1. a) What is the difference between ios::app and ios::ate?
b) Explain significance eof() function.
 
2. Observe the program segment carefully and fill the missing statements where statement1 is to position the file pointer , statement2 is to write the record:
 
class student
{
int student_no;
char student_name[20];
int mark;
public:
void enterDetail( );
void showDetail( );
void change_mark( ); //Function to change the mark
int getStudent_no( ){ return student_no;}
};
void modify( int y )
{
fstream File;
File.open( “student.dat”, ios::binary|ios::in|ios::out) ;
student i;
int recordsRead = 0, found = 0;
while(!found && File .read((char*) & i , sizeof (i))
{
recordsRead++;
if(i . getStudent_no( ) = = 25 )
{
i . change_mark( );
_________________________//Missing statement 1 ,to position the file pointer
_________________________//Missing statement 2, to write the record
found = 1;
}
}
if( found = = 1)
cout<<”Record modified” ;
File.close() ;
}
 
3. Write a function in C++ add more records at the end of a file “CUST.DAT”, assuming the binary file is containing the objects of the following class:
class ORG
{
char Account_holder_name[20];
int Account_Number; float Balance;
public:
void input()
{ gets(Account_holder_name);
cin>> Account_Number>> Balance;
}
void display()
{
cout<
}
};
 
4. Given a sorted binary file BOOK.DAT(sorted in ascending order of bookid)
containing records of the following type:
class Book {
int bookid;
char Bname[20], status; // „A‟- active ,‟ I‟- inactive.
public:
void readdetails( )
{
cin>>bookid; gets(Bname); cin>>status;
}
void displaydetails( )
{
cout<
}
int getid( ) { return bookid }
};
Write a function to insert a new book record (object) in the sorted file in the right position.
 
5. Explain a) NULL pointer b) Dynamic memory allocation
 
6. char Name[ ]= “IntRAneT”;
char* T=Name;
T+=3;
cout<<*T<<*Name<
cout<<(T+2)<
}
 
7. Find the output of the following program segment:
int A[ ]={12,18,20, 35,40};
int *p=A;
while(*p<30)
{
if(*p%3!=0)
*p=*p+5;
else
*p=*p+2;
p++;
}
for(int j=0;j<=4;j++)
{
cout<
if(j%3==0)
cout<
}
cout<
}
 
8. #include
#include
int a=20;
void main()
{
void demo(int,int*);
int a=10;int* p=&a;
demo(::a,p);
cout<<::a<<":"<
}
void demo(int y,int *z)
{
y*=*z;
*z+=a;
cout<
}
