dimensional array of integers.
12 3 9 14

24 25 16 31
If the 2D array is
19 32 45 27

11 5 28 18

The resultant ID arrays is 12, 3, 9, 24, 25, 45, 9, 5, 18 [3]
d) Write a function in C++ to insert and delete a node containing city’s information (i.e. city
name and its population) from a dynamically allocated Queue of cities. [4]
e) Convert the following infix expression to its equivalent postfix expression showing stack contents
for the conversion: (A + B) * ( C ^ ( D – E ) + F ) - G [2]

Q.4 a) Write appropriate C++ commands to do the following:
(i) To open a file named RESULT.DAT for editing records
th
(ii) To got to the 70 byte in a file DATA.DAT [1]
b) Write a C++ program to display the data in a text file TEXT.DAT. While displaying the data,
if the number of lines exceed by 20, the text file should be displayed screen by screen. [2]
c) Given a binary file “AMOUNT.DAT” , containing records of the given class outstand type.
class outstand
{
int memno;
int outamt;
public:
void getit( )
{ cin>>memno>>outamt; }
void putit( )
{ cout<<memno<<outamt; }
int returnamt( )
{ return outamt; }
int ret_memno()
{ return memno; }
};
Write a function to delete a particular memno from the file
“AMOUNT.DAT” . [2]
