(2018-2019 Sub Code: 083 Paper Code: 91)

(1 Mark for only the final answer as ​UV*WZ-X/+ ​)

4. (a) A text file named ​MATTER.TXT contains some text, which needs to be displayed 3
such that every next character is separated by a symbol ‘#’.

Write a function definition for ​HashDisplay​() in C++ that would display the entire
content of the file ​MATTER.TXT​ in the desired format.
Example:
If the file MATTER.TXT has the following content stored in it:

THE WORLD IS ROUND

The function ​HashDisplay​() should display the following content:
T#H#E# #W#O#R#L#D# #I#S# #R#O#U#N#D#

Ans void HashDisplay()
{
char ch;
ifstream F("MATTER.TXT" );
while(F.get(ch))
cout<<ch<<'#';
F.close(); //IGNORE
}

OR
Any other correct function definition

(1 Mark for opening ​MATTER.TXT​ correctly)
(1 Mark for reading each character ​(using any method)​ from the file)
(½ Mark for displaying the character)
(½ Mark for displaying a # following the character)

(b) Write a definition for function TotalTeachers( ) in C++ to read each object of a 2
binary file SCHOOLS.DAT, find the total number of teachers, whose data is stored
in the file and display the same. Assume that the file SCHOOLS.DAT is created
with the help of objects of class SCHOOLS, which is defined below:

class SCHOOLS
{
int SCode; // School Code
char SName[20]; // School Name
int NOT; // Number of Teachers in the school
public:
void Display()
{cout<<SCode<<"#"<<SName<<"#"<<NOT<<endl;}
int RNOT(){return NOT;}
};

Ans void TotalTeachers()
{
ifstream F;
F.open("SCHOOLS.DAT",ios::binary);
