::in | ios::binary);
……………………………………………… // Statement 1, to go to end of file
int bytes =……………………………………// Statement 2, to find no. of bytes
int count = bytes / sizeof(Obj);
File.close( );
return count;
}

Class DOLLS
{
int Dcode;
char Dname[20];
char Agerange[20];
void enter()
{
cin>>Dcode;
gets(Dname);
gets(Agerange);
}
void Display()
{
cout<
}
char* Whatage(){ return Agerange;}
};
 
4. Write a function in C++ to delete the record of a given membership number(Mno) from a binary file ‘Club.dat’ containing records of the following structure:
 
struct Member
{
int Mno; //membership number

P=Num;
Text++;
cout<<*P<<*Text<
Text++;P++;
cout<<*P<
}
 
7. Find the output of the following program segment: (assume all header files are included)
 
int A[ ]={12,18,20, 35,40};
int *p=A;
while(*p<40)
{
if(*p%3==0)
*p=*p+4;
else
*p=*p+3;
p++;
}
for(int j=0;j<=4;j++)
{
cout<
if(j%3==0)
cout<
}
cout<
}
 
8. Find the output of the following code snippet: (assuming all required header files are included)
 
void NewText(char str[ ], int & pos)
{
char * p = str;
int length = strlen(p);
for( ; pos < length – 4; pos += 2 , p++)
{
*(p + pos) = toupper(*(p+pos));
}
cout<
}
