problem 1) prepare a program to read and prepare student records from text file “Student.txt”.

problem 2) prepare a program to read and prepare employee records from binary file “emp.dat”.

• using structures

• using classes

problem 3) prepare a program that opens a file “message.txt” and displays its contents.

problem 4) prepare a program to copy the contents of the file “abc.dat” to “xyz.dat”.

problem 5) A binary file “stu.dat” contains student records.

prepare a program to create a binary file “stusort.dat”, which contains all the records of “stu.dat” in the sorted order of roll number.

problem 6) prepare a program to count number of employee records in a binary file “emp.dat” whose department number is 10.

• using structures

• using classes

problem 7) prepare a program to search a given employee record by employee number or name in a binary file using structures / classes.

problem 8) There are 100 records present in a file with the following structure:

Sturct item
{

int itemcode, qty;

char itemname[20];

};

prepare a program to read these records and arrange them in ascending order of item code and prepare them in target file separately.

problem 9) prepare a program to modify a given employee record in a binary file using structures / classes.

problem 10) prepare a program to delete a given employee record in a binary file using structures / classes.

problem 11) prepare a program to count the number of characters, alphabets, vowels and consonants in a file “poem.txt”.

problem 12) prepare a program to count the number of words and lines in a file “poem.txt”.

problem 13) prepare a program to count number of spaces, tabs and newline characters in a file“Notes.txt”.

problem 14) Suppose that a text file named TEXT1.TXT already contains some text written into it, prepare a program that reads file TEXT1.TXT and create a new file named TEXT2.TXT,which shall contain only those words from the file TEXT1.TXT which don’t start with an uppercase vowel ( i.e. with ‘A’, ‘E’, ‘I’ , ‘O’, ‘U’).

problem 15) prepare a program which takes “story.txt” as input file and creates a new file “story1.txt” by replacing all the spaces with “-“, tabs by “%” and newlines by “$”.
